REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!

TCL L32D2930 LCD TV, SERVICE MODE AND SERVICE ADJUSTMENTS, SOFTWARE UPDATE, LAN TEST, POWER BOARD SCHEMATIC



TCL L32D2930/MT565EP1-LA - LED Smart DTV - Factory mode, software update, Network configuration and more
CPU: Quad Core A7 1GHz
GPU: Dual Core MALI450MP2 400MHz
OS: Linux
Memory/flash: 8Gb DDR3 / 4GB Flash
Power Supply: AC 100V-240V 50/60Hz
TV system: ATV: PAL M / N; NTSC-M;
DTV: ISDB-T, GINGA
AV system: PAL, NTSC
To communicate with TV product for debugging, adjustment and so… it’s required suitable 0.5V Serial Interface: USB to UART Bridge Adapter (FT2232D chipset series)
PCB/SKD Assembly: Test & Alignment
Pre-Conditions and DC/DC Check
Before power-on, check the board according to the relevant block diagram and circuit diagram, and make sure that no serious issue or mistake can destroy the board. For example, the output of DC/DC and LDO should not be shorted to ground.
Supply a suited voltage and power-on, then check the voltage according to the relevant block diagram, circuit diagram and voltage specification.
For example, check SoC voltage(3V3,1V8, CORE_1V9,5V, 5VSTB, etc.), DDR voltage (DDR_1V5), audio amplifier voltage(12V),etc...
Measurements should fulfill specification within ±5% tolerances.
SW Image download
Download the latest release SW from below FTP server:
- Link: \\10.118.1.66\goc\ (TOT)\ \MT56E1
- Username:None
- Password: None
- Folder: MT56E1
LR or PR step. ---Only test
In case of starting from blanked flash / eMMC, it’s necessary to use “Blank upgrade” to update the SW.
In case of starting from blanked flash, it’s necessary to write “emmc.upm” file via factory copy in advance.
OAD Stream//please delete it ,this mathine did not need this function to update software
To manage quicker mass reflashing on predefined DVB Channel, some licensed IBL tools ('xxx2lli.exe', 'lli2dsm.exe', dsmmerge.exe …) from Intel byte Inc. might be necessary to create appropriate DVB SSU image. Over some predefine settings such as repeated data block insertion, null packets size, … that are controllable in configuration file, here below are mandatory OUI entries structure to prepare DSM-CC carousel image format:
- export CUST_OAD_OUI 0x001C50
- export CUST_OAD_HW_MODEL 0x5395
- export CUST_OAD_HW_VERSION 0x0000
- export CUST_OAD_SW_MODEL 0x0001
- export CUST_OAD_SW_VERSION 0x00‚‚
OAD reflashing is managed within 4 steps operation: multiplex detection, DVB transfer, flashing and warm-start.
How to upgrade FLASH SW and EEPROM Clone using OAD
UART & IR Parser
To use both UART and/or IR parser, TV has to be set in Factory mode with itsUSB port well connected to suitable UART device or an IR emitter device correctly facing up TV (see below “Product Assembly - section 2.0” how to activate “Factory key”).
The UART parser engine is enabled by sending following command “0xE2” from host to TV within following presets 115200/8/n/1.
Once initialized, “PS” caption is toggle displayed on bottom left screen (“S” like Serial).
To communicate with TV depending on SIACP revision layout implementation, you need to fulfill UART/IR commands protocol and format described on enclosed SIACP requirements document.
Project ID Modification
There are different IDs stored into thee MMC depending on different Panels settings and Models features, but there is only one key branching Project ID that includes all. So, it’s not recommended to modify Pane ID with Hyper terminal as other ID features may not change.
To modify Project ID, you need to go through “Factory menu > Other > Project ID”, then spin left or right with RCU “◄/►” key” keys to suitable ID (Project name is dynamically refreshed).It is necessary to press “OK” key for saving the setting.
How to change the Project ID with RCU

Once the boards (chassis, KB, IR, PSU…) and the panel are well interconnected, plug all external generator devices to relevant below inputs/outputs using respective test patterns format to check picture and sound quality.
Audio tones can be defined by the factory (ie: 1KHz & 3KHz, sweep, …).

Picture video formats can be changed by the factory according to their own standard.
As SoC as built-in A/D self-calibration mechanism, there’s not any ADC to perform.
DDC & EDID & T-Link Test
The E-EDID data structures are according to VESA Enhanced EDID 1.3 (and EIA/CEA-861B for HDMI). CEA Timing Extension structure has been extended to support all 3D capable timings.
All HDMI structures have their own BIN profile which are part of main SW and uploaded at power-on into soc chipset: For EDID check, it’s needed to check whether the correct EDID is downloaded by checking corresponding EDID NVM Checksum or read them out to check bit by bit if it is in line with the released EDID bin file.
HDCP Test
For HDCP compliancy, it’s needed to check whether the HDCP key has been well set by connecting suitable generator.
LAN and WLAN Test(MAC address and Device/User ID codes)
Here are some representative codes examples:
Device ID: 6fa0806936a0ada733262a3f8e8595d5586ce5cb
User ID: 111382090
MAC address: 00:1C:50:E2:B1:EC
MAC Address Upgrade (IPv6)
MAC can be set using UART commands described on enclosed SIACP requirements (rev. v3.9).
- Writing MAC command <0xB3>, Data length <6>, Data type <HEXA> (see below command example from above MAC code)
<AA 0B B3 00 1C 50 E2 B1 EC 36 78>
How to upgrade MAC Address using USB
Device ID (DID)
Purpose is to allow Other Newtork Download (OND) and further specific Services via dedicated abroad portal (UK tbc).4 At final, when TV may ask for portal connection, there’ll be Device ID matching control sent by host (TV client) to ensure total integrity.
For such, specific DID (40 bytes) needs to be paired and overwritten into memory for internal client encryption.
All DID and MAC codes have to  download from portal local service via suitable factory workstation LAN system.
Then during production lot, it’s necessary to send/write all those codes to each TV.
DID codes can only be set using UART commands described above on enclosed SIACP requirements (rev. v3.9).
- Writing Device ID command <0xB2>, Data length <32>, Data type <ASCII> (see below command example from above DID code)
<AA 25 B242 45 34 46 32 35 35 42 42 44 31 30 36 42 43 38 46 38 30 36 41 45 34 35 36 33 35 30 44 39 31 464893>
LAN Test
A rough LAN test can be done by connecting DHCP server to TV’s RJ45 and check that IP, subnet mask, DNS, … addresses are visible on “User menu > Network > Internet connection(On) > IP settings”.
More in-depth test can be performed faster using suitable UART/IR commands following SIACP requirements. SW will internally manage Network ID (NID) flag controlling all MAC/DID/UID integrity to facilitate PA screening further.
Factory Menu

Main SW Ver
FRC Ver(MEMC version)
Project ID(ID)
ERG(PVR)
CI Key Activation flag (CI+ key)
NID(Internet in for factory)
P (Production/Factory mode flag) / S (Factory UART Parser mode flag) / W (Warm-Up mode flag)
Following TCL standard and practices, it’s required minimum 15min of Warm-Up that can be considered as Burn-In.
Additional Aging for White Balance alignment is no more necessary due to consistent Picture Performance with Cloning usage.
This function is accessible by selecting “Factory menu > WARM UP”, pressing RCU “OK/►” key and then leaving Factory menu by pressing “Exit” key. To release/disable Burn-in mode, it’s just required to press “Menu” button from local keyboard. Other faster methods via UART/IR commands are available on enclosed SIACP requirements (rev. v5.4)
White Balance Touch-Up (Golden sample)
As some color coordinates discrepancies can be noticed from panel batches to others, it may necessary to perform slight touch-up.
For Color temperature adjustment, switch TV on leading HDMIinput where should be connected suitable generator providing following format 1280x720p@60Hz test pattern. A 32 steps grey scale is recommended to assess relevant colorimetry tracking and low/high light saturation points.
Ensure that TV’s picture enhance is off.
Ensure that TV is in Factory mode to access to ”White Balance” adjustment submenu, then scroll down to toggle off “Pic. Enhance” flag.
WB Normal is the first mode which is adjusted in HDMI source, the next are HDMI warm and cool mode.
Warm and Cool Tone are relatives to Normal mode.WB adjust need to fix default G Gain .Offset registers needn’t to be adjusted.
“Gain” registers set need to be adjusted at 70IRE
Test and Alignment Specification for MT56EP1 Series (v0 01) 160825.docx
Targets and Tolerances for all inputs. (According to company uniform LED color temperature standard of panel)
The measured and adjustable parameters should be mainly “x”, “y” coordinates.
The White Balance alignment should be performed using a well calibrated and contact less analyser (ex: Minolta CA210 or CA310). The analyzer may not touch the screen surface, and measurement must be performed in a dark environment keeping the probe(s) at 90+/-2° from the panel center.
The results should fulfill specification for each TV set.
Important: If measurements are performed on whatever else LED panel with Minolta CA210, it’s required to calibrate additional channel (ex: CH01) using relative following offsets (CH00 remains for CCFL panel):+0.002for “x” and +0.012 for“y”.Cloning
Once a TV is well aligned and prepared (channels maps, volume, picture presets, …) , user can prepare golden clone image that can be copied on demand to all further TV production lot of same TV. To access cloning function, you can select “Factory menu > USB Clone &&Update > All Clone/CH Clone/User data Clone” , Scroll down to “TV to USB” or “USB to TV” and press RCU “OK/►” key to process.
4 BIN images can created, overwritten or read on USB stick (pen drive) depending on chosen template like following: “database\applications\database\***.db” . These files
need to be used strictly with NT667SoC platform as depending on SW structure.
Other faster access methods via UART/IR commandsare available on enclosed SIACP requirements (rev. v3.9).
SHOP-END Test
At final process stage, it’s necessary to perform“Reset shop” before any packing to leave Factory mode and restore User default presets.
This function is accessible by selecting “Factory menu > Reset Shop”, then pressing RCU “OK/►” key. Other faster methods via UART/IR commands are available on enclosed SIACP requirements (rev. v5.4).

The auto-configuring sharing device cannot be connected to automatically through a wireless dongle.  (Here, the user’s sharing device must support auto-configuration.)
1. Check if the sharing device of the user supports auto configuration.
2. If the sharing device of the user supports auto configuration, place the sharing device as close as possible to the wireless dongle on the TV and try to re-establish the connection. (Must be placed close to the TV to establish a connection.)
Cannot connect to a wireless network (2) or AP
* There could be several causes of the connection failure. Check the AP settings to see if the following condition is found.
* The Pure high-Throughput 802.11n mode (or Greenfield 802.11n mode) is selected and the Encryption type is set to WEP, TKIP or TKIP-AES. • Under the conditions stated above, Samsung TVs will not support a connection in compliance with new Wi-Fi certification specifications. This is intended to maximize the performance of the AP, TV and TV network.  To connect to the AP, set the Encryption type to AES. If Pure High-Throughput 802.11n mode (or Greenfield 802.11n mode) is selected and the Encryption type is set to AES, your Samsung TV will connect to the AP providing you with optimum
performance.
Although the TV is placed close to the AP and the dongle is inserted into the TV, the sharing device cannot be connected to using auto-configuration.
Select [Menu] > [Setup] > [Network] and check if SWL is Off.
If the AP is turned off, the TV will try to re-establish a connection for 2 minutes.
Although the TV is placed close to the AP and the dongle is inserted into the TV, the sharing device cannot be connected to using auto-configuration and a message that it is connecting is displayed only
Check if the AP is not turned off during connection.  If the AP is turned off, the TV will try to re-establish a connection for 2 minutes.
In order to use the Samsung Auto Configuration function, I did as the user manual instructed. I get a message that connecting to an external network has failed
The Samsung Auto Configuration feature is designed to establish an auto connection between the TV and the gateway of the AP. It performs a connection test if the AP is connected to an external network.
If the AP is not connected to an external network, a message that establishing a connection to an external network has failed is displayed. In this case, connect the AP to an external network. After a connection to the external network is established through a network test, you can use the network without any problem. Check if the AP is connected to an external network.  If you perform a test when a connection to an external network is established through a LAN cable, you will obtain successful test results.
When SWL is On,  cannot connect to the 5GHz Wi-Fi mobile device
SWL is connected to a Wi-Fi mobile device which uses 2.4GHz bandwidth and supports PBC (Push Button Configuration) mode.  A mobile device which uses 5GHz or 2.4GHz bandwidth but does not support PBC cannot be connected to the TV.
* WPS: WPS is the acronym for Wi-Fi Protected Setup, and includes two types: PBC (Push Button Configuration) type which performs cross certification with the press of a button and PIN type which performs cross certification when a PIN (Personal Identification Number) code is entered.
Although the TV is placed close to the AP and the dongle is inserted into the TV, the sharing device cannot be connected to using auto-configuration and a message that it is connecting is displayed only.
* If Samsung Wireless Link is On, a 5G-bandwidth wireless sharing device may not be found in a search (restriction).
* If Samsung Wireless Link is Off or the product does not have the Samsung Wireless Link function, please retry searching to fid the sharing device. (May not be found in a search depending on the settings of the wireless connection.)
In a network test over a wireless connection, the second items which include the IP address, subnet, gateway and DNS server fail
*If the IP address, subnet mask and gateway were typed in manually, check that valid values were entered. (For example, 0.0.0.0 is not valid for an IP address, subnet mask or gateway address.)
* If the IP address the user entered in is invalid, change it to a valid IP address.
In a network test over a wireless connection, the third item, gateway ping fails.
1. If the IP address is automatic and connected to a sharing device, check the settings of the sharing device (AP) that is using a cable connection, or consult the corresponding Internet service provider.
2. If the IP address is manual, check that the IP address is entered in correctly. (Here, the user should confirm if the manual IP entered in is valid.)
In a network test over a wireless connection, the fourth item, Internet service test fails.
Consult the corresponding Internet service provider (an Internet network service provider the user has subscribed to such as KT)
