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!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

LG 42LG60FR - 42LG60FR-MA - 42LG64FR HOW TO DOWNLOAD AND UPGRADE SOFTWARE

HOW TO DOWNLOAD AND UPGRADE SOFTWARE - ADC Process - LG 42LG60FR - 42LG60FR-MA - 42LG64FR

S/W UPGRADE
  • Because this is not a hot chassis, it is not necessary to use an isolation transformer. However, the use of isolation transformer will help protect test instrument.
  • Adjustment must be done in the correct order.
  • The adjustment must be performed in the circumstance of 25±5°C of temperature and 65±10% of relative humidity if there is no specific designation.
  • The input voltage of the receiver must keep 100~220V, 50/60Hz.
  • Before adjustment, execute Heat-Run for 15 minutes at RF no signal.
Adjustment items
PCB assembly adjustment items
Download the MSTAR main software (IC801, Mstar ISP Utility)
SET assembly adjustment items
DDC Data input.
Adjustment of White Balance.
Factoring Option Data input.
PCB assembly adjustment method. (Using MSTAR Download program)
S/W program download
Preliminary steps
Download method 1 (PCB Assy) – HD
FHD
  • Connect the download jig to D-sub jack.
  • Execute ‘ISP Tool’ program in PC, then a main window will be opened.
  • Click the connect button and confirm "Dialog Box"

Click the Config button and Change speed E2PROM Device setting : over the 350Khz.
Read and write bin file.  Click "(1)Read" tab, and then load download file(XXXX.bin) by clicking "Read".
  • Click "Auto(2)" tab and set as below
  • click "Run(3)".
  • After downloading, check "OK(4)" message.

USB DOWNLOAD
  • Put the USB Stick to the USB socket.
  • Automatically detecting update file in USB Stick.
Select "Start" Button and press "OK" button Updating is staring.
Finishing the version updating, you have to put out USB stick and "AC Power" off
After putting "AC Power" on and check updated version on your TV.
ADC Process
Required Equipments
  • Remote controller for adjustment
  • MSPG-925F Pattern Generator
Method of Auto RGB Color Balance
  • Convert to RGB PC in Input-source
  • Input the PC 1024x768 @ 60Hz 1/2 Black & White
  • Pattern (MSPG-925F model:60, pattern:54) into RGB.

Adjust by commanding AUTO_COLOR_ADJUST(0xF1) 0x00 0x02 instruction.
Confirmation
  • Confirm whether "0xF3 (offset), 0xF4 (gain)" address of EEPROM "0xBC" is "0xAA" or not.
  • If "0xF3", "0xF4" address of EEPROM "0xBC" isn’t "0xAA", adjust once more
  • We can confirm the ADC values from "0x06~0x0B"addresses in a page "0xBC"
Manual ADC process using Service Remocon.
After enter Service Mode by pushing "ADJ" key, execute "Auto-RGB" by pushing "_" key at "Auto-RGB"
Component input ADC.  Component Gain/Offset Adjustment7
  • Convert to Component in Input-source
