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.

SANYO LCD 47XR2 SMPS SCHEMATIC, FACTORY MODE, SOFTWARE UPDATE

LCD 


1 682 342 81 : AUS, SS etc. 
1 682 343 78 : INDIA

Method of software upgrading
Steps of software upgrading are as follows
1. Select a serial connection wire and a VGA connection wire and then connect them by means of a patch panel;
2. Use a serial wire to connect the PC to the patch panel and set TV set to off state; Open the software upgrade file folder and double click FlashUpgrader.exe (window 2000/XP/NT)
The following interfaces will show up after running the program.
Based on the computer features, set up the serial port (COM Port). 
Select corresponding serial port (if it’s unable to FLASH WRITE, change to another port). 
Baud is selected to be 115200. 
Then select Reset Target After Download. 
Click FLASH push-button, it’s ready to run. 
For other settings, please refer to the Fig. Above (already defaulted by the system, normally no need to change).
Switch on TV set the FLASH write program begins to run;
When the upgrading is complete, a window (below) will be opened. 
Press “Finish” button to complete the process.
Note: Do not shut the power off or turn the TV set on during the FLASH write. Otherwise it may lead to no way for flash to rewrite.
To Enter the factory menu  press 1→ 9 → 7 →9 button in the window menu state.
The unit has two MCU, the main MCU is PW218 (N601): it is used to control all the chips’ working status on the main board (including image processing, channel switch, sound processing, image display etc.), sub CPU, OSD, searching channels, image effect adjustment, buttons control, infrared remote control etc.; the sub CPU is ATMEGA8L (N606): it is used to control power supply, including standby and turning on the unit by using remote control etc.. The two MCU correlates with each other through pin 14 INT (interruption) of ATMEGA8L, pin 28 and 29 SDA, SCL.
The unit has one integrative tuner (including HF and IF amp. circuits). 
The signal received by antenna is sent to tuner, under the control of MCU PW218 (N601) SDA and SCL, proper channel selection and right system switching will be done by the tuner, then video signal and audio signal will be output by the tuner through decoding and by high and intermediate amplification. Video signal of the tuner will then be sent to Decoder PW2300 (N201). Audio signal of the tuner will then be sent to AV switch box M52797 (N400), the audio signal of AV1, AV2 and HD2 of the main board will also be sent to M52797 (N400) at the same time. The selected audio signal after switching will be sent to R2S15900 (N301), and then switching selection will be done towards the above audio signal together with the audio signal of VGA, HDMI and HD1. The two chips are controlled by PW218 (N601), after the above process the finally selected way will be set to X300 earphone socket after under the control of volume, treble and bass which is finished by R2S15900 (N301), the earphone socket has the switching function, when earphone is plugged, sound will be sent to earphone amplifier NJW1109 (N302), then sent back to earphone socket after power amplification.
If earphone is unplugged, sound will be sent to sound amplifier TPA3008 to do amplification and then sent to speaker.
Image parts:
Video signal of the tuner will be sent to AV switch box M52797 (N400), video signal of AV1 and AV2 will also be sent to M52797 (N400) at the same time, two groups of video output will be obtained after switching, one group of video output together with its audio output will be sent to AV_OUT terminal to treat as AV OUT. The other group of video output together with other video signals such as S-VIDEO, YpbPr1, YpbPr2 and VGA will be sent to PW2300 to do video decoding or AD transformation, then output 24bit digital RGB signal and some corresponding synchronous signals.
Items such as 3D comb filter, channel switching, 5 lines Y/C separation and color decoding etc. are primarily done by PW2300. 24bit digital RGB signal and some corresponding synchronous signals outputted by PW2300 will then be sent to PW218 (N601). HDMI signal will also be sent to AD9398 (N101) to de decode and output 24bit digital RGB signal as well as some corresponding synchronous signal, which will be sent to PW218 (N601). 
PW218 is a new generation chip of Pixelworks, which has ability to deal with images, 24bit digital RGB signal and some corresponding synchronous signals outputted by AD9398 and PW2300 will be sent to this chip to deal with images.
The chip has functions such as converting from interleaved into line-by-line and image enhancement etc.. PW218 has SCALER function which can do format conversion towards different input formats so as to meet the format needs of the screen and finally output 24bit RGB signal. The interface standard of PDP screen is generally LVDS (low voltage differential signal), so the digital RGB signal outputted from PW218 is needed to send to converting interface chip N6 DS90C387 of LVDS to obtain LVDS signal, then it will be sent to the screen. PW218 is also the main CPU, its programs are stored in periphery device flash N701, and software upgrade through RS-232 interface is virtually upgrading the stored programs through PW218 towards N701.
High definition 1080P LCD
