Hello, as in the subject of tv, there is only the startup logo. Main LC / LD LE42B, 42G EAX65384004 (1.5) EBT63439306. Has anyone grasped this topic, or just a disc replacement. I would ask for help.

Replace EEPROM IC103 with blank memory chip then carry out a reset.

Unless the EMCC is damaged, it can be repaired this way, of course you need the correct EMCC charge

Well, what's up, buddy @ repair tv ? A week has passed, he received a few hints, used it? How to repair described? Added after 3 [minutes]: The author of the topic is not active, so let's discuss. Is there any way to check this?

If the memory can be read, it should not be damaged. To be sure, this can be done several times and compared. Then program the batch from a working donor and test if there are no problems with HDCP keys, internet, CAM module, etc.

The memory is readable, but it may not be writable, preferably a new one that has already been programmed and the problem will not return.

1) Why not give it a try, maybe it's still possible to save 2) Where to get the programmed? 3) Who would like to upload an incorrect batch? 4) Maybe a new TV set right away?

1 You can try, the TV gets up after that but not all 2 Program a new EMCC in the programmer (unless there is a problem with the lack of a programmer, adapters for programming the memory and new EMCC memory, this EMCC type occurs in many other TV models, so it is worth having them in stock) 3 If it is correctly matched with a working TV, no problem 4 You can buy new best 4K and EMCC memories on board .

Is it impossible to block reading this memory on startup so that the system would even start? I read somewhere about applying the Vcc signal or ground to the SDA bus.

1 You can try, the TV gets up after that but not all
2 Program a new EMCC in the programmer (unless there is a problem with the lack of a programmer, adapters for programming the memory and new EMCC memory, this EMCC type occurs in many other TV models, so it is worth having them in stock)
3 If it is correctly matched with a working TV, no problem
4 You can buy new best 4K and EMCC memories on board .

Is it impossible to block reading this memory on startup so that the system would even start? I read somewhere about applying the Vcc signal or ground to the SDA bus.

Pretty good idea, you have to try it out!

I erase the eeprom ic103 with a programmer but it don't work

Dodano po 6 [minuty]:

Hi Adewag. You don't describe very well the VCC and the VCCQ

It's Ok GanCegall. We don't need the VCCQ. And the problem with Eeprom is that, when I erase the IC, nothing changed
