You need to lay out your own dump, it will not work with strangers.

Because you didn't set and write the status register (0x88, 0x42) after dump was written.

Yes its now working, thanks a lot!

With a huge delay, may I have detailed instructions. I have located the Chip on the main board. Should chip get removed? ]How to connect the mainboard 8 pin chip to CH341A hardware? I guess USB goes to Laptop and software?

Try this one, but the problem may also be in the 25Q80 firmware, which is responsible for the panel and t-con settings. Are the motherboard and panel part of the original kit?

[serkan koc]

bunu deneyeceğim.. evet panel ve anakart orjinal.. t-con anakart üzerinde. anakart ve panel modelini ekliyorum.
