Re: LG OLED 55EC930V Horizontal flashing lines problems
What I found, is the new TCON and the old TCON eMMC contains almost same data, comparison was not easy, but data on the original is shifted up, it means the memory controller inside the eMMC is the real problem, it allocates memory in a bad way. So is IMHO impossible to recover original panel compensation and copy it, because part of the data are outside visible range coz badly allocated by the eMMC. Is clearly a Micron eMMC problem due to a bad chip sorting during production. What is "funny" is that piece costs only 4$ but makes a 2.5K TV unusable. So the only way is to replace completely the TCON but since the TCONs we found on ebay, are taken from shorted/broken panel TVs, the FPGA chip can be also partially faulty, this is why we get large vertical bands. The only way in my opinion is to resolder OLD TCON to the new TCON board. But we never get back the original calibration, we will always see halos somewhere. If we can access the eMMC memory maybe LG stored somewhere during production, it will be easier, but I don't really think it will be possible.
