Only 3/4 of the LCD turn on... if I unplug one of the "LCD" strip
My TV (TCL 65S434-CA) turn on and has backlight, but didn't have any images. After opening it, I discover that if I disconnect one of the output from the main board, it was displaying half of the image.
So I repluged the cable and disconnected the joint between the first and last strip (not sure of the name, but they are connected directly to the LCD, I think they are t-con?)... now I got 3/4 of the LCD working.
Now I'm wondering if it's the strip or the mainboard. What can I do to find if it's the case? I've tried to reverse both end, but it dosent work as I think the connector are reversed. So green with green and red with red work (whatever the cable I'm using), but green to red or red to green dosent work.
@oldturkey03 Did a quick search and could not find anything search for "tv tape off" or whatever, Google give me way to remove tape residue or tape car before painting and stuff like this... but I guess it's taping the pin to find what pin is cause the problem? I will try that tonight. Already did that before, just didn't think about it this time! Thanks for the suggestion!
I did take some pictures near the connector (quick before going to work), but I was not sure what I was supposed to take : https://photos.app.goo.gl/gKiUUdLBaajkKb...
I will probe the first few pin labeled as CDX near FPC 0129 on the main board to see which one are going to the secondary left driver board and tape those, then remove tape until I find the one causing the problem, hoping this fix will be "good enough".
Thanks a lot for your help!
