Alright can anyone help me out I have a cheapo tcl 65 in tv where the picture cut out. The backlight still comes on and works I have sound I can here it able to click through the menus the picture just cut out. I read online that it’s the t con board so I replaced that and no dice so I figure I’d replace the main board and power supply and that DID work for about 5 min I had it all laid out the screen came back on I was like sweet I fixed it then I hung it back on the wall turned it on it came on for a few seconds flickered and went out again I don’t know if the means I just have a short somewhere or if I fried my new parts I just put in or what I’m kinda at a road block here. Can anyone help me? Update (06/30/2022) The first picture is just the screen directly after replacing all the boards when it worked for 5 min
Update (06/30/2022) This is the main board i replaced i have it plugged in just so you can see the backlights
Update (06/30/2022) Power supply
Update (06/30/2022) T con board
Update (06/30/2022) Full layout the inside isnt as dirty as it looks in the picture either but there is some dust
@dakblack my biggest concern with that is that you said the backlight comes on. You do want to verify this for us. Make sure that you can see it with the back cover removed and through the many holes in the sheet metal for the panel. TCL is one of those that uses inferior backlight strips. As it stands and you already having replaced all the boards there is only a few possibilities eft, like a bad panel could be one of those, which would not be good. Double check the work, all of your ribbon cables etc. Post some good pictures of all of the boards as well as the interconnect cables etc. Let’ s see what we can determine without any schematic (unavailable) but double check on the backlights.
