Swap tcon Hisense 55p7 65r7

Hi, can I use a tcon from 65”tv in 55”? The model is different obviously but am curious as to what could go wrong. My tv was flickering and so far I changed a power board and main board from a newer model (which works fine by the way) but it still flickers after an hour of watching. So the only part left is Tcon :)

Thanks for answers

@anitak71969 if all the connections match, yes you can use it. However, at times the boards have an EEPROM IC that is programmed for the different TV. You may have some disturbance or picture issue. If the electrical connection is identical, you can at least give it a try. looks like your 55" model is a 50T32-C0D TX-5555T32C34 board and your 65" is a 55T36-C04 TT-5565T50C34 Let's see if we find out more information about compatibility.

Anyhow, the flickering can also be caused by the panel and bad ribbon cables. You do want to check those as well.

Thanks @oldturkey03, you are the best. Connections are the same for both Tcons. I will definitely check the ribbons as well. I salvaged everything from 65r7 so it should work. And if it's the panel I don't think I can do anything about it. Replacing seems to be too expensive.


@anitak71969 when you check the T-Con board, take a simple look at the lines going to the connectors. the thicker ones are usually power lines and the smaller ones, datalines. Make sure that those look about the same for both boards. You can always try a tape-off if it is the panel. Not 100% but it gives you something like a 75-80% chance of fixing it. At least temporarily. Best of luck with your repairs. Remember this ;-)
