I have been seeing universal android boards is but the ones I have been seeing have their own psu and tv remote is there an android board made specifically for this tv I can't seem to find anything online...

I had taken it to a repair shop they said it wasn't worth fixing so I tried repairing it and it lead me to the fusion chip so I did it as one last effort and the tv worked for a bit

After heating it up again I have a solid red light no 12v. The fusion chip is the problem does anyone know if there are replacement motherboard available in cant find any.

I think I am going to throw it out I have been trying to repair it for a few days.
I might just try the hairdryer again before throwing it in the trash because I can't find a replacement motherboard online

No I only have basic tools just a multimeter and a soldering iron

Do you think the cpu is still good the first time I heated it with a hairdryer for 5minutes straight and it fixed it but when it stopped working again I tried it again and it didn't work. The first time I had an error code and the 12v lines where all active now the 12v lines deactivate....

I was trying to repair my tv wich previously had a blinking red led 2 times and it kept going. After shorting the sdm the blinking led changed 5 slow blinks and 3 fast ones wich in the service manual meant error 53 / the fusion chip.
After I heated the fusion chip with a hairdryer for 5 minutes it started working perfectly but after a day it stopped this time no led blinks even in sdm mode.
After probing the psu I have 3.49v and for 1 second I have at least 2 12.3v lines active the fusion chip gets warm in that second the led turns on and then the 12v lines start losing power...
