Have a good day! I really liked your article on repair. Thank you!
I changed faulty transistors to Y, changed the dried-up thermal interface. TV came to life.
But transistors Q707, Q708 heat up around 85C. According to your experience, I want to add a cooler for cooling. I understand that a lot of time has passed, but can you tell me how to connect an additional cooler?
Thank you very much!

Well done and thank you for sharing, this helps me a lot.
I have the same tv, i repaired the ysus board, the tv starts but with black screen.
Tcon LED is off, there is no 18v comming from zsus board to tcon board, and there is no outpout from ysus board to the buffer ICs.
I tested Q9 and Q10 in the zsus board and they was ok
Do you have any advice that help me, please?
