Toshiba 26EL933B

[Sandokan]

Good morning!
I have this Toshiba 26EL933B that won't stay on for longer than a minute.

What could I be looking at?

Hello Sandokan and welcome to the community.

Locate the two transistors Q303 and Q304 on the power supply board and after removing the glue that covers them, resolder the transistors.
Also check Q301 and Q302.

Tell us how it went!
