Came back from vacation and tv would not turn on either by remote or on button. Nothing comes on. Unplugged for thirty minutes and still nothing. Power cord and fuse are okay. Don't have wiring diagram but suspect power supply. TV is 12 years old but worked fine.

Any suggestions to test myself with a multimeter as repairman wants $100 to check it out in home?

Dead set. Suspest U3200 eeprom, Q4401 horizontal output (2SD1885), C4401,C4402, CR4401, and CR4402.

So first thing see if q4401 is shorted and go from there.
