Entertainment Center: TVs, Stereos, VCRs and DVDs - Hitachi TV kaput

Hi,

I was watching the Chargers and 49er's play today and my Hitachi 35TX30B 35" tube TV decided it had enough. :(

Basically, the symptoms are that I lost video and audio. The main relay clicks when you attempt to turn on the set, but it seems that the high voltage and low voltage supplies never comes up. I opened the back and checked the fuses, only found one where the power cord is connected to the PCB and it is good.

Have had the TV for 7 years... seems kinda early for it to go, but I also don't want to spend an arm and a leg to have it repaired. I'm, elecrically inclined and have all kinds of test equip... ,

What do you all think?
1. buy a service manual and spend some time troubleshooting

2. call the TV repair guy

3. say goodnight and go get a new widescreen?

Any suggestions?

Thanks!

Doesn't sound too major for that size set, still worth repairing - check or replace Q901, IC901, and R908.

Thanks, XperT PC, checked them and they look ok. Found another regulator that was bad, it is the one before the HV P.S.
