TV would not power up back around Christmas. Unplugged it and let it set over night and it powered up and run for a while. Put it in the shop and after the run around i got it home to fix it myself.

I took the back off the other night and hooked up a game and turned the kids loose on it and it played fine then I left it powered up that night to get up to it shutdown and will not power up.

Unplug it and let it set and it fine for a little while.

I cleaned both of the fans really good vacuumed the dirt out of fans and around where the fans are.

It acts like it is tripping a circuit breaker and then it resets itself after it is unplugged for a while.

well, it sounds like there is something in the eeprom keeping it from starting up. Either it is finding a fault, and purposely keeping it off. Or it is faulty and cutting power to it eventually causes the eeprom to reset itself.

I can't remember off my head how to get to the service menu for certain but see if this works:
power off the set for 10 sec, then hold down Vol- and Ch- buttons for 10 sec

If that gets you to the service menu, you can check the error/fault codes.

If it doesn't, post back and I will look up the correct service mode procedure.

Will this still work even though I am having to unplug and let it set for about 24 hours before trying?

Just to make sure I understand you.

I turn on TV
Then turn off TV wait 10 secs
then hold both the Channel (-) and the Volume (-) for 10 secs

And then the screen will come one? and be in Sevice Menu?

Yes, the fault will be recorded permanently until reset.

and yes that is the procedure

I tried to get it in the service menu and it does go in to it.

Are you sure that is right?
Please Let me know I unplugged it again to keep it from holding a charge and shutting down again.

Been to ever site i can find but i need to know what the eeprom is holding in the service menu that is powering my tv down and keeping it down.\\

Any info on service codes?

I can't find anything on those error codes. I have never needed to purchase the service manual for a CTC211. So I can't tell you what they mean. You can purchase a service manual from http://www.thomsonnetwork.com/. It looks like it about $40.

If it were in my shop, I have a chipper checker I would use to read those error codes. But I know that doesn't help you much.

At this point, unless you can find a place that will tell you what those error codes mean, I would try checking the voltages to see if they match up with the ones in that link I gave your previously.

I suspect you have a fault with the High Voltage... either in one of your CRTs or the flyback xfmr or splitter. It's just a guess at this point. Because I don't know what other fault would cause the TV to shut down for good. I wouldn't jump to that conclusion without a little more info.

I'd still like to hear what the service shop has told you.
