While watching TV it turned itself off and now won't turn back on.?? I can't tell if the tube blew or if it's something else. But given what it would cost to have the TV serviced as well as the continually dropping prices on new HDTV sets I wonder if it's even worth fixing? Any advice out there? Thank you.
Just a comment to clarify "everything is going HD next year".
Next year ('09) Broadcast television is moving to new digital channels from current analog postions. This move means older TV's will only work if your on a cable system. If your on an antenna, you can purchase a low cost "Converter Box" that will keep your set working in '09 and beyond.
This has nothing to do with HD. There is no mandate for Broadcasters to transmit an HD signal. It is purely a business decision each Broadcasters will make. Digital does not mean HD.

you can open the back of the tv and see if it blew the fuse but watch out for the flyback anoid it still holds power if you don't know what that is it the thick red wire that plugs into yhe tube so DON'T UNPLUG IT FROM THE TUBE you will get a big charge and the fuse should be near the flyback and if it still dosen't work the the output IC is probley fried.
I think it is the EHT for some reason it blew off for you. You got a miniature picture after you turned it on again because it was partially damaged and then it blew off completely. It can be fixed from a competent person.
If the tv has nothing happening at all when you try and turn it back on including any noise, your power supply is broken. If it is still trying to turn on or does make noise, an internal component has come loose or been knocked off, most likely to your picture tube.
Picture tubes rarely go bad. You have a bad connection or something on the circuit board that is breaking down due to the temperature change . Probably an easy fix. Not something an unqualified person can do though. Your local shop should fix this for about $60-100.
Yes - a new more expensive TV that is not a throw-away model.
The problem is probably in the micro and will continue this intermittently - sometimes hot/cold can have an effect on when it has the problem. It will get worse and it will eventually need to be repaired...
Sorry for the bad news.
If your TV is the type that has a picture tube,the picture tube itself could have gone bad. Also one of the picture tube driver circuits may have messed up. A number of things can cause this to happen. You'd need to
take it to a shop and get an estimate for repairs.
Hopefully you can find a shop that will give you a free estimate.
If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages.
Could be several things- a 15 cent fuse, some solder joints that fail due to expansion and contraction of the circuit boards. Hard to say.
Look for parts that look or smell burnt, might help you narrow it down.
The fact that it stopped suddenly, with no gradual deterioration makes me think that something blew, and it's a matter of replacing it. No tube damage or anything more serious, just a local fuse or cap.
