I have a 2001, Panasonic 27


Suspect either bad solder connections somewhere or a issue in the power supply of the set----set will shut down for a number of reasons--it monitors voltages inside and if some go high or low it will shut down.

The tv keeps shutting off just after minutes of turning it on. We can wait about 5-10 min before turning it on again but then it only stays on for a few minutes.


This sounds like a heat related problem, which could be a faulty chip or a cold (bad) solder joint on one of the PCBs (printed circuit boards). Due to the lethal voltages present inside a CRT type television, it is strongly advised to have this repaired by a qualified technician. however, if you or someone you know is technically inclined, you can try to fix this yourself. Cold solder joints can often be spotted by visible cracks in the solder joints. a through inspection of all the boards could easily identify the problem which can be resolved with a quick tap with a soldering iron and perhaps a little extra solder added to the joint. if that yields nothing, another method is heat/cold stressing the boards while the TV is running. With the TV on, spray small areas of the PCBs with cold spray (or a can of compressed air duster turned upside down) until the tv shuts off. then heat the last sprayed part with a hot air gun (or a hair dryer) until you can get the problem to repeat regularly. inspect the area causing the problem and you will probably find the culprit.

TV shuts off on it's own. Turns on fine, stays on for a few minutes, then something clicks inside, and it shuts off, and can't be turned on with remote. I then spend the next 5-10 min turning it back on...


This is because of a power supply unit going out inside and there is not much you can do accept for have it repaired or think about new at this point also with the new digital tv standars comming out you are going to need a box for this if you doing OTA anyways so at this point if you are not inclided to haing it repaired have it recycled.

Intermittent shut off


20 years is too long and the components ternmial might be loose or crack at this time, I'll susgest you look for any dry cold solder on the main board and do resoldering to the components terminal.

Philips/Magnavox TV, model MS3250C321 shuts off randomly.


TV shutting off automatically means its a problem with the Lamp. Contact Pioneer or any local tech shop or Best buy and get the same replaced.
Turning off after specific time : Go to the timer option and disable the Automatically Switch off option. This will resolve the issue. Please let me know if it worked. If you need the user manual or instruction manula please click on the link below
