Like quite a few other people on this site, I have the TV turning itself off, with the flashing red light business. We always turn the TV off completely, never leaving it on standby. When it's been left turned off for a long time, eg overnight, the next day it behaves itself, operating with no problem. But, if it's turned off and then turned on again a short time later, say half an hour to an hour, it starts this turning itself off business. Does this put a new spin on things? Also, as one of your members has said, if the number of times the red light flashes is a code meaning something, can he give us a list of the different codes' meanings, please? Thanks, John.
John, I do not know of a code, but it is a good idea in the design to have several goes at starting a circuit, before completely shutting it down. Oscillators are supposed to self start due to noise generated. Some electronic circuits require a reset pulse to be generated before the start up is allowed. The reset circuit may not be generated if the set is turned on again too soon, so it will stay in standby. This may normally be a few minutes to 30 minutes so it seems something in your set is faulty and could get worse. Try a test run with the back off and clean it out of dust with a long brush to keep it cooler. Make sure little fingers cannot get near it. Look to see if anything is obviously overheating.

Yes my problem is precisely the same, i have removed the cover and brushed it down, even used a vacuum cleaner, but when i switch it on, 5 minutes later it goes off, i did not notice that anything was over heating. when i let cut the power to the TV for approximately 1/2 hour and power up again, i may get max. 15 minutes of viewing.
yes but with a diffrent model tv happened with a 32" widescreen - 32wr250 this has happen on two seperate tvs the first one i managed to claim on my insurance
likewise, problem with the flashing lights and not coming out of stand by. flashes 2x then 7x then repeats 3x and won't turn back on...really fustrating. Is it easier to just replace the set, or is there a quick repair for someone that knows nothing about the inner workings.!
cheers
