AFTER AN HOUR OR SO THE TV SHUTS OFF AND RED LIGHT FLASHES.IT WILL DO THIS SEVERAL TIMES THEN IT TURNS ON AND WORKS FINE FOR AWHILE THEN DOES IT ALL OVER AGAIN.IF I LEAVE UNPLUGGEDFOR A DAYPLUG IT IN THEN ITWORKS FINE FOR AWHILE AND GOES THROUGH THE WHOLE PROBLEM AGAIN.
If you are a electronics engineer, then check the smps +b voltage that is around 140volts for 27"t.v if is low or high then check electrolytic capacitors in the smps circuit and change the same ratings for continuid saftey, if +b voltage is ok then check the backside of E.H.T a small electrolytic cap rated 10micro 50volts for feedback replace it .

check all caps in the power supply especially the 10mf 22vols cap.the caps are not filtering the voltage properly when the the current i off the caps drain the voltage and does not keep charging.until when current is applied to the set.good luck.
get a memory stick( flash drive) and up load their soft ware from their
site. I plug the stick into the computor and uploaded the software.
I then plugged the stick into my TV on the side. A screen came up and
the software loaded on the TV successfully. The red light then turned
to green. However, I now have to unplug and plug the TV several times
for it to turn on. It works fine but once the TV is turns on, but when
I turn it off and it cools for a while I have to repeat the same
proceedure off plugging and unplugging
Generally these type of problem occurs due to atmosphere contains moisture content. Even if it happens in warm area i suspect fbt leakage. Since this is high voltage transformer it can be serviced by qualified technicians only. Red light flashes indicates the tv in protection mode to avoid severe damage due to some short circuit. I think it is helpful to you
This unit shouldb e flashing a repeated count on the standby light. That count will indicate the circuit in which a problem was detected causig the shutdown. Please post that count and we should be able to provide details on the repair.
capacitor problems in power supply or a regulater isolate the power suppley by disconecting the line output stage/unplug scan coils for example and run a 60w bulb as a dummy load one wire to earth and the other to rail voltage colecter of line output transister if the bulb glows steady the power supplys fine
Same problem. The power button does not work. The volume and channel buttons turn the tv on. the tv then shuts its self off 15 seconds later. the red light blinks in second intervals while this happens.
