The bad cap plague appears to match the symptom.
But here's where it gets hairy. If the device is left in service the symptom will eventually cause more damage and a 20 bucks in parts balloons to more than the set is worth.
And let's be very clear here. ALWAYS call it in as some makers do not want to spend time in court over such a well publicized plague.
Upon clicking the TV on button, the power on blinks and it may be anywhere from 1 minute to 20 minutes or so before the set turns on. This has been happening for several weeks. Now it does not turn on at all. It seems that the problem is probably in the high voltage circuit, possibly the capacitor. The set is about three years old. Would it seem feasible to have the set repaired or to just look at buying a new set?
Thanks for your help or advise.
