Television played fine, even after recently adding cablevision. You can see the green light & hear it turn on, it will have sound for 1- 3 seconds, then the audio stops and the green light blinks 3 times, 2 times, then 1 time. It does this sequence for three times then it turns off. What can I do?

Re: won't stay on
RCA TVs do this when they detect an overvoltage condition on startup. The reason they shut down is to prevent x-ray issues. If your set is having this problem there is a problem in the x-ray detection circuit or it is not regulating the high voltage. Either way you will probably need to take it to a professional as it would beyond your capabilities to fix it.

It sounds to be a panel fault. Contact any service technician, and make it sure. If you wish to get some screen-shots about faulty displays http://electronicshelponline.blogspot.com/ check this link. Pull up previous posts there, either by its left side bar,

i am having the same problem. My Phillips 37" 37PF9431D/37I LCD High Definition TV won;t turn on. When I press the power button i hear a click and the green light comes on for a couple of seconds and then the red light appears. I can;t figure it out. Did you find a solution?
The power supply (AC adapter) is bad. It has enough power to light the red LED, but not enough to power the TV.http://shop.ebay.com/?_from=R40&_trksid=m38&_nkw=12+volt+5+amp+power+supply&_sacat=See-All-Categories
