HD52W19 TV You can hear the TV powering on and the green light comes on but no picture and then it cuts right off after a few seconds it does this about two or three times and then does nothing.

Most likely the power supply board needs to be replaced. It could also be the T-con board or less likely the display itself.

If you don't know what you're doing, DON'T OPEN THE TV UP TO FIX IT, THERE ARE HAZARDOUS VOLTAGES ON THE POWER SUPPLY BOARD, EVEN WEEKS AFTER THE TV IS UNPLUGGED!

If you don't know how to do it yourself, find some local Electronic repair shops, get quotes, try to find reviews on the shops.

I'm having the same problem right now. I get the green light for about 5 seconds (not Blinking) then the light goes out. No sound or picture.

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?

what kind of tv is it, plasma, projection, lcd??

lg tv 26lc7d, when I plug the power cord in the red power light cuts on then turn right back off, the tv will not stay on.

on off sensor sounds like its bad

unplug tv overnight. if that doesnt work the powersupply is probably bad.

my tv will not come on

Look at this link on the bottom to see what the blinks tell you.
