Hi there

This is what the power supply should look like if you were to take it out of the television:

50" philips won't power on. get the 4x red blink led light


i have fixed 3 of this tv, with that exact problem in the last 2 weeks, needs a power supply, you can try to unplug it again, plug it in, hit the power button, as soon as it turns green, unplug it again, after 15 seconds , plug it back in, if power doesnt turn on by itself, turn it on, if it turns red again, emediatily hit power again, may have to hit power a few times in a row, but most of the time you can get it to come on this way, once it is on, it should run ok, until you turn it back off, but not a fix, needs power board

AKAI 32" LCD HDTV WILL NOT TURN ON


The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com

Insignia 42 inch TV won't turn on


The power supply is in the protect mode. There are many things in the set that can cuase this. Most likely there is a short on one of the circuit boards, or the power supply itself has failed.

You will have to have the set serviced in order to get it going again.
