TV Wont come on

I'd add something to this. We had the same issue with a 40" coby. We'd declared it dead and after a few days turned it on again to show the problem before trashing it. The TV came on. We've since learned that there seems to be a HDMI handshake issue related to this tv. If you turn it off with HDMI devices still sending a signal, it will periodically return to this point, and take a day before it will turn back on (I guess until the caps are fully drained.) If you turn the TV off first and then devices however, this never seems to happen. Dunno if this is the same for others, but I'm curious

I understand in a way but if it is brand new--take it back and either have it exchanged or sent in for repair. From the brand you are in the UK? Many companies will insist it goes for repair (a shell game) but most major stores selling sets have an unwritten rule: for first 30 days it can be returned and either exchanged or credit given to purchase another set--reason does not matter= you do not like the color of the cabinet take back and they will (not be happy) do something.

Seen a few here in USA where set when removed from box was destroyed in shipping--told customer to take it for repair---again a shell game by maker to have seller deal with this issue.

Don't take no for an answer would be my solution here.

it has a built in safety. there's a problem with tv board

Our Insignia will not turn on. It was on and then suddenly went black. We checked the power to the plug in no problem there. We unplugged it and let it set for a few minutes but it still will not come back on. We have had some low voltage a couple of times today. It was plugged into a surge protector.

Common problem with the older projection Magnavox TV set. The opto IC chip has failed. Try www.magnavoxhelp.com - They have instructions and kits on their site.
