Question about GE 32GT740 32" TV

1 Answer

TV turns itself off after a few seconds, no picture at all

When I press the power button, I hear the TV turn on. What I here is like a relay click, no sound or picture from the TV itself. It will shut off after maybe 5 seconds then turn itself on again. It will do this repeatedly, never do get a picture or sound. Also don't get the sound of the CRT powering up, if you know what I mean.

Sounds like the typical Flyback and shorted horizontal output transistor. Problem is the transformer is NO Longer Available

Philips Magnavox 32MT3305 keeps shutting off with relay clicking. The green power light stays on but the picture and sound go out right after the orange status bar goes away. If the channel up or down...


the relay is the safety protective device..sometimes a defective component or something. maybe an overloaded power supply might caused this problem..so before any thing could gets worst..the relay will shut the unit..

TV turns itself off after a few seconds, no picture at all


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

As far as fixing goes, you might as well get a new TV... Unless its a LARGE EXPENSIVE HOLY $%^# TV, It will cost more to fix, than to just buy a new one, unless its under warranty, which being an older model as that (or so im reading) It may not be covered.

Try unplugging the TV, and while unplugged, hold down the power button for a full minute (yes, with the plug NOT in the wall) after a minute, plug it back in, and try. Its a hard reset. If it still does not work, and you've tried different outlets, It's probably a repair issue, and you'll need to get someone to fix it, or just junk it :-/
