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.

Re: TV turns itself off after a few seconds, no picture...

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

Flashing Standby/Stero light and No picture.

How good is your picture when it did come ? Is it as good as it once was ? Or is it alittle washed out. If it is washed out the picture tube is weak . Sometimes turning up the screen control alittle would solve problem but if you turn it up too much you would have faint white line running diagonally. Now if you think the picture was good before you this problem video circuit would be your suspect . Jungle IC or something in the RGB circuits . Good luck

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

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 :-/

So far you have done all you can and you have done everything right. The fact that the TV turned off by itself and then turned back on by itself suggests that one or more solder joints have come loose inside the set. A qualified tech should find this easy to fix, and Sony sets are always worth repairing, so it is now time to have the set serviced by a tech experienced in Sony standard sets.

Picture tube doesn't turn off

The power relay driver or the relay itself is bad. Its sticking closed so the voltage is there for the power supply but the micro has turned off the tuner.
