Question about GE 31GT740 31" TV

1 Answer

GE 31GT740 clicks off and on

My 5-year-old GE 31GT740 turns on ok. Within a few seconds, it turns off by itself with a clicking noise, and a few seconds later, clicks on again. After a few cycles of "off" and "on", it stays off. It acts the same way whether I use the remote or manually turn it "on". Is it worth fixing? Any help is appreciated. Thanks, George

    My 5-year old31GT740 turned itself off earlier this week and now only clicks a few times when you puch the on button.

    Mine is also five years old. It used to turn off by itself and stay off. Now it clicks like it is coming on then keeps making a clicking noise for about five seconds then stops. It does not turn on though. Before it stopped working completely, channels 2-6 would only have static. Repair shop says transformer and some transmitters are out and it will cost $169 to fix but I don't trust them anyway.

    Have the same clicking problem, sounds like tv wants to turn on but nothing comes on?

  • dkinsman May 27, 2008

    I have a very simular problem I can turn on and off the tv with my remote after hitting the on/off botton five or six times. It clicks like it is coming on then about a sec. it clicks again like it is turned off. Where my problem is different is that when I do get it to turn on my remote will let me change the channel on my cable box, but if i try to change channels on the tv itself the guide comes up. This happens no matter what bottons I press. I can't even adjust the volume. The bottons on the tv don't even work. Can't use them for anything, not even to turn the tv on or off, adjust the volume or change channels.

    The TV will turn on and off by itself. Also the channels will change constantly on it's own. I have unplugged the circuit board which controls the buttons on the front of the TV and the problem stopped. Only problem now is the remote does not work and of course I can not operate the TV. The part I am looking for is 1515631E.

Dead, led flashing red/green at first, then going to red standby
Replace C604 (1000uF, 16v) elec. cap. It is in the decoupling circuit for the 5 volt supply
Reverts to standby from switch on via TV or Video
No 5v rail because FET MTP3055 o/c. (BUZ71 will do nicely)
Goes straight to standby, after a quick burst of power
Replaced R952 (39K), had gone slightly high

I own a GE 31gt740 and I heard a squealing noise a few times, but TV still worked. Then, I turned it on one day, heard the squealing noise, then saw a little smoke, some crackling, and no sound or picture....

I think that the problem of your tv is the flyback transformer. The noise you are hearing is the high voltage, it is leaking from the flyback transformer. The smoke you see may came from the flyback or the capacitor. To be sure to the problem, try to remove the back cover of your tv but be sure to unplug it. Try to plug it, then turn on your tv but you should turn of the light so you could see the high voltage that is leaking but be very careful when doing it.

I would be concerned with the vertical IC. This IC has pins that have separated from the board itself. You will note the area under the vertical IC is almost black. It will do no good to resolder this. You will need to replace the vertical IC with a new one. And be sure to replace those electrolytic capacitors near and next to the vertical IC. Bad grounds on the this IC will cause your TV to shut down. Also inspect the rest of the TV board. In some cases the retrace cap will always need resoldered! But please inspect all areas of this board for bad grounds and resolder as necessary! Good solid grounds will give you a dependable set. Thanks for asking and show a few hands of support!

Samsung LCD HD TV Model # LN-S4041D > 4 years old - working fine until today - While watching TV, I heard 2 loud beeps and the TV image was lost - initially frozen pixels and some moments later .......

Th clicking is from the power relay. You will have to open it up, the first place to look will be the power supply module, look to see if it has any bad caps with leaking/bulging tops first, caps can look OK but can be bad due to high ESR.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

If you have a 5 year warranty, you should not take anything apart and consult the place where you got the appliance.
They should be able to tell you exactly what is covered under warranty before they work on it.

The GE (actually RCA) 31GT740 uses the CTC203 series chassis. The first thing I would do is resolder the coil on the base of the horizontal output transistor and the pins of the horizontal drive transformer, as well as any other solder joints on the main PC board that look weak or cracked. 9 times out of 10 that cures the symptoms you described. If you do not have experience soldering parts on PC boards then have a qualified tech handle it for you.
