Question about GE 31GT740 31" TV

1 Answer

I have a GE 31GT740 31" TV That turns itself off and then back on every few seconds. There is now a broken (dashed) white line that goes from the very top center of the screen to the right side. The TV will stay on until a comercial comes on and then begin shutting off and back on several times. On cable channels that have no comercials, it will stay on for an entire movie and then begin again when the comercials start. When playing a DVD it will cut on and off at the beginning, when previews, etc. are playing sometimes say "unusable signal" then play the DVD fine. Any suggestions?

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!

Is Worth Fixing Panasonic PT-50LC13-K Rear Projector TV


most likely a bad mainboard or bad caps in the power supply. Borderline on the repair-ability. I would check Shopjimmy.com to see if used parts are available. If they are it may be worth it.

How do I Fix LCD White Screen?


If you see "fractured lines" across the screen, it would appear that your LCD screen is broken. That's the only way these kinds of lines appear.
You need to replace the screen.

TV TURNS ON,LINES ACROSS SCREEN THEN TURNS OFF BY ITSELF


sounds like a vertical problem, usually you'll see one white line across the screen, but one I worked on would come on and the bottom half of the picture was gone and there were lines across the top of the screen.

If you know how to solder & can find the vertical output chip then you could try resoldering the pins. If this doesn't fix it then it needs new parts.

GE 31GT740 clicks off and on


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

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock. Be careful !!! Stargazer
