GE 35gt740-powering up and shutting off by itself

The problem manifested itself in one day, happening more and more fequently. The tv will turn on for a few seconds and then shut off. I am semi-skilled with electronics but have no repair manual for this unit. Are there any "shoot for the hip" ideas. From what I have read this happens alot with this tv (chassis number ctc203ca5). I have also read about some cold solder joint but don't know where to look to be able to identify this problem. Any help would be appreciated,thanks.

The first step is look for a small coil, L14401, one side connected to the horizontal output transistor and the other side connected to the small horizontal drive transformer. Resolder both pins of the coil and the 4 pins of the drive transformer. Let me know if that cures the problem.

Do internal speakers need to be off for external speakers to work

I have found in some instances my external speakers need to be off. Mostly if I use my smart TV on Netflix or Amazon Prime. If you have external speakers attached it is better to turn off internal speakers.

Does the GE 35GT740 model have a digital tuner?

As far as I know, this set DOES NOT have the required tuner capability. Please note that the changeover only effects those using rabbit ears or a rooftop antenna. If you have cable or satelite, no change will be seen. The change over is from an analog broadcast signal to a digital one. Your set has a digital tuner that expects an analog input signal.

Hope this helps,
Dan

GE 35GT740 35" NO SOUND

Did you try turning up the volume on the remote or front panel?

Also, try unplugging the TV from the AC outlet for about 15 seconds to make the TV do a re-set.

Beyond this, there is most likely a failure and the set will require service.

35 in. GE tube TV volume issue

The front panel control assembly, or the circuit area for this panel most likely has a fault condition.

I have also seen some of the button switches fail on the control panel.

Pioneer sd532hd5/kuxc/ca powers down on its own

Could be a few things.First check your sleep timer.Sounds like a fail safe mode that when the tvs left on accidentally it shuts itself down so it wont overheat and die prematurely.The last resort is to remove the circuit board and carefully inspect the solder joints near the power supply with a magnifying glass and a bright light.Then resolder those.
