Question about GE 35GT740 35" TV

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.

When i turn my tv on it comes on for a few seconds, makes an odd speaker noise then shuts itself off.


What is happening is that there is an error happening within the TV that the TV knows is wrong when it conducts a self check. so it is shutting itself off to prevent damage. contact its manufacturer. or if you think you may be able to repair it yourself, here is a service manual link. www.audiolabga.com/pdf/FLM3232.pdf

Sometimes when the TV recives a brodcast signal for a new update to the mainframes firmware, it will have to turn itself on to install/recive the update and aslong as it is connected to a power source it can do this. hope this helped answer your question. Have a good day :)

Upper left part of screen turns blue after about 30 minutes


You have two possible causes. First the Main bd is going bad and second but most probably the Panel is bad and needs to be replaced.

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.
