Check the swithed mode power supply section. Some sets uses Ics for control the power regulation, while others uses transistors as oscillators and choppers. If the power to the oscillator section of the SMPS is absent, the supply system won't wake up. So many reasons are there. You just check the resistor, usually connected from main DC rectified supply, to energise the oscillator section of the SMPS. In most sets it may be two resistors in serial, usually 270k 1W*2. If any one of this get opened, the power supply will not start up. Check it first and preceed. If the set uses Ic as regulator controller, check the positive supply voltage at the respective pin of the Ic.

I plugged in a computer and changed the input to VGA and the TV went blank


It sounds like your tv is in sleep mode.

What are the settings for the computer? Make sure it is set for the vga output. If it is a laptop, this is usually done with a function (FN) key. On your settings screen you can set the resolution and which monitor you are using.

I have a GE model 52GW945 . It went blank, no sound, no video just dead


Hello,

First thing to check is the cable that is connecting the television to the main power source, then you check the power panel. If it is not faulty, then the problem is that there is a burnt capacitor inside the unit, mainly on the main board of the television.

Run a check on the main board for burnt capacitors and replace them, after doing that, your television should be in good condition once again.

Take care and good luck

I have a GE TV model: 27GT271 and no sound


Possible cause of the problrm is bad/poor solder on the grounds for the tuner circuit shield an the bottom (solder side) of the circuit board. Grounds need a wire jumper from point to point. This was a common problem for those sets and ocassionally it would take out the eeprom chip with it. (Various other problems were shrinking picture/fuzzy picture and intermitt. power)
