I had a tv repair guy come buy and look at my set and I told him what was happening. My blue was out of wack and like every other day the tv comes on and shutts right back off. Today he took out the STK392-120 ic's. So then he still tries to turn the set on. Will they work without the ic's? If so what wrong with my tv?
I pulled the yolks and the tv still wont give a picture , the only time you see a picture is when it is turned off or stand by for a split second i also have no sound and no video from the dvd payer , befor replacing the converg i had picture and audio and i also had sound from the dvd but no picture can you please help .
Cheers

He was checking to see if the set stayed on with the ICs out if it did the ICs are shorted. Its easier to unplug the convergence yokes and try it but some techs do it differently
SOURCE: Tv comes on and shutts off immediately
Well no, it won't exactly work with out the ICS which is an internal control relay card. He most likely was thinking it was a power distribution problem. My suggestion is to look at the power supply and make sure nothing is bridging any of the circuitry. Just like a computer the on and off button is attached to a set of pins, and just like computer motherboards the controls also exist for a reset. And if anything bridges these pins turning on the unit will just cause it to shut down again. Also look for water damage and heating damage that might have caused problems with the power supply unit.
