Tv comes on and shutts off immediately

I had a tv repaor 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?

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.

I turn on the tv then it turns back off on its own, ill click the power button then the solid blue light comes on, then it just shutts itself off right after.


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Polaroid purple screen


I started to experience this problem as well. Eventually one day I turned my screen on and all the colors were crazy. Purple, Blue Yellow Green. I thought my TV was broken but then I noticed as well that the menu was not displaying the same issue. After messing with the menu for about 30 minutes I found the solution.

Go to SETTINGS. Then go down to DEFAULT. Select default and everything will be fixed.... for now. I think unplugging the TV over and over screwed up the settings. Hope this helps.

Did you change any of the 6.8 ohm 1watt resistors with the ICs? That chassis always blows at least two of the 6.8 ohm resistors often four of the 6.8 ohm. And you cant always tell by looking at the resistors , they have to have one side unsoderd and lifted from circuit. There are 11 of them 3149 - 3160 are the 6.8 ohm resistors that need to be checked.

TV won't turn on immediately


Right now it should not be expensive to repair,the symptoms point to loose solder conection and it has gradually become worst,if you take the set to the shop it should cost less.What happens is the 10 legs the vertical ic has get overheated and loose,to prove this tap on the side of the set just to see if it reacts,it should also be check for other overheated areas while in service.If the quality of the picture is good then is worh repairing.
