My tv comes on, the power light comes on, but it won't stay on, it goes off by itself a few seconds later. Is there a solution to this?
Panasonic TV TX-25mk1 (UK standard) will not stay on when channel selected, goes back to standby after a few seconds. Eventually stays on after a few tries, and is then normal until next switch-on.
I have an RCA T.V. that the green light comes on then the t.v. goes off by it's self please help fix this problem is it the cable box or is the T.V.??

Re: Tv won't stay on
This is a common problem with the ITC222 chassis, I would check CP120, CP140, CP150 to see if they are bad I suspect CP150 is the one that is bad. Its value is 2200uf 16VDC. It is located on the same board as the IHVT and is in between the Heat sink in the middle of the board.

After further inspection, I believe that you have a blown convergence IC. Most posts point for two IC's. I only have one. STK393-110. There are 12 - 3.9ohm 2w resistors around it . I think they may be bad as well. The 2 Pico fuses feeding that circuit (+24/-24) may be open also. So, with that said...... Think we have the problem cornered?
All symptoms in your TV shows that you need to replace its Lamp as it has been consumed its life hours and TV requires new lamp. Lamp can be obtained from Sony Website. Price is $200, Hope this info will help you to enjoy your Sony TV in coming days.
i have seen this before and it may be the front power button being stuck and when your remote turns it on the stuck button turns it back off again. I have an older mitsubishi that will not boot up right sometimes and i have to unplug it and plug it back in fot it to come on. I used to pick up broken tv and fix the power buton and resell them
