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?
I have a RCA TV Model #20F424T. It is brand new. Upon turning on the TV, the power light will come on, and if I do nothing, shuts off within 5 seconds. If I press input to change which a/v's the TV uses, a thin blue bar through the center of the screen appears, changing in length depending on which input the TV is set at. On the DVD input, I can hear audio just fine, but there is no picture, just a short thin bar in the middle of the screen. Again, if I do nothing, the TV shuts off on it's own within 5 seconds, even with the audio coming through just fine. Ironically, the "Find your product:" bar is not recognizing my model number, but I've triple checked it: 20F424T. Therefore I have selected the closest in appearance.

Before going OFF, the standby LED might blink. These blinks are fault indication. The number of blink should be counted. Count the number of blinks at one time, before the TV goes OFF. [eg: 4 blinks Power SOS P Board; 6 blinks Driver SOS 1 SU / SD / SC Boards
(SC energy recovery circuit)] and so on. you can get more details from this site named 'Electro-help'. You can reach it by searching the keyword "electronicshelponline" by internet.
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?
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
The TV is in some kind of protection mode, the blinking LED show you an error code.
Try pressing 062596 and then press menu button (do these in quick
motion, don't let them to time out while keying)...see what happens
I also heard that this problem appeared with some people because the of
the burnt fuse in the TV. To fix that it has to be taken to the tech
And yes I also heard about this issue many times, seems like this TV set is very popular with this kind of problem.
