Question about RCA 20F514TD 20" TV

1 Answer

20FS514TO Tv will not turn on after being off for awhile. As soon as the screen lights up it turns itself off. It stays on after a few dozen re starts. The Chinese junk is about 2 years old. Have any ideas? Jim

    Hello, I am an avionics tech and know how to replace components. What I want for that tv's power problem is the "test Points" and the voltages that I should be seeing at each one so as to determine the exact problem. I do not believe in changing components till the problem is resolved. It you can't supply me with the requested info, please refund my money.

    Sincerely,

    Jim

The power source has aged prematurely and it needs several attempts to delivers the necessary starting current - you will have to open it and replace the filtering capacitors and check the regulating circuits and the board for heat damage (their aluminium radiators are undersized).

My Sharp LE820 Aquos LED TV recently auto turn itself off, when I turn it back on, a few good 10 minutes or so later it automatic turn itself off again.


Please check that the sleep timer did not somehow get set. If it's not the sleep timer, check if the panel stays ON longer after it's been off for awhile to cool down. Possibly a heat problem with the power supply or main board.

Tv will work for awhile then the screen go's out if I turn it off for awhile it will work again


Hello Foley Hi, I need a few question to ask,
  1. As the TV goes out, Is the audio present? If yes, then the problem would be a soon to fail inverter board. In no, then both the sound and picture are out, this could be a power supply failure.
  2. Does the power light also goes out? turns red? this is a power supply board failure. A replacement board is needed to repair this type of trouble.
In number 2, the power supply board might have loose or cold solder joints, when gets hot, temporarily opens the cold solder, then connects itself again when the TV cools down, If this is the case then you need a technician to find the loose joint. As for number 1, the inverter board needs replacement, you also need a technician to do the replacement.

I have a Phillips big screen tv and the front light is flashing red at all times and the picture will not come on the screen. This light is usually green when the set is on. What can I do to get it green...


I have the SAME issue and so far it seems to be an issue with the fan not kicking on.... I turn it on in the morning, as soon as you hear sound the red lights kick on and I shut it off... it takes a few seconds to shut down so stay close to your remote durring this process and as soon as the "red light" kicks in, turn it off, as soon as it's off, turn it back on... I have to go thru this about 30 times now before I can get the picture to stay on, but it eventually kicks in. Hope this helps!

TV TURNS ON,LINES ACROSS SCREEN THEN TURNS OFF BY ITSELF


sounds like a vertical problem, usually you'll see one white line across the screen, but one I worked on would come on and the bottom half of the picture was gone and there were lines across the top of the screen.

If you know how to solder & can find the vertical output chip then you could try resoldering the pins. If this doesn't fix it then it needs new parts.

Plasma TV keeps turning off and blinks 5 times


Bad capacitors on the power board. If they look swollen or enlarged then they are most likely not holding enough charge.
