Question about RCA TruFlat 27F520T 27" TV
Power goes on and off after it warms up. I have checked for cold solder joint and have not found what is causing the problem.
Models: 24V511T, 24V510T, 27V512T, 27V513T, 27V520T, 27F520T, 27F50T, and 27F634T
TOPIC: Set comes on by itself
Symptom: When the set is first plugged in or after a power interruption the set comes on
Cause: Set was not taken out of factory mode, or has returned to factory mode
Cure: In the service menu go to setting FAC07, then change the value of OPTM2 to “00”
To enter the service mode simultaneously press “Volume Down” on the front panel and “Info” on
the remote control.
Use the original TV remote for the instrument.
Press “7” on the remote to enter factory menu 07. Use the channel down button to scroll down to
OPTM2, then use the volume buttons to set the value to 00. Press the “Sound” button on the
remote to exit the factory mode. DO NOT turn the set off until the screen displays “OK”.

Check vertical output section getting more heat. Due to this section also cause on and off problem. You will not mentioned in sound side. During this condition you get the sound or not. Check the audio supply voltage also.

Tips for a great answer:
This is an indication of out-of-regulation in the power supply section. The very
common caused of this fault is the leaky
electrolytic capacitor in
that section. It will drop the supply from normal voltage and
will disable the unit. Sometimes it has a bulged/dome at the top but not all, it is better
that you have a capacitor
checker/tester to determine
its condition. Also, bad
solder joints can produce the
same symptom, it is hard to spot, you should use table lamp/portable lamp for
finding the cold solder. Once isolated the faulty capacitor and resoldered the bad solder joints your unit will back to normal again
If you don't have necessary tools
and test instruments, and can't do the job yourself, I would advice you to
look for a professional to troubleshoot the problem. Don't
attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored
electricity enough to hurt you with a little mistake only.
Also check if your unit is under warranty /extended warranty,
avail it because the manufacturer of your unit will fix it for free. Don't open
the back panel, this will void the warranty.
Hope I helped you.
Have a nice day!
