Question about RCA 27F530T 27" TV
This is my daughter's set and I have not looked at it.
I assume it may be a power supply failure and was looking for a schematic and parts list to determine if the power supply is a replaceable module or distributed within a larger circuit board.
Replace the cpu of your mainboard and check the out put voltage of your dc power.

Most of the time TV problems arise by power supply noise. This noise in the supply is usually caused by Electrolytic Capacitor failure. If you are technical, you can get the schematic and look for the voltage regulator circuits. Measure the voltages with a DVM using both the DC and AC settings. If the DC setting is lower than normal, you will probably see about .5 to 1v of AC voltage on the line. Look for the large capacitor in the regulator circuit and replace them. Cost about $.50 each. Get new caps with slightly higher voltage rating (if they will physically fit).
