RCA R52WH74 turns off 3 times

Hello Kira-chan,

You are going to have to take those capacitors out of the Tv and check them on a capacitance tester. Some digital multi-meters have them, but I would suggest using the LC102 by Sencore That way you can check the ESR, and the dielectric absorption of the capacitor. It is my suspicion that these caps are bad, but should be checked before replacing them.

In addition check the BLUE and RED CRTs for cracks around the neck oy the tube, BE CAREFUL.

I hope this helps,

Thank you,

good day sir, your problem may be overheating, check the switching regulator, it my be the IC or the transistor, if possible place thermal silicon grease between the heatsink of the regulator, make sure its screwed tight. hope this helps. thanks
