Not sure why chat got closed/ disconnected.
There is big transistor TL010 attached with heat sink near flyback transformer, this is horizontal output transistor, check it and replace if found shorted.
Thanks.

There is a sub-board in this set that powers the convergence circuit. Often a big Ic shorts, two diodes and finally the main fuse. not something you can fix yourself.

My RCA D52W20 turn on with a blue screen and then turns off within 3 sec's. It goes off like someone has switched off the TV. The light blinks and goes off. Can anyone help


Your blue tube has a short. What you are seeing is the TV turning on and the blue tube going to full brightness. It then draws enough current that the television's protect circuits shut it down.

Need the full model number which should include a BYX or just YX followed by a number. Going off the D52W20BYX1 the blue tube would be part number 263049 which https://www.encompassparts.com still has a few for $220 before shipping.

Hello lindseyskirk,

This is a common problem with this TV set as it uses the ITC222 chassis. The problem is usually localized to a group of capacitors
CP120, CP140, and CP150. If you have a background in electronics I can send you the schematics and you can unsolder them and replace them using the schematic to get the values from. If you do not have a background in electronics, I would suggest you have a qualified Television Technician do the replacement for you.

I hope this helps,

Thank you,
