Re: my RCA F32650 turns on and has sound but no picture
You will have to take this in for service. The possibilities for your symptom are numerous - it could be flyback if the audio voltage is derived from the wall ac; it could be CRT; it could be video blanking (to protect the TV).
A technician need to check voltages to provide a suggested repair.

Picture tube failure is very rare. It sounds that the horizontal output transformer, that supplies voltages to picture tube to work are not present. A damaged horizontal output transformer might be the fault. Contact any experienced service technician. This is a repairable fault.
Look for bad solder connections on the solder side of the board: You have to take board out of the plastic and slides out. Look around the high voltage transformer pin connections and large transistor associated with it and all connections associated with it too. Use magnifying glass. Could be hard to see. You could also shotgun the whole section by just soldering all associated connections. Look for burned connections also.
Heres the fix for your set, replace the following 2 parts:
1) flyback transformer RCA part number 257805
2) horizontal output transistor RCA part number 237470
you must be proficient at soldering & un-soldering or you can`t replace these yourself, be advised that the anode lead coming from the top of the flyback transformer can carry a VERY NASTY shock if not discharged properly before trying to remove it from the picture tube, I`d strongly advise you to call a tech unless your familiar with this type of repair, BMW Rider
