RCA P46920 TV will not turn on, it makes a beeping noise.


Shorted horizontial output transistor q14401 -I think- and bad flyback transformer(high voltage transformer).The noise is the power supply starting and shutting down very quickly because of the shorted transistor.Very common problem,but some of the flybacks are no longer available from RCA.Sometimes you can use generic but questionable life on some of these.

Problems with RCA 27R410T 27


The flyback will be unmistakeable once (IF) you have the replacement and the HOT will be mounted on a heatsink very close to the flyback, sometimes on an apparent shield surrounding it.

Don't fail to buy some silicone grease or a silicone rubber pad for the transistor; these things are pretty close to death when everything is normal and will fail if you sneeze.

The RCA PN may be hard to find, messages I saw implied that but NTE has a substitute number for the S2055N:

http://www.nteinc.com/specs/2600to2699/pdf/nte2636.pdf

This part should be available at most electronic suppliers and has an isolated housing making an insulator unnecessary but not some thermal help.

But the flyback . . .
That could be tough; my former supplier, who always had what I needed is gone and the market for replacement flybacks is shrinking daily due to the death of CRT monitors and TVs.

RCA P46921. Just changed flyback.


if nothing has been tampered with ie. focus controls, lens focus, I would check to make sure the high voltage lead is seated correctly.

RCA P46921. Just changed flyback.


First, this assumes nothing else is going on to cause it. Here's what I did. Go to the 'green grid' via the v76 menu and go through the alignment there. Notice that there are red letters, blue letters, and a green grid. While you are in this screen, adjust the red, green, and blue focus watching the individual color's item until they are in focus. If they won't focus here, they won't focus and you have something else wrong (what I do not know). Then, return to normal programming, then select menu on the remote, then screen, then adjust projection tv convergence both horizontal and vertical crosshare. That ought to get it.

Big mistake


what was the origonal symptom before replacing the flyback? You could try using epoxy on the wire get a nice size glob of it on there where the wire got cut.
