There must be a shorted power transistor in the power supply area. Check the voltage output of the transistor to determine which part is having a short circuit.

Convergance is off


I have an RCA 52” HDTV Model R52WM24 the other day it developed a convergence problem (The picture took on a 3D effect and it the screen had an hour glass type of shape)

This appears to be a common problem or a pattern failure.
I wanted to confirm that I did find the fuse p/n FL231 to be blown.
I think it said the RCA part # is 259213 and it is a 400 ma, 125V fuse, Looks like a square capacitor by the fly back xfmr.

I bought a generic part from Digi Key and it seems to be the identical replacement part to the fuse that was in the circuit.

The Digi-Key part is part # WK4440BK-ND (99 CENTS EACH).
THIS IS A 125V, 400 MA ( 0.4 A FUSE). Digi Key PHONE # IS 1-800-344-4539

I am watching the TV right now for last 3 hours and it seems to be a good fix.
The fly back transformer solder connections looked good but it is recommended to re solder these part ( so I did).

Good luck

Can't find 2A 125v fuse replacement for on-off will 250v be OK?


There is no difference between a 125v and 250v fuse. The most important thing is the 2Amp. This fuse is probably the line fuse and could be the only trouble and may have blow with a line surge. Make sure the 2A you use is a Fast Blow Type. If it does blow again you most likely have a internal power supply failure.

Panasonic ct-32sl13g blowing fuse by power supply


You will need to remove the back of the TV. Don't worry, it's not that bad.

There are 4 screws across the top, one on each side, one right next to where the power cord goes into the back of the case, and the two more by all of the video connections **These are the most important to remove because they attach the main board to the back of the case.

Once you have remove the screws then the entire back of the set will slide off. If you look where the power cord attaches to the board you will see a small fuse. This is a 6.3 Amp 125 volt fuse. You can replace it with a 6.3 Amp 250 volt fuse from your local Radio Shack. A four pack costs between $3 and $5.

Make sure that you check that it works before putting it all back together. Check for any loose connection cables while you're back there. I found a few when I did this.

Good luck!
