Question about RCA R52WM24 52" HDTV Projection Television

1 Answer

Could I possibly have a bad flyback transformer

I had convergence problem the tv would stay powered but the screen had a bow in it. I replaced the FL 231 fuse link, it worked fine for three days. Now the T.V. has a different problem it shuts off and turns back on by its self. I unplugg it for several minutes the tv comes on and stays on with a good picture after 5 min. then the problem comes back.
If this is the transformer how do you disconnect the to red lead wires from the transformer...

    Hey Thanks, Yes found when they soldered these boards they used lead free solder, so I desoldered the flyback transformer and then resolder. Also found that the problem with the Fl 231 blowing. Apparently DL 231 I believe it is a diode located just right of the the 3 red fusible links when it goes bad its takes out FL231 fusible link. The TV stays on and has a good picture, but sitll have 3 color lines at top of the screen. Could there be another component, I heard something about the cv's that are located behind a heat sink, Do have other solutions would appreciate any thing you have.

I would try resoldering the flyback connections on the Circuit board. if the flyback was defective it would operate and you usually get 3 blinks on the LED indicator. Sounds more like a solder issue.

Bad convergence. Possible bad convergence board(s), or bad connections at flyback on power board along with a little brown/orange fuse by the flyback.

I have an RCA HD52W59 HDTV and my kids were watching the other day and all of a sudden the screen went bad. The sound is ok and you can still see the picture however it looks like your watching in 3D...


This is normally an easy fix. I've fixed several of these. When you get the back off of the set, there are 3 small square brown fuses located at the back left corner of the set, if looking at it from the back. They are located next to the right side of the flyback transformer( the large gray or black thing sticking up with the thick red wire coming out of the top). One of those fuses will be open and needs to be replaced, and the pins on the flyback transformer need to be resoldered on the bottom of the board. They will come loose and make the fuse blow. This will fix the problem 95% of the time on this set.

Philips 55p9161 shrinking into the center of the screen


Generally if the HOT is "going" then it's gone. When they go they short and take out the B+ fuse causing a no power condition. Could be bad solder connection in the convergence circuit or possibly something else loading down the scan derived power supply. Could even be an intermittently shorting flyback transformer (the high voltage transformer) which shuts the set down for a split second but not long enough to kill it completely.
If it is the flyback, chances are it will eventually go all together and it will take out the HOT when it does.

The convergance menue is gone. I need to adjust the convergance badly but it is no longer in the menu


You need to resolder the flyback transformer and replace fuse FL221 off pin 11 of the flyback transformer. The convergence power supply is not coming on so system control thinks a convergence circuit is not installed.

I have a RCA HD 52in and I'm have a problem with the Convergence Ic's


Hi, rca`s don`t have convergence IC`s, they use an entirely different system to perform convergence, you have a blown chemical fuse and 3-6 bad solder joints on your flyback transformer. replace fl231 chemical fuse rated at 400ma. right beside flyback (theres 3 of them your bad one is the middle one)and while your soldering re-solder all of the flyback transformer pins and your tv will be back to normal :) video-tek

Rca hd52w59 3d screen colors are seroperated no convergence


i have found the reason for the fl231 fuse blowing is faulty solder connections on the flyback transformer is the main cause. I have came across only one bad signal board that cause this but this was very very rare 1 in 1000. This is a very specific fuse, .400 and it is recomended only to replace with exacte one. consult the fl231 problem in the tips and tricks section.

Rca hd52w59 convergence?


Before you go and buy parts it might be worth your time to check the convergence power supply fuse. It's located in the back of the TV just to the right of a large black component with 2 red wires coming off of the top. This is the flyback transformer. Just to the right of the flyback you should see three fuseable links that look like chicklet's gum. The one that may have fried is the one in the middle, it's a 400mA 125V fuseable link. Hopefully thats all your problem is.

RCA R52WM24 52 in. HDTV won't stay powered on


sounds like you have more problems than just the fuse.. did you resolder the connection when you replaced the fuse. this is what causes that to happen.. fuses blown for a reason. ussally something is shorted. that particular fuse blows because it is a very small fuse and doesent take spikes in power to well. so when a intermittant connection begins to cause ossillations it shakes that poor fuse. it however sounds like you have more than that. does the led on the front flash when it shuts down.
