Problem with my RCA F32632SB

A few months back this TV's picture was starting to stretch horizontally on the screen to where it was impossible to watch it. One day I got the bright idea to pop the back of the TV off and see if I could locate the problem. I'm not a TV tech so I don't know what it was called, but there was a loose plug on what appeared to be the main board. If I pushed down on it gently, the picture went back to normal. So I left the back of the TV off for a week and when it would give me grief I would reach back there and push on that plug and the problem would correct itself. I know this was dumb, but I work a lot and was waiting for a day off to have enough time to operate on the thing properly. It appeared that a plug came lose and just needed tightened. One day I came home from work and the TV wouldn't turn on anymore at all. Now there's nothing but a high pitch noise coming from it and no power. My best guess is I've done gone and blown a fuse somewhere in this mess of wires. Any ideas?

Re: Problem with my RCA F32632SB

That is a linearity coil not a diode. The coild can be replaced on its own and possibly the board patched up as long as you know where the burned traces go to. The only other way to get the board fixed since RCA never sold main board is go to and contact them on rebuilding the board. You wil have to ship it to them and once they are done they will ship it back. It probably isn't worh the cost though.

I need to find the pincushion circuit on my RCA F32632SB TV to check a problem with the TV displaying an hour glass picture. Where can I find a picture of this or a manual to guide me to the circuit?

The pincushion it intimately related to the horizontal circuits,the electron beam must travel farther to reach the corners of the crt and it does to the middle and so without pincushion circuits the raster would be bowed in on the sides on crts 27 inches are larger.Pincushion corrections straightens the raster by modulating the horizontal yoke current at a vertical rate.In an RCA tv the pincushion circuits are usually numbered 4800and the pin amp will probably be numbered 4801,its drive transistor should be Q4802,R4802 will be the width control,and R4805 the e/w pin amplitude. its inputs from the vertical should be Q4801 (subtractor) Q4803 (buffer) you should have a parabola waveform at 4801,yoke current can be modulated here without effecting high voltage.when Q4802 conducts voltage should decrease across Q4801 and the voltage drop across the yoke increases. The east west pin amp control 4805 controls how much of the vertical parabola is input to U4801 to compensate for changes in width caused by variations in beam current.By varying the e/w control resistor you can know if the circuit fault is in the input or output,if the picture varies in size the fault is in the input to U4801,if it does not vary check the output or U4801......hope that helps

Hour Glass picture on a RCA TV F32632SB

I looked up this model and found the following electolytic capacitors to be the most likely culprits within the pincushion circuit. Check these first. The starred one is the one I have replaced in the past to resolve this.

C4851 10ufd 50V
C4853 10ufd 63V
C4854 2.2ufd 100V
C4855 2.2ufd 50V
* C4862 100ufd 25V

Good luck,

Have you ever had this problem?

Sorry Ginko, but a convergence problem would have the curves down from the top and up from the bottom. The hourglass shape is a pincushion problem. This can be as simple as a bad capacitor in the pincushion circuit.

Could you please confirm the model number so I can look up the probable part?

RCA TV with an hour glass shaped picture

I am sorry that its took so long for me to reply been backed up in shop, anyway what you have is bad solder joints on large Diodes Resolder ends on all of them and this should slove your problem if you havent done so by now.

Hello neall,

It sounds like you may have a power supply problem- (HV Power supply). I must ask if you have sound or not? If you have sound it is the HV supply only if you do not have sound the Low Volt power supply and possibly the HV power supply/Horizontal section has a problem. I would suggest that you take the TV to a qualified TV repair shop.

I hope this helps,

Thank You,

Picture, No Sound

Try unplugging the tv for a few seconds, this will reset it. Also check the menu and make sure the speakers are on.

Intermittently picture will lose horizontal size, now even the RT4201K fell of and no Degausing

make checks on the yoke, flyback,and the HOT they could be your source of problem.also check the horizontal circuit.good luck.
