RCA G35831AT


This is a loss of the "pincushion correction" circuit. These sets are known for bad high voltage capacitors in the horizontal circuit that cause a loss of pincushion correction. It could also be loose solder connections in the horizontal circuit. This can be a dangerous circuit to work with. Have a shop check it for you. Thanks for using fixya.

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,
Dan

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?

Thanks,
Dan

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.

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.

Sound but no picture


yes the tv is fixable an estimated cost is about $40.00 to a $200.00.the problem is in the video circuit.
