Question about Standard (CRT) Televisions

2 Answers

Broken TV My TV (an RCA 29" CRT) has stopped scanning and there is now a dazzling horizontal band of light across the entire width of the screen. Can it be fixed? In the good old days back in BT (Before Transistors) all that was required was to replace the vertical oscillator tube but I don't know which component to check in a newer set. Thanks, Doug

    Thanks for your help regarding the following i posted yesterday:

    The set is an RCA Model #F27668, The chassis # is CTC203AA and the Serial # is 034621278. Oh yes, and I'm mechanically deprived.



    Thanks,

If you have a tuner like the one in the picture of the PDF file, more likely you will need to resolder all the grounds around the tuner shielding.
Good Luck.

You have a failed vertical output Ic. It will be a 7-9 pin Ic on the board shouldnt be hard to find to replace. If you give all of the info for your tv we can get you the part number

What is Horizontal scan output fault? is HOT is faulty or other problem?


Horizontal scan is the scanning left to right on the screen to make up the width of the picture. The height of the picture works the same. This is not an easy thing to repair. You will have to find someone wit the experience to troubleshoot it.
sorry but hope this explains a little.

Rca 32 inch tv


this is a frame fault
the fact that you can still see the line when the tv is off is because you have been watching with the line and it has burnt into the crt.

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

RCA CRT TV thin white horizontal lines


Look for bad capacitors in the vertical deflection amp, and in the pin amp sections. This is common on most of these types of TV sets.

The caps tend to go high in ESR with age. It is best to use an ESR meter to find the bad caps. It will be a lot faster than workign out waveforms with a scope.

Wikipedia explanation about capacitor ESR:

Tube TV - one thin horizontal line of bright light


Vertical defection failure. Common failure. Pretty easy to repair ($50-75?). However, my general rule of thumb is not to waste any more money on TVs over 10 years old. Too much other stuff in there ready to fail as well.
