RCA pix tearing horizontal lines

Starting problem Dead TV. RCA 32F530T, chassis ATC113CD4. I Replace flyback # 257807 along with the H-O/P XSTR (2SC5148).
> Problem fix. Everything work fine, except i have hatching or tearing lines at one or two places on the screen depending on the white level (contrast), always in half screen area on the top. Same symptom with video and RF input.
>I replace the flyback 3 times with different part # (not original RCA flyback) and suppliers, 257807, 257805 and ACME-2632 (replacement for RCA #261163). Still have exactly the same problem with 2 tv set. I checked parts in the horizontal and vertical circuit, DC supply, everything looks good.
See pictures.
Any suggestion? Bulletin note?
Someone saw that before?

Re: RCA pix tearing horizontal lines

Get an ESR meter and check all the electrolytic capacitors in the set! I am sure you will find many decoupler and coupling capacitors that are on the edge or too high in ESR.

We replaced the transformer for our RCA F27650. It was sparking and now it is not, but now the screen won't turn on. It is just black. We hookd all the wires up like they were. we can hear sound, but...

Along with the flyback transofrmer, its horizontal output transistor also must be replaced. I don't know whether you have replaced it or not. If not, replace it too. It can be located very near to the flyback transformer, a three terminal component, black in colour, usually screwed to a metal heatsink. Then switch on the TV and measure the video output voltage at the video output card pluged directly to the picture tube neck. The collector of the video aoutput transistors must come around 145VDC. If it also is there, advance the screen control on the flyback transformer to get a raster. If that voltage is not there, it means that the flyback transformer is not working, and horizontal oscillator stage should be checked for oscillation, check the lined drive transformer for its primary winding open, Check the entire horizontal oscillator section. The collector point of the line drive transistor, the transistor that drives the line drive transformer, a small transformer soldered diretly to the printed circuit board; should be checked with frequency meter. The frequency at that point should come around 15525HZ approx: OK.

I need a transformer

It is not clear from your post, that which transformer part number you wants to know. Anyway I'm hereby send you the part numbers of it two main transformers.
[1] Horizontal Ouput Transformer, or Line Output Transformer or Flyback transformer [HOT or LOT or FBT]; Part number is (257807)
[2] Switeched Mode Power Supply transofrmer [ SMPS transformer]: Part number is (257807)

RCA 32f530t 32 inch tv

This has happened to me quite frequently. I have replaced the fuse at least 8 times. You just take off the back of the t.v. and on the bottom you will see a small glass fuse. just pop it out and go to radio shack and get a pack of replacements. about 4 for 3 dollars.

Buzz When I plug the tv in I get a buzzing sound and the power button does not light up and there is no picture or sound.Could it be a tube?

I will guess you remember tube sets from our parents days !
They stopped being Mfr'd in 1972 !
Best solution for your set = replace horiz transformer and
transistor with RCA part # 's 257807 & 237470................T.

Switch mode power supply not switching and buzzing when powered up.

Common failure " buzzing " cause = bad flyback transformer
& horiz output transistor = replace both at same time.......
part # 's 257807 & 237470 RCA only No sub's.........T.

RCA F27669 27"

The F27669 uses the CTC203 series chassis. The most common cause of that symptom is a shorted horizontal output transistor, caused by a cracked solder joint on a small coil connected to that transistor's base. When this happens, the main B+ supply is shorted to ground so the power supply squeels. Every once in a while I also see the horizontal output transistor shorted due to a shorted flyback (high voltage) transformer. A good tech will replace the horizontal output transistor, resolder the coil and drive transformer, test the flyback (replacing it if necessary) and your set will be back to perfect.

Won't work

It sounds like something in the high voltage (flyback) circuit failed. If any little thing shorts in these RCA's they will not start up. Stargazer

TV won't turn on

I received this solution:
"This was apparently caused by using replacement flybacks. Add a .001uf cap (102k@2kv) from RL03 (the side away from the FBT) to ground. This will shift the picture a little then compensate a little with parameter 15."

In my case, i used an other flyback the HR8934 from Diemen to get a more stable picture without blooming, and add a 440pF (two 220pF capacitor in parallel) instead of .001uf to eliminate the tearing lines.bfde541.jpgac61dec.jpgdda8fac.jpg.
