Picture tube will not come on.... rca mod f35731 mb chassis ctc169j56 ser 707261399h green light comes on but no picture.... help fuse?> bad picture tube...?


Bad grounds on the power supply are common on these TVs. The power supply will have the flyback transformer. Resolder the flyback, horizontal driver transformer, power resistors etc. Check and study the vertical IC and see if the pins will need resoldering as well. Inspect the small board that is connected to the CRT, and solder this, as necessary. This is a good start for repair, thanks for asking and show all hands of support!

TV does not turn on model RCA D61W20B


first check all fuses they are small, square ,RED and can be confused with the square small caps. the sizzling is prob. the flyback transformer (what the h.v. wires from each tube plugs into) if you are only getting green then tv shuts down or is dead now. i would replace any bad fuses and replace the flyback transformer. also make sure you do a very good visual inspection of all the boards.

Flyback transformer and horizontal output transistor change out


There is a little loose sleeve at the transformer. It can be pulled out, but it is best to squeeze the sides through hole on each side of the terminal to remove the sleeve. The wire just comes out with a small pull afetr the sleeve is removed. Good luck.

36" RCA- loud whine/squeal when it is plugged in, otherwise no power.


The HOT Hortz output transistor has gone home, 99% of the time from a faulty IVHT (Flyback Transformer), very common on the ctc187cl* chassis. The factory Flyback is no longer available, I have had problems finding an aftermarket one to replace it with.

The HOT is a BUH517, but you can also use a 2SD5129. It is the transistor mounted on the siler heat sink with a metal clip rather than a screw, just in front of the flyback.....

If you replace just the HOT, most of the time you will get a rapid arc (27,000volts - BE CAREFUL!!!) from the lower (yoke) post on the flyback. If the flyback is shorted, It may also just burn out the HOT and go right back to "squealing"....

Good luck finding the flyback!!!

Flyback Transformer


Flyback transformers rank about a 5 or 6 on dificult to repace.. depending on the model of tv that you are working with.. the rca itc222 can be difficult.. dependend on your soldering experences. To replace this one you have to pull the chassis tray up and out to get to the bottom... unsolder the pins ussally a vacum desoldering tool is required because it is important to remove all solder from the pins..then gently pry the clips that hold it on the board... this is where you can mess up unless the pins have be completly solder free you can crack the board... NOW the hard part... removing the wire from the flyback.. if the flyback is the type that the wire comes out. the wires will eather have a clip around the large wire or you will have to go to the other end of wire and pull it out from the splitter. eather way this wire is firmly in an will require gently but extremmly firm pulling to get out.

Tv will not turn on with remote or when I press the power button on the tv.


The P52960 uses the PTK195 series chassis. The most common cause of that set not starting up is a shorted flyback transformer. It is quite easy to test and replace the flyback transformer in that chassis, but that should be done by a qualified tech experienced in RCA projection sets.
