If it's not then a house call is your only choice due to the size and weight of your television.

Tip

RCA, CRT Projection TV, ITC222 chassis Faults - models D52W.., D40W.., D56W..,...


RCA, CRT Projection TV, ITC222 chassis Faults - models D52W.., D40W.., D56W.., D61W..
· Symptom: No Convergence, Picture is bowed and distorted, colors don’t align.
The Fuse for the convergence power supply has blown
You'll also notice that the convergence settings have disappeared from the on screen menu. The fuse likely blew because of a fault on the convergence board. If you've never done soldering or dismantled a TV before this is probably not the best place to start. The back cover needs to be removed and the fuse (see picture) identified, the deflection/power supply board needs to be unplugged (label or mark all connectors beforehand) and flipped over and the fuse checked/replaced. You need a soldering iron and solder ****** or solder wick and a multi-meter to check the fuse. If you want to tackle it yourself see attached image for reference or get a quote from a repair shop (approx $200-$300 Total) the convergence board may also need repair.



  • Symptom: Dead Set - TV Tries to Start or intermittent dead.

The set could be in shut down mode due to a fault detected in the power supply, vertical or horizontal deflection circuits.
The common problems with this chassis that will cause a dead set or intermittent dead set symptom are, bad power supply capacitors, bad flyback, bad HV cap in horizontal output circuit and cold solders (on opposite side of board) especially under the flyback area. To gain access to replace any of these parts the back cover needs to be removed and the deflection/power supply board needs to be unplugged (label or mark all connectors beforehand) and flipped over.
These are only the most common problems and it could be any number of other faults.
If you have electronic (TV) repair experience check the items mentioned (see picture), otherwise it's best to seek a qualified RCA tech for an estimate/service call.

· Symptom: Erratic operation of set – turns off by self, the volume or channel changes by self or on screen menu appears intermittently.

Switches on the front panel assembly (FPA) problem.
What happens with this model is the FPA switches (one or more) start to conduct just as if someone was pressing the buttons. This in effect locks up the system control or causes it to initiate erratic commands.
The way to determine if the FPA is bad is to remove it by unplugging from set. This requires front panel disassembly.
Note: The remote will still work with the FPA removed so the set can be tested.

Hope this helped, johnnydiode, Fixya.

Why am I starting to see black lines on the screen? I had this tv for only three years. Second protron worked for two years then all of a sudden it lost all power and has not worked since, can you explain...


yes. power supply may have overheated. your probably have bad capacitors and they need to be replaced. your screen may have caused the power supply to work too hard and it burned up

My KP-65xbr10w appears dead no life when plugged in.


If you have no indication of power you may have lost all of the voltages to your power supply, including the 5 VDC standby voltage. I am not sure if you can get a new G board, but you should be able to get the individual components that you need. I would look for the cause of the power supply failure first, and I think I would look at your Horzontal Output Transistor. I am thinking it is Q501, Q401 or something like that. I have repaired many of these and the HOT is most likely the problem. A shorted HOT would cause the power supply fusables to blow and the entire set would appear to be dead.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

Thanks for using FixYa

RCA P52960YX1 power supply dead - can I replace this myself?


Ok, Look, you can do this. Just take care when desolder any electronic part. ( position). mostly in capacitor ( - + location). You can buy a : power supply kit for ctc169 chassis. But maybe don't need replace all parts, just replace 2 small electrolytic capacitor 2.2uf 100v and 39uf 100v and ready...I hope this will help you. Thank you !!
