HD52W67 ITC222A Power On error codes

I'm retired on a fixed income and need to find out if it's worth fixing, I've presumed it isn't.
Short story, quick question is... is there a list of error codes available for this television?

Here's the long story, with every detail I can think of, if anyone with knowledge is willing to plow through it...

All of this happened about a year ago. To my best recollection...
The RCA television above had been used for approximately 18 months, daily, including frequently with computer through DVI connection for primarily downloaded videos. I did play flight simulator on it, but hadn't for over a year before the failure The television was used at the native 1080i resolution as ws the computer's video card.
The video card failed on the computer. The computer was not actively feeding the television but the DVI cable was physically connected.The card did smell burnt but was not visibly altered in any way. There was zero damage to the computer's mother board or its Sony monitor.
The television continued to work for several days, maybe a week, don't remember.
I had physically of course disconnected the DVI cable from the video card at the time of the card failure.
A few days later, an Error Message and some code came up, but by the time I realized what the bleep was going on, the message was gone, I hadn't written it down, the lamps were out and I've never gotten them to light since then.
The power light comes on the front panel of the tv comes on any time the power is connected. It does not blink, it stays on constantly. The front panel power button does work, as does the remote control power button.
I've had it disconnected for months between attempts at this point, but nothing changes, and the front panel power button lights the isntant I plug it in, but no picture.
There is no click when plugging in, but there is an audible click when buttons on remote are pushed. Tv does turn off and on with both front panel and remote power buttons.
The power button flickers rapidly with any button press on the remote control.
Reading of flyback transformer failures here, I have removed the back panel (out of warranty), and there is no smell and no visible signs of anything fried. The flyback visibly is as new.
I keep hoping it just needs a memory reset or something... but have seen no mention anywhere of that being possible.
Even the error codes might help, I think if I saw them listed I'd remember which one it was. It mentioned the DVI port, but I don't remember the rest.
Sorry for the novel length post, but I've tried to anticipate the relevant questions and issues.

Hello jrdement

This does sound like it could be an IHVT (Integrated High Voltage Transformer "flyback") problem. I have some questions to ask.

1) When you try to turn the TV on do you see the CRTs filaments light up? (These are the heaters that heat up the cathodes of the CRTs to allow for the creation of the electron beam)

2) Do you have any high voltage on the CRTs anode? (you will have to check this with a high voltage probe)

3) Did you see any puffy or exploded capacitors?

4) Did you smell and burnt components?

Please answer these questions, they will help me have some idea of what is going on.

I hope this helps,

Thank you,

Shuttle83

    Hello jrdement

    This actually tells me a lot. The fact that you do not have filament power says that your voltage supply to the filament has malfunctioned. What I need for you to do is to unplug the TV set and look for a fuse on the circuit board and see if it is blown, then I need for you to use a multimeter set to resistance and measure the fuse to make sure it is ok. Once that is done you will need to check the collector of the horizontal output transistor to make sure it is not shorted to ground. If you can not perform any of these tasks, I would suggest that you have a TV repair person troubleshoot this for you. The signs are showing power supply failure.

    Thank you,

Thats a deflection issue. You can get the ITC222A deflection board Bar code PSB-260 from www.tvrepairworld.com which will usually fix the 3 blink error on that model

Hd52w67 replaced fuce in bottom left to fix convertion problem worked for 5 min then blew somthing is drawing to much current can you trell me where to purh. convergance board


Unless you replaced the DL231 and the CL230 plus resoldered the flyback and vertical IC the fuse will continue to blow. The ITC222 and ITC222a convergence option missing repair kit from www.tvrepairworld.com contains those components and the CD with instructions. They also have circuit boards for your RCA.

RCA R52WH74 (ITC222A Chassis)


no the board that has the FL231 on is the ITC222 deflection board. The other board is above the chassis in a seperate frame that runs across the set the convergence power supply is the board on the left above the board where the fL231 is. Yes the ITC222 and ITC222A are the same chassis. As for the service manual that site should have the service manual under the thomson category as the ITC 222 chassis is actually a thomson chassis made for RCA.

Convergence


Okay, usually the parts that go bad to make the convergence option drop from the menu are the following. Fusible Link (FL1231) Diode (DP1231) and capacitor ( C1230) the numbers in parenthesis are the actual component locations on the board. These items fail causing the set to think its a direct view set instead of a projection unit.
