I believe i have the same problem as others on your list. my power cuts off intermittently and can turn back on after being off for awhile. How do I send the power supply to you for soldering repair? Any special instructions for removing the power supply? Thank you

Re: Power Supply repair
SHUT YOUR UNIT DOWN NOW. We don't want further and more expensive repairs to be needed because of the threat of the domino effect to boards downline from this one, that not remedying this situation carries with it, every moment it has warmed up and is running, in this intermittent condition.
This is a problem that is very widespread on this series of unit, and I have been 100% successful in remedying it so far, both on location and by doing the repair op on boards sent to me from many parts of the continent, and returned by me ready to go. This has been happening over and over and over again - many Pioneer Elite - and non-Elite - boards have been sent my way, with owners totally blitzed to have their sets up and running faithfully again, after the repair.
Please call me for details and leave me contact info for you, and also send me a request via email, at bob at imageperfection dot com.
I am not at home and can't reach for that stuff to email you, which I can do later once I'm home again later today.

Try unplugging power cord for a couple of hours then reboot. If that does not help you may need a new power supply board. But first try wiggling and jiggling the set to see if there is some intermittent connection inside. Jiggling sometimes gets it going again.
You can google for power supply board replacements. For USA, shopjimmy.com is a good supplyier but you can find in your own country easily. They are not expensive although it is questionable about repairing a small set like this as price of new models keeps coming down lower and lower.
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.
Samsung has had a issue with several models, with power supply going out. The clicking noise is what lets you know it is the power supply, it is teying to cut on but has not power from the board so it cuts off. I would call Samsung and see if your model happens to be listed as the models they are covering the power supply for, your exact model number is HCM553WX. If that model is not on the list of covered models, you can ask Samsung what to do, because parts for your tv are no longer available. Hope this helps. You can reach Samsung at 1-800-726-7864
This seems to be a problem in the Power Supply I would think. Either that or a fault that is overloading the PSU.
This means a trip to the repair shop.
Make sure ya get a firm "Quote" for tha fix before proceeding.
for using FixYa. You’ll need to reset the Projection TV and to reset it follow
1. Turn off the television and wait for 5 minutes.
2. After 5 minutes unplug the television power cord from the electrical outlet.
3. Let the television remain without power for more then 1 minute.
4. Plug the power cord back into the electrical outlet. If the television is
plugged into a power surge protector, remove it from there and plug it directly
into the wall outlet. Turn on the television. If the issue is resolved, then
the problem is with the power surge protector and not the television. If the issue is not resolved then this might
have happened due to over-voltage. Please check the power supply unit for
swollen/bulged capacitors and burnt wires/components on the power supply board
of your TV. You should try and turn off the TV for 8-10 hours to reset it. Please make sure to turn off and
unplug the TV for at least 1 hour (this will drain off current from
all components especially capacitors) before you perform any repairs. Also note
that the TV consists of very high voltages even when it is in OFF condition.
All this is only recommended if you have electrical expertise and know how to
Please do accept the solution if the issue is resolved or else revert for
Have Capacitors checked in the power relay circuit, also if you have young children who like to push the buttons on the front of the set make sure none of the buttons are sticking inward or stuck in a pushed in posistion. More then likely it might be caused by a faulty System control board which we call the signal board, or bad connections on the power supply, Have a tech check the connections on the Flyback transformer and the High Voltage Deflection Area on the HV Power supply. I believe you have Cold Solder Joints in the HV Power Supply.
This is the ITC 222 chassis. Most likely the problem is caused by capacitors on the power supply module part# 265324 which is no longer available. The module has to be repaired to the component level. Look for capacitors that are bulged at the top. I usually get around $250 for that repair (Carry In Only). There are also other causes but someone would have to troubleshoot the problem.
