ATC336 Power Supply Issue?

Have you seen this power supply problem mistaken for a bad DM3x module? My set comes on, then a solid LED front panel for a few seconds, five blinks, then solid again. Occassionally it will blink 5 more times a couple minutes later, but I think that's just telling me the same issue. The LED is unresponsive the entire time too - must unplug to turn off. Fans, nor the color wheel try to spin. From what I can see, nothing beyond a red light coming on within the DM3x is going on. I don't think the tv is getting anything past the DM3x modue, but I still think it could be the power supply. I'm going to remove my power supply hopefully within the next couple days and check the caps you've suggested. I've done plenty of solder work on small electronic components, but nothing like this yet. I think my biggest issue is going to be locating the new caps. You said they can be purchased at Radio Shack, what exactly am I looking for? Thanks so much for your time, and any other advice you have.

Ws-48313 no power


This model is equipped with a keyboard lock feature; this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds. 2. (Power LED may be on after plug in) check for no less than 4.4 volts DC at pin 3 of PC9A21 on the Power PCB, if low or missing replace PC9A21 part # 268P058020. Hope this helps if not let me know and I will go further

I have a hitachi 60UX58B. It went pow.


If it is totally dead, then this is likely a power supply issue. If the front panel LED comes on, but nothing else, perhaps there is a problem on the deflection board, or perhaps the convergence chips died and shut down the set.

Thats a common problem with the RCA ATC336 Power supply when the capacitors fail on the AC in power board. You can get the repair kit at the following link which will usually repair that symptom.

There are instructions to replace the lamp in the user's manual. The light comes up but if the lamp has now already several hours of use the resistance of the lamp increases and shut down the power supply of the lamp. Second, the lamp power supply could be bad too, but lets be optimistic and just replace the lamp first.

RCA P61960 projection screen. no picture, no sound. tries but shuts off.


It will depend on the Chassis number you have but it sounds like a bad Deflection module or a bad Convergence power supply module. The Convergence Power supply module is on the left looking from the back mounted above the deflection module. On newer models the picture tubes can short and put these sets into shut down mode ( Three Trys). Start by unplugging the CRT modules off the neck of the tubes one at a time. If it doesn't come on you have eliminated the tubes. There will be a Red and Black set of wires from the deflection module to the convergence power supply module. Unplug it. If it fires up then it's the convergence power supply module. If not it will probably be the deflection module. The flayback transformer is a common problem along with several bad caps towards the front of the board. Let me know if this fixes it.

ATC336 Power Supply


Yes the symptoms of bad capacitors on the Power supply can mimic the symptoms of a failed DM3. Its alot better to try the capacitor change first, as they are a common source of failure and the price of the DM3 is very exspensive.

I would try the power supply first as the ATC336 has a history of the bad power supply boards.If the power supply doesnt fix it then I would think it may possibly be the ballast
