    thanks for the link but they do not have that manual either. I was trying to find out if the sd-p50a5-k and sd-p50a3 power supplys are the same.

    I removed the power supply board that was intermittant and resolderd all the tracks and componants and now the tv comes up with the green power light but goes into what looks like a power protection with the red led on the power supply board lighting up. any suggestions on how to find out what may be causing this?

Red lamp light on solid WD-52525

I will give this a shot and I don't work on TV's but it may help. If the error code is referring to ballast and you think about the ballast in a a flourscent light (essentially a large capacitor) that would indicate "the" ballast (and it could look like anything) may be (is?) defective.

If you have a diagram and / or a schematic in the manual and you can "figger" out what the ballast is physically you can test it. My guess is the ballast is between the input power and "other" electronic components. If you have reasonable accessability to the innards I would suggest starting by checking power from immediately after the input source, looking at the schematic, for values.

If I had to guess it should be the ballast or a component that controls voltage to or from the ballast. These would be immediately after or behind.

But if all voltages check okay (to the schematic) in that area you could have a problem further down the line...essentially an intelligent chip that regulates xy or z that is defective.

Assuming you have reasonable skill soldering (and unsoldering) and the schematic you should be able to find the problem but without a schematic you will be limited to finding and replacing the ballast (probably not all that expensive) and then seeing if it solves the problem or not...if not and you get a new error code you can repeat the process. In general the error codes gives (once interpreted correctly - beware sometimes what the words say is not what they mean) the correct failure mode (but not always the specific problem to draw a distinction). I

If you do not have a schematic check the mfg website...(that's a maybe as many sites do not have one but you might also try an internet search stating your specific model. You might get lucky.)

This is the logical approach. You might also want to add your model number et al. This will give you a better shot at finding someone with specific expertise on your unit. Most of these types of problems (as in what I do) or seen over and over again if you work in a specific field. You may get an instant answer meaning someone has already seen the problem with your unit.

Hope this helps....Tango

How to Fix X-Ray Protection Circuit

Some x-ray protection circuits would get voltage reference from the horizontal output. When a malfunction cause it to produce higher voltage, the circuit will shut it down. Look at the schematic carefully, and try to analize how the x-ray protection works. You can email me the section of the schematic that has the x-ray protection circuit, and I can help you better on solving the problem. I have worked on TV for several years, but I don't remember every model. My email is

THOMSON 40KW413 Rear Projection TV

Hello Perthi,

From what you have said, it can be surmised that a component has suffered a catastrophic thermal event (burnt up).

First I would suggest you get a schematic for the TV (if you plan on doing any work on the set yourself)

If you are not (the do it yourself type) then at least open up the set (powerd off and unplugged) and visually inspect the circuit boards and components to find any signs of thermally damaged (darkened and or burnt) components.

Check for blown fuses, cracks, and holes in components (stuff like this).

Once that is done, write down what happened, and then call a local TV repair shop (if you are not going to do it yourself) and have them make a house call to check your TV. Get an estimate and then decide your next course of action.

Now for my usual warning:

If you have a background in electronics, you know what equipment you will need to troubleshoot this problem, so I don't need to reinvent the wheel in this case, but I would still tell you that you need a schematic to do any proper kind of troubleshooting. If you do not have a background in electronics, please take your set to a qualified TV repair shop or have a qualified TV technician come to your place to examine the TV and give you an estimate of the cost of repair.

Thank you,
I hope this helps,

RCA P52940 Television

The P52940 uses the CTC195 series main chassis. The most common reason for the set not to start up is a shorted flyback (high voltage) transformer. The set actually does try to start, but the computer immediately detects the extra current drawn by the shorted flyback and instantly shuts the set back off. The chassis should be checked and the flyback replaced by a qualified tech familiar with RCA projection TV's.
