Red lamp light on solid WD-52525

First signs of the problem I was watching tv and on the top of the screen there white swirls coming about a third of the way down.I went down stairs when I came back tv was off.Turned it on and it said no signal tv will shut off in 1 min. it shut off I turned it on then all I had was a blue screen with white lines threw the center.I then replaced the bulb with a new on did the same thing only now shaky blue with the white.OK now screen don't light up at all and now I have cover off and I can see the bulb light up for about 5 or so seconds screen really don't light at all, then tv shut down and solid red light.Checked error codes has a 34.I see some say check ballast I have a service manual.and a volt meter so if you say check the ballast tell me how.I am a autotech and pretty handy and need to fix my own tv I live in a small town and can't get any one to come and fix.

    Any cap that is visibly bulging is probably already degraded at least 50%. The ones that cause the red lamp issue are the pair of 3300 uF's that are on the left side of the board (left of the big metal heat sink). When I did the repair, I bought 3300 uF's from mouser:

    Part Number: 647-UHE1A332MHD
    Voltage: 10V
    Capacitance: 3300uF

    If the cluster of four 1000 uF's are swollen too, you should probably replace those as well. They can be bought from Radio Shack (the higher voltage rating is OK).

Error 34 is a bad light engine and from what you've explained it sounds like a failure in the lcd as it went... Hitachi 50V500 has a problem with LE's too and they glow red on the screen before their eminent failure... It's not a meter you need on this one and I wouldn't tackle it yourself - just like I wouldn't even think of replacing the engine in my truck. Find a reliable repair center and take it to them..

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

Turned on TV and had no picture. Now when I reset I get green blinking light then solid green status. After about 30 seconded red lamp light comes on. Is there a solution?


Your lamp is defective, incorrectly installed, or the cooling fan under the lamp is not cooling the lamp for some reason. Service that area.

Mitsubishi WD 52525 lamp replaced, no picture, red light


You have to take the TV apart. Pull the electrical chassis out and look for bad electrolytic caps on the boards. The red LED probably means the 2 - 3300UF caps on the power supply board are bad. You can tell if they are bad by the fact that their tops are puffed up and they may or may not be leaking brown fluid. Compare them against the other caps on the boards and you will see how they have flat tops.

BUT before you take the TV apart you can check the error codes by pushing "menu" and "Device" at the same time and holding for about 10 seconds. The status light will blink two numbers. ex. one flash pause two flashes is 12 Error Code Probable Cause

12 No error detected
22 Recovery from momentary Reset
32 Lamp Cover open
33 Air Filter Cover open
34 Lamp abnormality
35 Chassis Fan failure
36 Exhaust (Back Cover) or Lamp Ballast Fan failure
37 Engine (DMD or Lamp) Fan failure
38 Excess Lamp Temperature
39 Excess DMD Temperature
41 Short Detected
44 DVI Cable (between Chassis and Engine) disconnected


or use this table -

You can buy replacement caps from Mouser electronics online. There are plenty of solutions detailing how to do this already posted.

I have a mitsubishi WD-52525 DLP Tv; I replaced the lamp, powered on the system, I hear the fan go on, the green wait light goes solid after a few seconds and a few minutes later the lamp light goes solid...


Chances are the lamp is not bad. Is the lamp door reseated properly? The is an interlock on that door that must be activated in order for the set to turn on. If the unit was woking before the lamp went out this may be the problem
