Mitsubishi Caps cause dim Picture faulty capacitor issue in the WD-52525 does seem to be prevalent at the 3 yr mark. At the bottom of this long-winded comment is a link to another discussion forum similar to this one where we obtained the service manual, chassis replacement manual, and encouragement to attempt the repair ourselves. My husband and I are not experts by any means, but my husband did have the tools from previous electronics projects to solder. So we took a chance on looking for bad caps. And I am here to say that I’m so glad we did because there were 2 obviously swollen caps that were easy to replace. The picture is now even better than when the problem first occurred since we dusted the mirrors and screens while we were in there. NO WINDEX. Just a dry micro-fiber cloth did the trick. We'll probably do that annually going forward.

According to descriptions from several people, the symptoms and degrading image due to capacitor failure can take various forms. In our case, we had a lamp blow out 2 wks before the TV died. And I do mean blow out, not burn out. We didn't get any lamp replacement warning. It flat out blew the 1-yr old bulb to shards of glass inside the casing. We replaced the bulb with a brand new one like good stewards of a DLP HDTV should do. A mere couple of weeks later we watched the image degrade over the course of an hour through various stages until the new lamp simply wouldn't light anymore and there was a solid black screen and solid red lamp light even though the lamp itself was fine. The trouble-shooting diagnostics (pressing MENU and DEVICE buttons on the front panel) gave the 3-4 code indicating a lamp abnormality. But ultimately the problem was solved by replacing the C9A37 & C9A38 caps (both are 10V 3300M-M 105C). We did not have to do any repairs on lamp or ballast components. The cost of 2 new capacitors from Digi-Key including shipping was about $14.50.

Some folks have stated that they were able to do the repair without removing the power supply chassis from the back of the TV. That was not the case for us. It was a bit intimidating at first. But we disassembled everything, labeling as we went, so we could freely inspect and access all boards on the power supply. There are some tiny, very hard-to-reach connections between the power supply and the ballast. For this reason, I also recommend disassembling those ballast components from the frame. They're simply too fragile to force in a very tight space when reconnecting.

Lastly, I am still pleased with this TV. The color and clarity can not be rivaled in my opinion. Even after having gone through this, compared to the problems reported in some of the other threads on issues with whatever other brand name or model you pick, this is a relatively easy repair that can be DIY. This was why we went DLP in the first place. And it is why we will probably remain DLP fans until they aren't made anymore. But next time, we’ll go with an extended warranty for sure!

I do wish Mitsubishi would at least acknowledge the issue. I don't even expect any reimbursement, replacement, refund or anything like that. I'd just like to know that THEY know there's a simple problem to resolve and that they're doing something about it.

Thanks, I posted a question regarding a convergence failure earlier. I followed your previous advice and replaced the STK392-110 and STK392-150 chips and the RK62 resistor which was bad, however the...


RK62 in this model is a 2.7 ohm 1 watt resistor (per the Hitachi site).

Let me ask you a few questions--did you check all the protect resistors? Sometimes you get one that looks perfect and is open.

Second, are you trying to adjust with the Hitachi remote in the customer menu or the TECH menu?

If in the customer menu you may need to go into the TECH menu and adjust and save there--if you get into the TECH menu and blue will not adjust somewhere--you probably have a bad resistor somewhere.

This all sounds familiar--I bet I helped you before--

Mitsubishi WS-48511: can't adjust blue convergence


I am guessing that you did the convergence menu 1.CONVERGENCE MENU "MENU 2159, 4 FINE, 5 COARSE, 6 MISC
2. There are Fuses F9A04 & 05 that may be open.
3. If you do the self test do you come up with 2-2?
4. Self-test on threads here or at ctechnicians.com
5. If one or both fuses open you will need to change convergence amps and parts.(Kit)

Pitcher is dark and distorted like its pulling to one side


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Mitsubishi WD-62525 BLUE SCREEN NO PICTURE NO SOUND


I had the same problem and I found that it was 2 caps on the power supply board. I had both caps replaced and it worked perfect. While it is apart see if any other caps are bad( if they are puffed up in the center they are bad).

Dark background blue tint


Try the Magic Focus option on the menu screen found under "Picture". Make sure the TV is on for 20 minutes before activating this option. It is also best to run this when the room is dark.
