Question about Mitsubishi WD-52327 52" Rear Projection HDTV-Ready Television

1 Answer

Dull colors, dim images

I just replaced the DLP lamp which was definitely gone. However, I had my CRT set sitting next to the Mits, and the CRT picture is much brighter, especially the whites. No amount of adjusting seems to make things brighter.

Another tech on this forum suggested removing and cleaning the screen of dust, and there had been plenty of that around the TV. Is there another suggestion before I try to remove and clean the screen?

    The replacement lamp came from DLPXPress, and it is the same as the original (Osram). I can't compare to the old lamp which has failed completely, but the picture initially semed dimmer than before the lampo change. I reset the unit to factory defaults which made things better. The default brightness setting is full on (63). I would have noticed the difference in picture even without the comparison which was striking.



    Thanks for talking me out of removing the screen. Still, I'd like to see some "ideal" settings for this model TV to see how that looks. How can I clean the mirror behind the screen?

    I had a warranty on Samsung DLP and they changed the lamp 4 months ago along with the ballast. The picture wasn't bright and the lamp blew so I replaced it using an osram bought on line for $139.. My picture is excellent again. I believe the repair co. that replaced the lamp used an old one from another tv.

Where did you buy the lamp at? Does it look the same or worse than when the old lamp was in there and working? Is there a big difference or if there wasnt another tv sitting next to it mabe you wouldnt notice? Also you dont need to clean the screen, that could damage it. If you are going to clean anything you will need to clean the mirror behind the screen.

    Do you know what company you bought the lamp from? was it straight from mitsu or another vender? Also to clean the mirror you will still most likely need to take the screen off but you do not want to clean the inside of the screen because its not really a screen its a lense and you will damage it significantlly, you only want to clean the mirror. As for settings the factory default is what I would reccomend. theres alot of hype about perfect settings and all that but to be honest with you i dont see a difference and I look at anywhere from 10 to 20 tv's a day in my shop and field.

I have a philps 51pw9303 digital HDTV monitor. The picture has gotten very dull and dark. The colors are very dim and dull. Is this a bulb problem?


Check the convergence settings if necessary, try to check the bulb cause sometimes is getting weak. If you want to replace the bulb don't forget to reset the lamp hour meter. Let me know your feedback. Good day and God bless. Hope it helps.

LINES THROUGHOUT SCREEN AND COLOR NOT SO CLEAR AND BRIGHT. Vertical lines on screen and the color is very dull. It's not bright. Is it somehting simple to fix or forget it...? Thanks


It sounds like you are at the end of the useful life of your unit. It is a CRT projection unit and when the colors get dull, picture gets dim and especially when you have lines on the screen indicating retrace problems the CRTs are shot. Cost to replace would be more than new. I would recommend a DLP. Of all the schemes out there I think they are the best looking, least prone to breakdowns and most cost effective. Let me know if you need more help. Thanks for using FixYa and for the generous rating.

MY SAMSUNG DLP MN HLP6163W PICUTURE HAS FADED


If you have had this unit for awhile it could just be the lamp. If the image does'nt brighten up you may have an issue with the light path. The color wheel produces the color. If there was an issue with the color wheel you would most likely have a black and white image.

Samsung dlp HLT5676SX problem


There is a mirror system and lense within, the mirror is much harder to get to... there is a chance when you were changing the bulb your hand smudged the lense... look inside when you inserted the lamp and check the lamp itself...

This is more for information question. Dose Mitsubishi have a DLP TV that dose not use a color wheel and lamp where you can get 3D?


Yes, Mitsubishi did make a DLP that did not use a color wheel, but I am not sure if they still make it. It would be in the Diamond series and it uses 3 image units. I believe this was a professional set and was very expensive. You may have to ask around at you local electronics store to see if Mits still make this set.

I hope that this helps.

Ballast or color wheel next?


The color wheel will normally spin-up even for a brief moment when the set is powered up. I have not seen a color wheel go out with a lamp. I have seen a ballast go bad with a lamp. I would replace the ballast first. You did not state wheather the color wheel was noisy or not. On the Samsung DLP, the color wheel is normally very noisy before it is gone. I hope this will help you.

My DLP TV made a loud popping sound then went off


first. unplug the set for 5 minutes and see if it will reboot. if it does not the you have 2 problems, the chassis is also bad. next open the lamp door cover, it is behind the speaker grill, and behind the lamp door.
take out the lamp and see if it has broken on the inside if it has it needs to be replaced. mits will send you one i believe it is about 100.00 the number is 915P020010. if the lamp looks ok then the color wheel has probably fallen apart.if this is the case the light engine need to be repaired. check out www.tv-techs.com

Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • 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.

f0900cb.jpg
Here is a quick test....

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

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

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

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Dull picture


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.
