So you're saying the color wheel sensor was over heating, causing the wheel to spin erratically?

Eddie

Hey Joe, how did it explode and where did you get your replacement lamp? Is it a Philips?

Eddie

As far as I know, you can source the part from a manufacturer or parts distributor like parts store.
--or--
You can try buying a used HP XP7030 unit. That might even be cheaper than buying new color wheel!

Eddie

That's bazaar! Any other symptoms besides just not turning on? Noises? Picture problems before/after? Usually there are more symptoms than just turning on and then off. Or you have a saboteur at home!

Eddie

Well, ballasts aren't that expensive in terms of DLP repair. You could always try to find parts online. Check DM first. If you're low on cash and don't want to invest just yet, keep reading forums on the web or here on our site. I'm almost certain it's the ballast, but I'm not there to check it out....

Eddie

Kent, the lamp has nothing to do with the coloration, only the intensity of the picture. A coloration problem may be something else all together. If you're saying it's dark AND blue, you might have a combination of problems. The firs thing to really check out is that ballast though. There are a numb...

Eddie

Possibly a color wheel. Not sure though. Obviously you're a tech, so I suggest double checking that color wheel to see if it's the cause. Try and listen for noises during operation, but you said the colors are varying while shutting down. I don't think that's common and definitely indicative of the ...

Eddie

.... Just wondering if this HUMMING AND WHIRLEE-SOUND has anything to do with the cooling fan??? I have been reading info on the Samsung website that advises the sound could be due to this problem. Again.... HELP! HELP! HELP! You're sure it's not the color wheel? Where did you purchase the color wh...

Eddie

That is strange. I'll do a little more research on it.

Eddie

I am moving this post.

Eddie

Mike, the clear thing to remember about DLP lighting technology is that they are gas lamps. They aren't your typical house light bulbs (and even those are being phased out these days). If the lamp is having trouble turning on, there are a few things that can be wrong: The first is obviously the lamp...

Eddie

I hope he gave you a refund! You don't take your TV to get a new color wheel and have it coming out broken! That shouldn't happen! Tell me the name of that company so I never refer any work to that fellow! No sound no picture can be a number of things, especially when all three lights are blinking.....

Eddie

Do you have any other pictures? I am not convinced it's your digital board or DMD board. It could just be the color wheel. If you're getting funky colors, than that's a clear indication that the color wheel is failing. It doesn't have to make a whirring or loud whine to be indicative of failing. Som...

Eddie

Please try to keep your posts in the same discussion otherwise it gets messy. I'm going to move this to your other posts!

Eddie

Jeff, Has your television been moved around recently? Have you had any service done to it? This isn't an common occurrence, but it sounds like your back reflector is out of alignment, or perhaps falling a bit. Unfortunately I don't have any photos to show you, but taking apart the back of your telev...

Eddie

Harry, do you have a Sharp AND an RCA?

Eddie

What is the exact model for that color wheel part? Where did you buy it? Sometimes people sell a placement part instead of the OEM part. That has its failings too with compatibility. I generally steer people away from non-OEM, or no-name brand manufacturers. Got a picture of what your TV is doing?

Eddie

The ballast's main job is to supply enough power to the lamp for ignition and to keep the thing on. A weak ballast will often times not ignite the lamp at all, or simply not maintain enough wattage to the lamp causing it to appear dimmer than normal. The lamp, in turn, sucks up as much power as the ...

Eddie

A novice can certainly work on the television alone, but it will take some time, and learning on your part. I'm curious as to why it doesn't even turn on anymore though. I wonder if you have a power supply board failure. It's possible that the power surge from a few years ago was the source of your ...

Eddie

Sometimes that happens though when you purchase from a non-authorized company or purchase a non-OEM part. You've always got to check out the company you're dealing with and you're probably the first person to say dlp lamps express is decent. I personally don't trust any company that I can't call, or...

Eddie

I saw this post and thought, "Oh, no, another green blob on a Sony."

Eddie

Is that picture of the screen a picture of a TV program or commercial? Or is the screen showing up like that before it goes to black?! First instinct is DMD board. Doesn't seem like it would be an easy fix. Any other information like: What was happening before this started happening? Did you replace...

Eddie

Wow, I'm not really sure, but it could possibly be a DMD board issue. This is definitely NOT a bulb issue. You may need a new one later, but I'd focus on what's causing the problem of the lines... and that's most likely a DMD board or DMD chip. Consequently, what's the model of your television? I ca...

Eddie

Clarification from Yaya0525: Glad to be able to share the experience and possibly help anyone who might just be as 'challenged' as I. Thanks again! For the record, the 1st replacement wheel had a bad wheel, it wobbled and screeched terribly when running and the 2nd replacement ran smoothly and fine ...

Eddie

Where did you get that service manual!? Do you think I can get a copy of it?

Eddie

This is a post about a consumer who contacted me through the board. They had purchased a new color wheel and was still having color issues. I had told him to check a number of things, but I had forgotten one important thing: CN810. ------Yaya0525------ Ok Eddie, I just replaced the color wheel and n...

Eddie

hey 54321, replacing a color wheel isn't really hard, it's just a lengthy process. I don't know of any service manuals out there, but you can search our blog here at fixyourdlp.com and see how we've replaced some color wheels... it'll give you a pretty good idea on how to do it!

Eddie

Did you try that HD satellite box? I'm still a little puzzled as to why there's no video if you've got everything plugged in okay. I'd think it would be the set top box if you get some sort of picture and read out from the box at all. My other suspicion is that it could be the video board... very sl...

Eddie

How do you know it's burnt or blown? Do you have a photo to show us? Can you describe it more in detail, please? thanks guys but i can not invest another $1.00 on this dlp. and my HLS4676sx is dead also. I found a blown/burnt capacitor(i think thats what it is) on the upper left corner of the DMD bo...

Eddie

This is in the wrong place. It should be in the RPTV section. I'm going to merge it with the color wheel posts.

Eddie

The RCA lights of doom, as they were, could be a number or problems. I would have suggested a Philips lamp in that television, but definitely pull the lamp out and inspect it visually before purchasing a new lamp. Some very common problems with RCAs is the power supply going bad on you. The capacito...

Eddie

Hi Jose, Is there anyway you can take a photo of the TV? Is it exactly half of the picture? Is the picture only being lit up on the left side and not on the right or are you not getting picture period? These things will help narrow down the possibilities. Also, what's the exact model number of the u...

Eddie

Hello Labrocca, This issue has been covered before. Please check this post out to see if it helps you: http://www.fixyourdlp.com/forum/viewtopic.php?f=12&t=846 Unfortunately, I honestly can't solve your problem without a little more information. Did you take the lamp out? How does it look? Any sound...

Eddie

Hey Paul, The light tunnel is a little optical rectangular tube that runs from the wheel to the optical mirrors that lead to the DMD chip. The tube itself has mirrors inside glued on to each of the sides. When a light tunnel "collapses" the glue has worn out and the mirrors are slowly falling down, ...

Eddie

Dave, you're right. There's no definitive answer if you can't diagnose the problem yourself, but the lamp is usually the first thing to go out and the first thing people tend to replace. So do you take it to a repair shop or replace the lamp. Let's weigh the options and ask yourself a few questions ...

Eddie

Sounds like you got a bad unit from the get go. The problem was probably the light engine all along, and using a service center to replace parts is like taking your chances at the junk yard. Unless they're using new, OEM parts, I don't see how you could have ended up in this mess. Not saying all tec...

Eddie

Just a tip:

The tech usually charges $50-100 to come out, but will put that money toward the repair (most techs do this). Just to be straight though, if the problem is going to cost more than $400 including parts/labor, be wary of the costs! They might try to squeeze you for more.

Eddie

I disagree.

The issue could possibly be a faulty sensor that's tell the TV it's over heating. Start by cleaning out the filters with compressed air and see if that helps a bit. If the lamp is coming on, it could be a number of things beside the DMD board.

Eddie

Gremlins.... jk! Theres no real way to test the ballast unless you have a high voltage multimeter. You see the ballast does 2 things... 1. It ignites the lamp 2. It maintains power levels and feeds it to the lamp. The lamp then consumes as much as it needs. The trouble is that the Toshibas use direc...

Eddie

There's no liquid in the TV, that's the problem. I'd start by checking the lamp like ovadoggvo says. That's a possibility too. Otherwise, I think it looks like it's seated wrong--but only a good repair tech will be able to tell you what's actually wrong with it!

Eddie

Ever play Fat Princess? That's currently my favorite game!

Eddie

Sounds like it may be a light tunnel, but I don't have as much experience with RCAs... Jack just emailed me: I just took the back off of my set. After removing the color wheel , I can clearly see the mirrors in the light tunnel have collapsed. If you have some pictures, that would be awesome to see ...

Eddie

I'm moving this post to the correct spot.

Eddie

Not for Panasonic as far as I know, but maybe. The Toshibas had law suits, so did the Sonys. It may just be a bad temp sensor... for all your troubles, if it eventually comes on, I wouldn't sink too much money into fixing it. You might be able to find someone to part with their old TV or even find t...

Eddie

You'll need to check the capacitors as they are usually the first to blow if something goes bad. Check to see if they bulge on the top. If there are caps, remove them to check.

Eddie

If you took it apart, you can put it back together. I don't think there's a reset code, but possible the code that came up wasn't the problem in the first place.

Eddie

This TV uses three LEDs and I don't know if there's a way to replace them. I believe they are surface mounted. The only way to replace them is to replace the entire engine. But let's look at the problem again. Make sure it's the LEDs that is causing the problem. It could very well be the power suppl...

Eddie

I have a 5 disc Panasonic DVD player that up-converts to 1080p. It's a pretty sweet device and the upconversion was pretty good before the new generations came out. After I moved a few months ago I started having some issues with the unit. I found it on the bargain rack at Best Buy for $90 bucks com...

Eddie

I've moved this to the cable boxes forum for the time being. If we find that it's the television, I'll move it back!
