Question about Toshiba 52HM95 52" HDTV Projection Television

52HM95 Toshiba DLP

I am hearing a noise in the back of tv and I know it is the color wheel I am just wondering is there anyway I could replace it on my own or do I need to take it to someone and get it fixed.  I just recently had to get my lamp fixed in the tv, I didn't know that it goes out so frequently.  After I had it fixed I realized, once I called toshiba, that I had an extended warranty on the lamp and that it only takes about 5 or 10 minutes to install, this is after I already spent 500 dollars to a tv repair man in the area to repair it.  So I really can't afford to pay 500 more dollars to repair the color wheel I mean I could just purchase another tv for as much money as I would be putting in it.  What is the price of the color wheel and is it difficult to put in?  If I had to take it to a tv repair shop what should I be looking at as far as the price?  I don't want someone to get over on me again like he did with the lamp, charging me 127 dollars for installation time.  If you have any solutions or know anything about the prices or anyone in the north carolina area that could install it for a reasonable price let me know?

    Thanks for your help!  I don't understand what you mean by having it rebuilt?  I thought it was just a part that you purchased and put in?

    I am looking for a source to replace only the color wheel on this model. It
    screamed so loud that I couldn't turn up the volume enough to cover it
    up. My service tech says that Toshiba said he has to replace the whole
    color engine, which we both disagree with. Any ideas where I can get this? Otherwise he said it would be over $900 for the repair, and I only paid $850 for the whole thing!

    Our TV started having problems with the color wheel last October, 2007 after only 2 years of ownership. Our repairman said it was the colorwheel. I sent a letter to Toshiba asking if they could help and they said no, it was out of warranty. We have listened to the high pitch noise for almost 10 months now and today the color finally failed and the lamp quit working. We have been told it would cost around $800 to fix but that part is on back order, sounds like it could be on back order a long time. I am very disappointed with Toshiba and will not be looking at buying another Toshiba product. This TV cost us $2500 and has last not even 3 years, very disappointing.

    I replaced my lamp about 8 months ago, and now the lamp fan is making noise. I took the back cover off, removed the lamp and cleaned the fan and area surrounding it with a soft bristle vacuum brush. I also blew out any remaining dust or debris with compressed air. After reinstalling everything, it is still making noise. How can I tell if I need to replace the lamp fan or the color wheel?

    I am so devasted to hear how many people have the same problem with their Toshiba TV's. When we first started hearing the loud screaching sound about 3 months ago (we had only owned it a year), we were told it was most likely the bulb, even though the color would turn green and pink and the picture eventually completely went out. Once we replaced the bulb, it seemed to be OK for a while. Then the screaching came back, the color went crazy and the picture completely went out again. I know it's the color wheel and there are none to be had anywhere. I plan on contacting Toshiba, the Better Business Bureau and and an attorney to tell them my story. There is already a class action law suite against Toshiba on this model for problems with the bulbs and with any luck, we'll get another one for this problem with the color wheel. At the very least I will never buy a Toshiba again!

A color wheel is not so difficult to put in - it's dismantling the unit to get to the color wheel.. While $500 seems to me a little bit high for your area it might have been about average and $127 for labor is probably a pretty good deal if he did this as an in-home repair figuring his time installing the new lamp into the housing and the housing into the unit, plus travel time to and from the shop.
The noise you're experiencing could be the fan and not the color wheel.. Easiest way to tell is take the back off and as the set is turned off unplug the flat ribbon cable going to the color wheel. If the noise quits immediately it's color wheel if not guess what - it's the cooling fan...
A shop would be the only I would know to advise you to have this repaired - I'm a CET myself and it's a pretty difficult task taking one of those DLP format projectors apart. And I've been at this more than twenty years. But you can test whether or not that's your problem and go from there.. If you have to have the color wheel replaced have the tech look into having it rebuilt and see if Tri-State Module services that wheel.
A good way to research techs in your area is with NESDA (National Electronic Service Dealers Association) here's a link:

Hope this helps!

    The color wheel is made-up of several smaller controlled parts. not least of which is the motor assembly and sppre controller circuit. The "color wheel" itself is press fitted to these other assemblies and all of it can be rebuilt rather than just replaced like a module. Tri-State-Module has taken to rebuild some models, but I'm not sure if they service this particular wheel - it's worth looking into because it can save up to half the cost of a new one...
