Question about Projection Televisions

1 Answer

I have a toshiba 52hmx85 for two years and just noticed a humming noise.I have heard it could be the color wheel.Should i just ignore it until it breaks or should i be worried about it now?And if it is the color wheel can you just replace the wheel or do you have to replace the ligh engine.And also is it hard to do?Could it also just be the fan?It makes a noise the entire time it is on even during cool down.

    I would like to do the work myself.I am an auto tech.and am good with tools and electrical problems.Tools are not a problem.I am just not sure if it is a fan or color wheel problem.I'm thinking color wheel from what i have read.Has anyone changed one before?

I'd worry about it now..that's a sure sign that there's a mechanical issue. do you intend to do this work yourself? what sort of documentation do you have? and also what sort of tools are at hand?

    well..changing one, and walking you through it online are two differing issues. You'll need a service manual, no doubts.

Color wheel price for a Toshiba 52HMX85?


Hello jjoana,

My shop charges the labor fee of $60.00 per hour and fraction of an hour. So a 1 hour 1 min job is charged as 2 hours. This is just the cost of labor. $60.00 is an average I took from 10 sampling of TV repair shops when I was developing my pricing scheme . I hope this gives you an idea of the labor charges, There maybe other fees attached, or depending on the shop the cost could be higher or lower.

I hope this helps,

Thank you,

I am wondering if this sound might be your color wheel spinning. The color wheel often makes a low humming noise as it spins. Try checking to see if this is not the source of your noise. You need the color wheel to generate the colors needed to turn the B&W picture generated by the DLP into a color picture.

Thank you,

Loud noise


I believe it is the color wheel. The motor might be going bad or it has dirt or dust in it.

I hope this helps
