I have a Toshiba 62 inch Flat screen HDTV model 62HM15I do not know anything about tv's, but there is something internal that is preventing the unit from displaying a picture. If you know anything about repairing tv's, this could be an easy fix for you. I have replaced the bulb, ballast, and color wheel already. thanks, Jim

TR,
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!

All you do is remove the screws from the panel in the back and pull the bulb assembley out.

If your model number is 55PP935217 you dont have a ballast. You have a rear projection with 3 CRts . Please let me know if thats the correct model number and what your symptons are. I will be able to help you get what ever part youre needing.

The buzzing is most likely the fan. A low volume intermittent screeching (like when a small motor needs lubricant) is probably the light engine. It also may have a really wacky picture with the sound.
