the problem your having is a fan problem. when was the last time they were dusted? take some compressed air and spray the dust AWAY from the fans. make sure all the fans are working and you're all set.
I have a two year old Toshiba DLP 62HM95. I had to replace the lamp after about a year of use. That was no problem. I am now experiencing some other issues with the tv. I am not sure exactly what is wrong.
When I turn the tv on it makes a loud buzzing noise as it gets going. I'm thinking this could be a fan or possibly the color wheel. Once the tv gets going the noise quiets down a little, but you can still hear a slight humming or buzzing noise while the tv is on. The picture is also starting to fade a little while the tv is on and then it will go in and out of normal brightness every so often.
When I turn the tv off after a while it continues to make the slight humming or buzzing noise for a few minutes then completely shuts off.
The tv has a quick restart feature which allows the fans to run a little while after the tv is turned off. This allows you to turn the tv back on right away if desired without restarting all the fans. When I turn the quick restart feature off I do not hear any humming or buzzing noise when I turn the tv off.
Could my problem be solved by installing a new lamp or is it more likely a fan or the color wheel?
If it is a fan or color wheel problem (any suggestion as to which is greatly appreciated) approximately what are the repair costs for those issues?
Any help is appreciated.
