Question about Toshiba 56MX195 56" SDTV

1 Answer

Fan noise? When the TV is turned on there is a continuous fan noise until 15 minutes after it?s turned off. Before this started happening the only fan noise I heard was when the TV was turned off and only for a few minutes.I hope it's not the color wheel making the noise.

Re: Fan noise?

Does it sound like grinding ball bearings? like a bad computer fan? Hate to break it to you but it is the color wheel(part of the light engine) $900 part about $350 labor, and if the tv is out of warranty your out of luck. (happened to me)

My Sony KDS-60A2000 is 41/2 years old. About 2 weeks ago I could not get the tv to power up. the green stand by light just kept blinking. I powered off, then powered up again and the tv started and and...

TV needs lamp replacement as existing lamp got weak or has been reached to end of its working life, please note that lamp is not dead or broken so that is why lamp lit is not lit at tv front.
Hope these info will help you.

When we shut off tv for the day the fan motor continues to run it does not turn off

the fan will continue to run after the power is shut down on a DLP television untill the set has cooled down . But it should shut off within a few minutes

Optoma RD50 TV which shuts down on #1 fan failure

This could be a variant of, or a newer (or older) version of the "DMD fan failure" message.

Symptoms I had are, I stop hearing a fan when the message is displayed.
Then the temp LED keeps flashing RED until I either try to turn the TV on again,
Or turn MAIN power off/on again. BUT it repeats when I try to turn the TV on.
The picture appears normal until this happens ( about 15 sec.)

The solution is to FORCE a normal shutdown by hitting the TV off button
before the message appears.
You should see the power LED flashing RED/GREEN (cool down) and then RED (standby).

Sporadic Hum on HLP4663W

I would guess that its the fan for the lamp, as the color wheel will power down as soon as the power is cut. the cooling fans will continue to run

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

Samsung DLP HLR5668W has mostly dark picture + grinding noise

Pix looks like a light pipe issue, inside the Light Engine. as far as the shutting down, could be a bad fan causing the grinding and when stopps the DMD turns the set off.
