Hi I have a Samsung HLN467W, a 46" DLP TV. And after 50-60 minutes, it starts to flicker white, like lightning flashes. But the whole screen is not blank white, it's more like the images are...


Hi,
It seems color wheel problem in your tv that gets problem after some time and you hear high pitch noise along with picture flicker.
Color wheel need to be replaced to solve this issue. Required color wheel is available with PartStore.com (click to view image of part and price info) and it is job of qualified tv repairman because light engine will take apart for that.
Hope these info will help you.
Thanks.

Samsung HLN5065W 50 in. Rear Projection HDTV-Ready


With the back off of the set it will shut off. There is a lever it engages to prevent the set being operated with the back off.

The color Wheel will cause a fan like or high pitched grinding noise. I can tell you where to buy it and also there are on the internet places with written and VIDEO instructions for the replacement in most of these sets.

Put the back on and see if the set again works and still has the noise.

Our tv made a loud high pitched noise for a few weeks and then the color went green to then shutting off. Now, when we try to turn on the tv, the light blinks and then it just shuts off and keeps repeating...


Hi, Symptom shows high pitch sound is of color wheel that is not spinning any more so TV stay in protection mode and does not power up. TV requires color wheel replacement.

TV making high pitch sound


Hi, There are usually 1 or 2 fans inside the TV's. Could be worn bearings, or fan blade interference. Sorry, without my electric ear working, I can only guess.

Phillips 54 inch rear projection,no picture.


One thing that comes to mind when you say high pitched sound is the HOT ( Horizontal Output Transistor). You may be able to find one at fry's electronics. They are pretty cheap. If you are handy and know something about electronics you may be able to replace it. I am not a TV tech, I have a background in electronics and like to play with them from time to time. Not sure this will help but good luck
