|
|
Hello, I have a HLP4674W, that was given to me with this problem. It powers up, then after anywhere between 1 and 10 minutes, the picture (which is fine; not dim or distorted) goes out but the sound continues. I then hit the power button and the light will try to light once and the color wheel will repeatedly start to spin with a high pitched wine. If I unplug the set for 5 or so minutes and plug it back in, the picture will come on again but for a shorter time before going back out. all the fans run, though it seems like maybe an over heating problem. A bad heat sensor? The 3 lights on the front blink, and the lamp and ballast have been replaced. Are these symptoms of a bad DMB board? Any help would be appreciated. thanks. |

I would start with the color wheel if it is whining.....If the color wheel is not spinning at the rate it should, the set will shutdown.

i was wondering about that however when the picture is up it is perfect and it doesnt distort or anything as it goes out; just goes black. also it only whines when its powering up, not when its running. could that still be the wheel? |

If there is any whine coming from the set, it is the bearings in the wheel going bad. This wheel is notorious for bad bearings...... |
