There's 3 fans. 1 by the video board. 1 in the middle of the set infront of the heatsink and 1 behind the lamp. make sure all 3 fans are running and put your ears by them to check. if all of them are running the sound might be coming from your colorwheel. If it sounds like a loud whinning/humming or buzzing noise then more then likely its your colorwheel. Let me know what you find and please rate me. Thanks
We replaced our lamp in our HLR5067w model and when we turn the tv on, no color and the lamp and standby light blink and light up thent the tv turns off and then it wil turn back on again.
SOURCE: After 10 sec. after start up the tv starts to make
Sorry to say it but Fredy2 has no experience on this set or he would know it is the color wheel that gets noisey. Secondly the fans start immediately, but the color wheel lags behind when it gets a signal from the DMD board. This explains why the pause before it growls. The way to change the color wheel is to disconnect the power and remove rear cover. The assembly on the right is the light engine. Unscrew the two screws and disconnect the four plugs connecting it to other parts of the set. Careful not to strip the plastic threads on the large LVDS cable. Remove light engine and locate DMD board(large metal object).On top of it are the two connectors to the color wheel. One is a ribbon cable and the other is a three pin plug. Disconnect them and remove the two screws that hold the cover on where they go to. Then you will see the color wheel. You can replace the wheel without the housing if you want to save money, but the color wheel can't be repaired. It must be replaced. Most shops charge about 250-325 to do this repair. Good luck, Russmann.
