Question about Samsung HLP4663W 46" Rear Projection HDTV
I also have had a problme with the Samsung. When I turn the set on, the picture stays black, the sound comes on, and first the "lamp" light flashes on and off. This progresses to all three - "lamp, Standby, and Timer" flashing. I have tried to replace the lamp with no change. I then purchased a new ballst which also was easy to change out. I still have the same problem. I still don't feel that I am any closer to having a working TV. HELP!
Skippy is right, you should check the color wheel. There are only two moving parts in the set and the color wheel is one of them. If you listen closely to the TV you may hear a high pitched whirr or whine. If so, you've got a bad color wheel motor. If you are mechanically inclined, take the back off and remove the lamp vent. Take off the screws and cables holding the optical block tray and slide the tray out. The lamp points directly at the color wheel. There is a metal heat sink held in place by two silver screws over the compartment infront of the lamp. Using latex gloves, remove those and the whole color wheel assembly will come out. Of course this process isn't as simple as I've stated it but with some common sense you'll be fine. When replacing the wheel pay attention to the model number. Some of these sets use a bearing setup and others an air cushion one. Make sure you order the right part. If you do order the wrong one, not all is lost, you can (with a jumper) modify it to work. Make sure your gloves are clean and re-install the color wheel, and reverse your dismantle. Good luck!
