Question about Samsung HLP4663W 46" Rear Projection HDTV

1 Answer

Samsung hlp 4663w picture is all horizontal lines

After the set is on for about 15 minutes it gets all horizontal lines and colors across the whole screen. Sometimes it just corrects itself if I leave it on for a few minutes. I also noticed when it is doing that and I turn the source off, it goes to a blue screen but still has like remnants of the previous picture even with the source off. It almost seems like the "processor" gets too slow or stuck. Any ideas? Any replacement part suggestions

We have a samsung DLP tv model number HLP 4663W tv. The picture went so we replaced the bulb. Still no picture and the tv makes a noise that sounds like a fan and the tv cycles on and off by itself. ...

Yes, almost certainly a bad color wheel, see attached photo.

If you remove the lamp and look in the direction it faces you should be able to see the wheel, look for it to be missing pieces or shattered.

You Tube has detailed video instructions for replacement in most of the Samsung sets; I have replaced dozens of the wheels.

If the capacitor on the ballast was puffed up or blown up you have to replace the lamp, ballast & SMPS at the same time. But if the ballast is not trying to fire the lamp it sounds like the color wheel is not coming up to speed. If this is the case, the set will not turn on.

I have a hlp 4663w that will not turn on checked the bulb it good. three lights blink that it .what is the prob

First. Lamps can look ok in the center and still be bad. Install a new lamp since I do not know when you replaced the lamp or if at all. Turn on the set and at the same time look through the Lamp Door vent slots to see if the lamp Illuminates. If so your lamp is ok and the Color Wheel is bad.

Replaced lamp & color wheel, no picture

Check your old lamp. Do you remember what its condition was like. If the tube inside the lamp was shattered into a thousand pieces that is a sign of ballast problems and that is where you should start to look. After all the ballast is what runs your lamp.
