Bob I have seen the DMD on the light engine cause this

The DMD board is available through your local parts distributor
You said you had sound so the analog board is working
The digital board may also be suspect
It is a lot more expensive than the DMD
I would replace the lamp if it is over two years old just on principle
Good luck

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.

Samsung hlp 4663w does not receive off air signal from roof antenna through antenna ports 1 or 2. Get cable signal just fine through same ports. Same antenna works fine on other tvs. Whats the problem and...


If you're in the US, you will no longer get antenna signals because the US has recently switched to digital. The TV you have does not have a digital tuner and you'll need to purchase a digital converter box that converts a band of analog signal to digital.
