Question about Samsung DLP HL-P4663W 46" Rear Projection HDTV-Ready Television

1 Answer

Hi, I have a Samsung HLP 4663W TV and cannot get it to power on. We bought it used about 4 months ago, but has been fine.  Did not notice any problem when we shut it off, after a couple of hours would not turn on, timer light blinks when tried, sometimes lamp lights up and sometime the standby one.  I have it unplugged to try cleaning it first, I was reading how and then lost it, started telling me how to get to the fan to blow the dust out, can you advise, Thanks.

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 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.

If you have already replaced the lamp and ballast, to no avail, then it is time to take it in to a certified repair center.  Most will charge a nominal diagnostic fee.  My 61" did the same thing and it turned out to be the Light Engine (of which the DMD Board is a part).
If the problem were the color wheel, the lamp would come on for a bit until the color wheel sync couldn't be achieved and then it would turn off.  The all-3-flashing-lights problem is the lamp.  Here is a page from the service manual on the 3 blinking lights problem.  
The Light Engine controls the ballast via a separate signal than the 320 Volts.  The voltage reading means that the Power Board is working properly.

I have a samsung hlp 4663w dlp tv...it just stopped responding to either the remote or direct attempts to turn the picture on...the tuner/amp is working fine as we still have audio, just no video...there...


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

its the problem in the circuit board so resolder convergence ic's. if that does not work, change (STK-xxxx). they are located on the main power supply board.

also check for any blowned fuses on the board.
