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

1 Answer

I have the same problem. I am up to 6 spots in one week. I called samsung and they were useless. The cost of repair is over $900.00. I told the rep. that many people are having the same problem. He answered that I couldn't believe everything I read on the net. Please everyone with this problem, call Samsung. I am sure they know it is a major flaw in their TVs but they refuse to take action.

Same problem for me ... check out this thread on AVSforums about it.

I have the same exact tv as you and had the same problem. I took it to a repair shop who told me I needed a new DMD chip and that it would be 850 to fix. I used the information in thread above to get the part number and bought the chip on ebay for under 200. Here is a link to the listing CHIP

People have had good success. I will be replacing mine tomorrow.

**UPDATE**I received the part last Wednesday and it took me about 45 minutes on Saturday to fix it. No more spots and the tv is working fine so far.

I have a 65hm117 tv. It has white spots and every day more spots ap[pier. What part do I need to replace.


I have the same problem with my 65HM117. Funny, but it started just when I was getting a FREE repair for a Samsung LCD tv with bad caps on the power supply about the same age as the 117. The problem according to Samsung tech (who was kind enough to look at it while he was here) is the DMD (digital mirror device) chip, the "processing" part of the DLP (Digital light processing). Suggested I call Toshiba. Toshiba rep, obviously not in the USA, told me Toshiba doesn't make DLP's anymore "because of all the problems." They apologized repeatedly, repeatedly pointed out the unit is "out of warranty," but NO help or recal even though they know they built a product with defective, unreliable technologyl. Bottom line, Toshiba lost a customer but SAMSUNG has one for life! I'd repair it, but can't find the part number for the board with the DMD...

Small white spots appearing on T.V. screen.


The DLP chip is failing and will have to be replaced. Samsung is covering the cost of repair for this problem on SOME models. You can call 1-800-samsung to find out if your unit is covered or to find the nearest service center.

Numerous white spots on Smasung DLP TV


You will actually get white and black dots , the black ones are tougher to see because of the color in the background , within 2 months youre picture will be fully covered with dots....I went through the Samsung website troubleshooting flow chart , and it led me to a bad Digital Micromiror Device , or DMD board . What is actually the problem is the DMV chip connected to this board . Inside this chip are 3 million tiny mirrors ,and when they physically get stuck , they either show black or white instead of a color . Samsung will not tell me the part number of the chip , they will only offer to send a service tech to my house .

Hitachi 50v710 Yellow spot


I found out that Hitachi has a class action law suit against them for the light engine problem. I called them and asked what they were going to do for my tv which is out of warrenty. The reply was that they would pay for new light engine. I said what about labor. No they would not pay for labor. I asked to speak to supervisor. I was told by supervisor that the tv had to be inspected by certified repair person. Cost for this was $125 but would be applied towards the total labor cost. Repair guy came to house walked in and said he did not even have to turn tv on to know the problem. We called Hitachi to set up shipment of part. Hitachi told me at that point that they would cover all labor costs also. Part has been installed this week and tv is like brand new set.

Good Day;

It sounds like the DLP may have a bad light engine (optical block), if so call the factory's customer service rep and ask for a concession, it is a very costly repair and they will normally cover. Call a factory authorized service dealer to confirm your concern.

Good Luck, big irish.

Spots spots spots!!!! Everywhere


It sounds like it could be either an issue with the video processing in the unit or an issue with the light engine in the unit.
