Hi, I have a Samsung DLP TV and it is displaying lots of black dots on the screen. Some disappear after warming up, others stay around. This happens regardless of what video source I am using.


First, check the optics in front of the light bulb for dirt. This will require disassembling the lens section. There is a youtube video that is most helpful. If after you go through the cleaning process and the dots are still there., the DLP chip needs to be replaced. You can get the parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

Screen is blurred with horizontal lines when 1st turned on. Goes away after 15 mins. Also black cloud appears on screen....moves around then disappears after a few mins. What is going bad?


The fault should be with its supply voltage to video output section circuit. Check this voltage. Check the smoothing capacitor used there. The video output card stage, can be located at the back [neck] of the picture tube, will directly plugged on to it; and can be pulled back out gently. Take care. http://electronicshelponline.blogspot.com/ Check this link for more details. Pull up older posts.

It sounds that its main digital board has damaged. Video processor section has the fault. It has no repair at component level. Should be replaced as card basis.
