Will continue getting more white dots as tv life go on.This tv still under warenty?Yes,talk to Samsung right away,this problems most likely a design flaw IC they put in the tv for it Light Engine block.The light engine block projection system it is a brain of the tv for a DLP tv.The only repair for this is to replace the whole Light Engine block system,not possible because the cost would be the same or almost the same a new tv itself.Out of warrenty tried tv shops,for a used and rebuild light projection engine if want to safe this tv.
The most common failure on this set to cause that symptom is the power supply. There are capacitors that fail and you can usually see most of the bad parts just by looking at them. If this is the case the best way to repair the problem is to rebuild the power supply rather than replacing it. Mainly because another power supply will have the same problem down the line but you can rebuild your board with heavy duty replacement parts for far less and have it last longer. Most shops will charge about 125-250 us dollars to do this repair. To do it yourself you need test equipment and soldering supplies. Better to have a repairman do this one. Good Luck, Russmann.
Unfortunely the optics engine is faulty, one of the small LCD inside the light engine is coming apart. The only fix for this problem is to replace the optics engine, most call it Light Engine. You can get one fairely cheap from this site. COM">WWW.TRISTATEMODULE>COM . They sell optics engines new or rebuilded ones.. They will even repair yours..
You have a defective light engine and you do not have to be under warranty for Hitachi to replace this part. We just went through this and here's what you need to do. Call Hitachi's customer relations department at 800-654-7013 and tell them that you have a defective light engine. They will act like they've never heard of this problem but they have. They will give you the names of some certified dealers in your area to call. Once a tech comes out and confirms that it's the light engine, call Hitachi back and they will send a brand new light engine to the dealer and Hitachi will cover the cost of the part (cost $1500).
Here is the deal, if you're under warranty, Hitachi will cover the part and the install. If you're not under warranty, all you pay is the install. Our install cost $400. Others on this site have paid $200. Do not let anyone tell you that you have to pay for the light engine part...you do not. Hitachi has not recalled this part but they are replacing it for free. Also, deal only with Hitachi customer realations number that I listed. Good Luck!
