Question about Samsung Projection Televisions
I have a samsung dlp tv hl-r5078w and all of a sudden I've noticed these white horizontal lines that keep moving from the bottom of the screen to the top. I can see it especially when the picture is black. What can I do for this?

The unit has a defective light tunnel contained within the light engine. This part is not easily replaced and you will a qualified tech to replace it. Many service centers condemn the light engine at a much hight cost. Do not buy or let someone tell you the light engine must be replaced. This repair requires only the light tunnel.

Since I cannot troubleshoot the set I do know that the Analog bd or the Digital bd or both are bad. Since you had a power outage I really suggest replaceing both parts. You can purchase both parts and install one part at a time until you fix the problem if you feel confident enough to do it your self. If you use one part only then return the unsed part for a refund. Other wise you need a trained Samsung tech to test both parts. There are two Digital bds for this model. Digital bd part#s are BP94-01859F AND BP94-02084A. The Analog bd is a BP94-02049E. The only to tell which Digital bd you have is to remove the rear cover and look at the big shiny silver bd on the left side of the set on the bottom. You might have to remove both the Digital and Analog bd in the metal cage they are in to get the part number. But look for the number on the front of the Digital bd first before removing.

It seems you might have an issue with the dmd board. Go to the menu, and if the dots still show on the menu, the issue definitely is with the dmd board but if they don't come up on the menu, the issue will be with the video board.
