I recently had the white dot issue.. purchased a new DMD, replaced it.. all seemed ok...

But now, i am noticing vertical bands in the image when i'm on various sources.. xbox, ps4 etc.. but not all the time.. seems to be hit or miss..

They are faint.. hard to see, but they repeat in a patter across the screen (black in color and banded)..

Has anyone experienced this?

Screen no longer coming on.

So I have had my Samsung LED DLP just sitting in a spare room for awhile now in hopes some day to be able to repair it. Before the current issue I had successfully replaced the DMD chip and it worked great for about another 8 months. The issue I am running into now is that the screen will no longer come on. This is what I have done and noticed so far. I plug it in, and hear a click as if it recognizes the power, the fans come on. It has a red led on in the bottom right corner. I press the power button and the screen acts as if it wants to try to come on, like the back light or whatever is trying. The green led blink 4 times and then the screen goes completely blank, leds are blank, but the fans are still going. I get no menu items or volume menu or anything during those 4 led blinks. Any one have an idea what this could be?

You might try looking at the Sub Led Power board.
It is mounted on the right side looking from back.
It will have 4 or 5 capacitors in a row that will leak black stuff or get puffed up
(slight dome) on top.
