Question about Hitachi 55HDS69 55 in. Plasma Television
For several months now, our Hitachi plasma tv has little green dots over most of the screen. They flicker, almost like tv snow, and are more noticeable on a darker screen image. In some instances they are not noticeable and sometimes they affect how well you view a show. What in the world could be wrong? THanks in advance for any solutions.
I know I a few years late, but for the benefit of others I'll share my experience. I have a Hitachi 42EDT41 and it had lots of green snow-like static dots - mostly over black areas of the screen. Other forum posts suggested adjusting the VSCAN on the Y-Sustain board (upper left corner when viewed from the back w/back panel/cover off), but my Hitachi had not VSCAN knob to adjust. That's when I read this post which informed me that what I was looking for was the VR1 or VR2 knob on the Y-Sustain board. I slowly adjusted the VR1 (counter-clockwise) as suggested. The green dots diminished but still remained in one small area. I, then, rotated the VR1 knob back to where I marked it and lo-and-behold the green dots were gone. My thanks to pleasefixitDave for the post. I saved a lot of $ and it was super easy :)

That is called diffusion. that can be adjusted out in most cases by adjusting the y sustain pcb but can also be the main pcb, the logic pcb and panel itself but not likely.
