Hi Guys,
I had just got myself a service manual and had been having some problems getting my Data 800 to sync up properly to my HTPC at 48HZ 1280 X 720. Like an idiot I transposed the position of the cards and wouldn't you know it....I was adjusting the wrong pots. Now I have a unstable picture that has way too much noise around the edges of the raster line test pattern. It gets increasingly worse the higher scan rate I use. I only have a partial service manual and what I do have is quite simplistic and doesn't seem to help my problem. What I need is some troubleshooting help from someone experienced with this unit. I have previously worked on E Homes and Sonys only. As I said before the symptoms include noticable wavy lines and vertical instability that gets worse as the scan rate increases. I think I have knocked some voltages way out. I am comfortable with a meter but do not have an extension card to access all test points. I'm hoping someone here has dealt with this and can point me in the right direction as to what some of the critical adjustments are. I would be happy to pay for some phone advice as well. This is P*****g me off as I want to get rest of it dialed in. Thanks in advance,
Mike
