I have a VS super mario that had a badly distorted picture but coined up great and you could here it play. I tried to adjust the monitor with no luck so I figured maybe it was the board. So I got a new board put it in and now I have no picture at all. I put the old board back in and still no picture. Both boards credit up and play blind. When you turn the game on you can here the HV come on. Has anyone here ever had this kind of problem? Does anyone know what to do or to check?? I dont know if this is a monitor problem or something else.Thanks
 
Hmm sounds like a monitor problem to me. Did you check all the fuses on the chassis ( board under the monitor)? Check for loose connections?
 
Did you try turning up the screen brightness? there are 3 knobs for it. One on the flyback, one in the bank of 5 pots (it's next to the volume) and one that sits in the chassis. Mod will post a diagram if you can't find it.
 
What gets me is the fact that it had a picture(although distorted) and now nothing but you can hear the flyback power up.
