I picked up a used G70 with 1000+ hours on it. It seems to run OK, and I am able to get the focus & registration nicely done.
However, there is a LOT of video noise introduced into the signal when I playback a source. There horiz. lines running through the image (most visible on brighter backgrounds). These lines are spaced about 3/4" apart on the screen and oscillate up/down. Edges are practically non-existent because there is so much noise that edges just look like a line of spikes.
I have checked and re-seated every board on the unit I could get my hands on. No difference. I have tried S-video in directly, 480p, 600p, component in directly, etc., no difference.
The CRTs themselves appears fine. Internal test patterns render very crisp/sharp edges without noise, but as soon as a signal is applied it's crap.
My equipment is a Faroudja 2200, Sony 7700 DVD, Powerwedge power filters, and of course, the G70.
Prior to the G70 I had a D50 and the image was spotlessly clean. I can see the potential of the G70 (tighter beam, mag focus) etc, but quite frankly, the noisy image is ruining the show.
Any ideas, comments before I send the unit back to the seller?
PS. I have a IFB-12 from my D50 that I tried to get to work in the G70. No luck. The G70 sees it and the IFP-12 reports itself as active (red light on), but I cannot get an image through the IFB-12 to display on the G70. The IFB-12 is supposed to be compatible with the G70 isn't it?
Thanks, Karl
