ALS Marketing Pentranic 1425 med res. I had vertical foldover on this monitor and after I built my own cap kit and installed it the vertical foldover was gone but I have a very slight jetter in the picture. I could probably live with it but it would be nice to fix.
Thanks Steve

 :) Thanks for the advice Rick. I pulled C318, checked it and it read 2.138mf which seemed ok to me. After inspecting the chasis again I noticed a cracked solder joint on T501, which I resoldered, and a foreign object wedged between 2 legs of Q302 on the parts side. After reinstalling the chasis everything appears good with no jittering. I have it plugged in to make sure nothing else comes up. Will let you know if any problems have appeared on Monday.
Thanks Steve

Had machine in Warehouse ready to go, plugged it in to check it and no picture. Subtle clicking noise coming from monitor chasis. Pulled it and checked Hori Output Trans, seemed fine any ideas on what to check next?
Thanks Steve
