monitor woes...with WG 460x series and 4900 and G07

[GMZombie]

Im currently trying to fix about 5 monitor chassis's that i have. i have 2 WG 460x series 1 wg 4900 series and a few go7 models too and all of them dont work for one reason or another. It really is making me mad cause i want my games to work but have to fix all these monitors to get them to work and dont know where to start. Ok im off track first off my WG 4601 series i have replaced the caps in it and this is the problem. I can see no image. I had an image before a few weeks ago when all of a sudden the monitor would act as the tube was filling up with water and the screen would go up to the left side of teh screen(vertical mounted). eventially there was no screen and that was it. at the time i thought ok a cap kit might fix this...so i went and bought cap kits for the wells chassis's and installed them. well the monitor still f'ed up and the other chassis the 4606 will not turn on with the original horizontal/vertical card it has to use the one from the 4601 and then it starts up. but it has the same effect as the other chassis so i think that it is the H/V card. Anyone else have problems like this? Anyways my go7 chassis's 1 will turn on but you dont see anything but you can hear it. the second one dosent even turn on. And the wells 4900 chassis i have a cap kit for it when it is turned on it displays red lines across the screen. like a bad ground would show on a game. eventially the lines will go to one line. So i think the cap kit i have for it might work on that. Anybody have any ideas?

I can see no image.

On the 4600 series monitors you will install a brand new trimpot on the video interface board. Nearly 99% of the time you will need to adjust it to see a picture after doing the capkit. It will need adjusting again after 3 days of constant 'on' use to age the capacitors and the control will drift.

Capkit both those monitors first. If after capkitting you still have problems with the one that turns on but no picture try readjusting the 'screen' control on the flyback.  On the one that doesn't turn on it could be one (or both) of two things: bad B+ regulator transistor (2SC1106) on the left side under the giant white ceramic resistor and/or the horizontal output transistor shorted and blew the little soldered-in fuse. Could even have a bad flyback.

And the wells 4900 chassis i have a cap kit for it when it is turned on it displays red lines across the screen. like a bad ground would show on a game. eventially the lines will go to one line.

Sounds like an internal short in the picture tube that a rejuvenator may help/cure.
