Hi all,
hoping somebody can help me out a little bit. I have recently picked up a set of 8 Tesla II cockpit simulators (Battletech Pods) from virtualworld entertainment. The pods were built in the 90s and then upgraded in the 00's.
The previous owners did not know what they were doing at all so I have been cleaning up some horrible repair work. The radar screens all need some love, so I started with the worst one.
It seems to be a 14k3002, although the label is somewhat damaged. It is a 14 inch CRT from Wells Gardner with a P583 neck board, P735 power supply board, P737 remote adjustment board, and P736 main/deflection board. The radar screens are mounted vertically in the pods.
The image was very narrow in game, so it was shrinking vertically from the monitors perspective. The image was also just generally terrible, blurry, distorted, colors were weird, etc. I couldn't find a suitable cap kit that I could get quickly and that would be complete, so I counted up and ordered every cap from mouser to replace EVERY electrolytic cap in all 8 radar screens. I went through and replaced every electrolytic in this particular monitor (about 40) and touched up some of the bad rework soldering that had been done on this board. I have a fair amount of experience in electronics manufacturing, so my soldering skills are pretty good.
After hooking it back up I carefully adjusted the monitor and ended up with a really crisp image with very good color balance, good hold and geometry etc..... but the vertical size, though improved is still leaving an inch+ of blank space at the top and bottom of the screen. The remote board Vsize adjustment effects the vertical size as expected, shrinking and expanding the image, but it is maxed out, and the image is still too small.... so I assumed that I needed to adjust the one on the main board... the weird part is that the Vsize2 pot on the chassis board has absolutely no noticeable effect at all. I do not locate a Vsize pot, just Vsize2. I see the label Vsize next to the remote board connection for the Vsize pot on the remote board, but there is no pot near there.
Monitors are definitely NOT my area of expertise in electronics. Any ideas would be greatly appreciated.
thanks,
