yeah its odd - lots of uknowns at this point. Here is the history of it so far:
So I purchased this monitor about a year ago as a "maybe" works type thing. I have a main WG monitor, but its not as close to spec/original as this one - so Id prefer to use this one. When I purchased it, it worked - although the lower horizontal 1/4 of the screen was dimmer than the upper 3/4. Both me and the seller figured it was a cap issue. Sent the chassis off to CRT labs - who recapped and verified it worked on his test bench. Got it back, very well packed and shipped - so no reason to suspect damage - but it has sat for the last 6 months waiting to go into my astro city (being restored).
So Saturday night, a group of us from this forum had a get together and decided lets at least test it, plugged it all up with no PCB or anything - just to see what it would do.
Hooked it up to a freshly recapped capped power supply and fire it up:
1. no picture at all, get static building on tube, and very high pitched whine coming from the yoke.
2. Monitor cuts off after about 4-5 seconds
Test 2:
We unhooked which I assume is the 2 horizontal plugs from the chassis that go up to the yoke:
1. We get a nice bright white line (2-3cm wide) running vertical down the center of the tube, no yoke whine, and its stable like this until we power off.
Test 3:
We unhook those "working" 2 plugs and then hook back up just the (assumed) 2 horizontal wires and power up.
1. Same results from initial power up.
Thats as far as I have gotten.
(we also switched out 2 different power supplies just to rule out that - with same results.)
Assuming I'm not doing damage to the tube by these tests - I can take a better longer video tonight and post.
