Hey all,
I thought I'd start posting fixes for monitors that are "out of the norm".
Customer sent me a K7000 19in chassis. Hot shorted, and fuse blown, white knob flyback still installed. Original complaint: "No Picture".
Replaced the hot, and fuse, couldn't see anything else wrong. Powered it up and it worked, b+ was at 122.3.
Did the re-cap and reflow, put it back on the tube, and it's in shutdown. The VR was putting out 134v, which was having the xray protect turn on. When testing the VR in another chassis it tested fine. I was doing some further reflow, and noticed around the yoke connector was burned up. I noticed it before, but it worked fine so I thought it was just a high-hour chassis. Well, one of the pins fell out of the yoke connector when I was reflowing them, and then it turns out D18 wasn't barely connected to it's pad. The entire area was oxidized, so I removed D18, fiberglass pen'd the pad, D18 legs, and the yoke connector pad. Re-soldered everything back in, and whammo beautiful picture.
These K7000s really suffer from oxidized pads. Sometimes you just need to take it apart, clean the component legs, and pads, and re-solder it all back in.
Hope this helps someone possibly.
