From Raster No Vid To Vertical Collapse: All In A Day's Reflow

This K7000 came in a Z-Back I picked up last week, When I fired it up I had Raster with no image. I read some threads here and reflowed the chassis and neck board. When I fired it up post reflow I get what I am guessing is vertical collapse.

Clearly this is something that I did reflowing (yay me). I noticed the wires that go to the remote board had some jumpers. I am guessing I should verify their continuity, but not sure if that would cause this.

Any suggestions on what areas should I check first? Could I have killed the IC just by reflowing?

I think I got it, the bottom two legs of the IC were "wiggly" with lifted traces and inconsistent continuity. Going to try a jumper and see if that fixes this, if not will replace IC.

Hahahaha I fixed it, but then I broke it again. I made the jumpers which appeared to have solved the collapse, but I broke a clip in the flyback so now that has to be replaced.

Oh man, I really thought I might have had a working monitor that I didn't have to dump $50 in parts into. I guess it's still better than no monitor at all.

I think that's the worst feeling ever! I did that a while back, rebuilt a k7000 found a failed resistor and dropped it in a cab to test it. Picture looked great and I was pleased with my work. Feeling good I grabbed the remote board to tune in the picture and heard ZAP! I didn't secure the chassis in the frame and it slid forward and grounded out :| Luckily it was only the fuse and one resistor that burned, so it's back running now - but man the roller coaster of emotion!

100%, it's like yay I fixed it and it didn't cost me anything, but time and then...well, time to place a $50 parts order.
