WG 6100 - no horizontal deflection after full B.R. rebuild

I have a k6100 that was working but had some issues so I did the full deluxe Bob Roberts kit on the thing to shotgun it. Now there's no horizontal deflection at all but appears to work otherwise.

So....what is the most likely thing that I screwed up? One of the chassis mounted transistors? Perhaps I grounded one out somehow? One thing I did notice was that a couple of the screws had some heat-sink compound on them. Could it be that I didn't clean them well enough and one of them isn't making sufficient contact? Would that cause this?

What's the recommended way to track this down? Thanks guys!
 
2nd day update...the spot-killer light is lit but I'm still seeing the vertical. And I can see movement. I'm including a link to a short video so you can see what I mean. The camera made it look much brighter than what it really is....don't worry, I'm not burning the screen. Here's what all was replaced as part of Bob Roberts kit:

R106, R701, R903, R901, R907, R910, R911, R926, C800, C803, C100-C103, D100-D103, C910, C909, C905, C914, C901, C902, ZD902, Q901, Q902

All 6 frame mounted transistors,

C503 on neck board

A few other components were replaced on the deflection board by the LV2000 but that was actually in place previously. The monitor was working before I did the kit but it had some issues with intermittent partial deflection for a while so I did this kit to try to fix it. Now I just get this. Oh yeah, here's the link to the video:

Not sure if anyone even read this but just for the record it's fixed now. The fuse at F700 was bad. Not blown though. It was faulty. When I pulled it to check, it read fine. But if I rotated it 180 degrees it would check bad. Rotating again caused it to check good. Loose filament inside apparently.

Anyway, it looks great now.
 
Hehe, congrats on the fix dude. Had similar issues myself on a Tempest 6100, same as you did the Bob rebuild kit, new lopt and installed LV2000. Again was working before I installed the kit but was a bit flaky, then no deflection at all afterwards.

Turned out to be bad connections on the chassis transistor sockets.

Wouldn't have helped in your circumstances but for search future ref ;)
