I finished up my first cap kit last night and now I don't get a picture. I just purchased the cab and the monitor worked but was very noisy,dim, and just looked terrible.

When I flip the power switch I can hear the initial "boosh" of the monitor turning on and the screen gets static but nothing shows on the screen. Almost immediately after there is a faint 'click'. I never get a picture and there is no neck glow. Any ideas?

I made a quick video of what's going on.

Double check your work. Either you created a soldier bridge or installed a cap backwards... or used the wrong value.
 
Ok thinking back and doing some research here at work, I think I may have a couple "lifted pads" on the board. I'll post pics when I get home. From what I'm reading you just scrape the board lightly to expose the copper and solder it to the hole?
 
Exposing traces can be tedious and they are often very fine, meaning they don't provide much to create a good solder joint. If exposing traces doesn't work, you can run a wire from the leg of the cap where the lifted pad is, to it's destination in the circuit.
 
Ok so I've taken pictures of the what I see are the problems,mostly removed pads. I've been reading all day about how to jumper a wire to another spot but I'm not sure where. Can I just solder it to another capacitor in the chain?


For this one do I do a jumper from the unpadded c233+ to the J209 in the chain?

Do I go from C960+ to C961+?

I have no idea for this one (C621+)

You have the right idea about the jumpers, just make sure to remove all solder around the area of lifted traces, and clean it really well, so you can see for sure where the traces lead to the next component in line.

Also, anytime you do work on a monitor, you should always verify/adjust your B+, to ensure it's set within range. On this particular monitor, I'm not sure what the setting is, so you'll have to do some research on that.
 
Dude no offense but that's some of the worst soldering I've ever seen, I can see some caps that are only half soldered in. Please recheck your work
