OK, I have a U5000. It used to work, it was really light on one side, so I decided to cap it.  After the cap kit, I hook it back up, and turn it on, and I get no picture.  There is a glow from in the neck of the glass.  No picture though, its complettey black, doesn't look like it turns on at all from the front.  What could it be.  I pulled the boards back off and checked my work, all the caps are i nthe right polarity and I don't see any places where solder joints touch that shouldn't.  Did I f' something up???   I'm pretty pissed right now.  Any help would be greatly appreciated.
