Monitor takes a bit to warm up (20 seconds or so), and when I whack the side of the cab, the picture dies for a second. If I hit it hard enough or often enough, it dies completely. If I hit the cab while the monitor is dead, I'll get a line that looks like horizontal collapse intermittently. The picture looks good when it's on, doesn't seem to be bad caps or flyback.

Cap Kit? Full Rebuild? Check solder joints first?

Stop hitting the cab? Or get a bigger hammer? Hard to tell the better path based on current info.

this is certainly a case of cold solder. saw it on a 39" Neotec in Cruis'n Exotica... was my first experience of seeing what cold solder can do. lol the sound from the game had the picture looking like an old broke ass TV, and sometimes would shut off completely, and come back on.

the good news is, this is an easy fix.

get out the soldering iron and dig in. if you have questions, ask. but that's the only way you're gonna fix this one. lol
 
FYI I noticed this issue while leaning on the control panel during normal usage :p Hitting the cab just proved the issue was due to vibration :p

Took the chassis out tonight, whoooooole bunch of cracked joints. Whoever worked on this before was even more of an amateur than me. Tons of flux all over the board, just huge globs of solder, lots of 'igloos' and no 'fujis' :p. Also found a few components going to ground where the pads had burned off completely, so I jumped them together.

Seems really solid now. I gave the cab a few good shakes and I saw a tiny flicker, but I was whaling on the thing pretty hard. I think it's good to go for normal usage.
