Frogger horizontal lines on screen after moving game

I just picked up a Frogger machine that was working perfectly before hauling it. Now it has horizontal red and green lines when you power it up.

Where should I start looking for a cure? I am new to this an no expert but think I can handle it with a little help from the experts here.

Appears to be a G07CBO.

Thanks

My congo bongo did something similar to that when I had improper contact between the 2 boards. Probably from moving it around as well, now that I think about it.

I don't even know if frogger is 1 board or more.

I would be very careful and make sure I didn't get shocked to death, but try moving the main board around when the game is on and see if you see any change to the screen. If you do, it could be a little short that is happening.

I am by no means an expert, I have just had a similar issue with a sega game.
 
It is one big board with a small board on the back of the tube. I tried wiggling both and checking cables. I can't see anything obvious, bit I'm sure your right as it was fine before I moved it.
 
I think Tronguy was saying that it looks like a game board problem, not a chassis problem. Try wiggling the connector between the game board and the monitor chassis as well as the cable between the two game boards.

+1 to gameboard..
%100 gameboard dont touch the monitor :)
 
Thanks everyone. It appears to have been the main connector to the bottom board. Video is ok now (valuable lesson learned, video issues may not be video related).

Now I have an audio issue. After about 5 minutes of play, speaker let's out an obnoxious squelch and then sound quits. Eventually comes backmif machine is powered off for awhile and I reseat some cables, etc. I am gonna check all chips and cables first. Not sure if this is related to moving machine or been there all along (seller didn't mention it).
Thanks again!
