Title: Tetris cabinet - game plays, but no video. Any ideas?
Post by: edge on November 06, 2007, 05:41:53 pm
I picked up a Tetris cabinet locally for 75 bucks.  Supposedly, it was working until 2 weeks ago, but when it was moved into storage, the monitor dislodged and fell off its shelf.  Since then, it hasn't worked.

I am thinking that when the monitor fell, it pulled a wire or two.  Unfortunately, I couldn't find anything obviously wrong.  But with my limited skills, that's not surprising.  :-[

The cab powers up, I hear the monitor power up (ie hear static building up), and the game plays... but no video.

I have attached a bunch of pictures.  Hopefully someone sees something wrong.

Thanks for the help.

Can one of the mods please move this to the Monitor forum?  I think it would get more nibbles there.

Thanks.

This pic looks like the connector for the remote board that goes to the monitor.

Which if it is then it should be plugged into the monitor somewhere.
(I can't recall the K4901 setup off-hand)
But if you do find a spot, verify which way it goes first. (not backwards that is)


You may also need to pull the main chassis and check for breaks or bad solder joints since it got jolted pretty good.

Kevin - thanks for the suggestion.  Unfortunately, I could not find a place to plug that remote board connector into the monitor.  I did not see any pins that would accept that white connector.

We are going to pull out the monitor and relook at all the wires going into the monitor chassis. 

Keeping fingers crossed.

I can't quite tell for sure.... is there anything connected to the video input on the monitor?

Ok. I finally had some time to try out these suggestions.  Unfortunately, no luck.

Both video connections (as you pointed to in your pics) were secure and I was able to trace back to the jamma harness.

That white connector that was just hanging there... It connects to the remote monitor adjustment board on one end.... not hooked to anything on other end.  Problem is, I cannot find a place to plug in that white connector. There are no pins anywhere that match.
