Title: Donkey Kong Video Question
Post by: markrvp on March 18, 2006, 02:46:01 pm
I am restoring a Donkey Kong cabinet.  I have a two-board set that I have fired up, but the video is really crappy.  Lots of vertical smearing.  I thought possibly it was the horizontal adjustment pot on the video board, but shorting a 10K ohm resistor across the legs didn't fix the problem.  I made a short video of the monitor that shows the problem.

Here is the video link:

If it won't open automatically in Windows Media Player, you can right-click on the link and choose:  SAVE TARGET AS to put in on your hard drive so that you can play it back.

I would really appreciate it if you guys could take a look and point me in the right direction.

Thanks,

Mark

Okay I fixed it.  The MB74LS123 chip at A3 had one pin that wasn't seated properly.

My wife was saying she told our 9-year-old son that she would stick a bar of soap in his mouth three times if he didn't stop saying naughty words.   :police: 

He decided discretion was the better part of valor and stopped saying bad words before he had to get his mouth washed out.   ;)
