I brought a TOTAN out of storage where it has been for probably seven years. It is in generally excellent shape and has been running well through an LED upgrade, which obviously takes a good amount of time, and has seen several games played on it since then. Before the LED upgrade I replaced the RAM with a lockwhenlit NVRAM upgrade to get rid of the batteries -- I have done that on probably 15 machines to date and this one went just as smooth as all of the others. I also have been making sure the latest ROMs are installed in all of the machines I have been bringing back online but I do not remember if this one needed an update but I have been getting them from Action Pinball instead of burning my own. Just now, however, after it has been on for a bit the screen starts to get "static" running across it which escalates quickly and then the sound starts to pop and not long after that the game becomes unresponsive. Has anyone run into this before? I am pretty good at high level service but I have never gotten too deep into the hardware to really understand where to even begin to track this one down. It might be time for a service tech on this one but I thought I would post it here to see if someone knows exactly where to look for the source of the problem. Here is a video of what is going on:

If I power the machine down and leave it sit for a while I can rise and repeat from a fully working machine at power up to what is described above and shown in the video.

The test points seem stable and valid. The machine is plugged into a 20A circuit dedicated to four machines (none of the others are on) so I know that is not the problem. Today the machine is not even playable. It basically goes south immediately on power up. Going to call in a tech for this one. I will post the results here.

Went through all of the cables again and reseated them. Line voltage is nominal. Called service but with the summer schedule it might be a couple of weeks before I get to the bottom of this.

It took a while before getting the cpu board into the shop but the answer turned out to be at least explainable. The board needed rework right under the left corner of the battery holder where some of the reset circuitry is. Though the machine was in storage without the batteries installed old corrosion did enough damage here to make this machine die not long after being powered on.
