Sometimes when you come across a game you haven’t seen in a while another one isn’t far behind.
I get a call for a Data East Teenage Mutant Ninja Turtles that won’t keep its settings. I try to help someone over the phone first in case the problem is easily corrected before charging someone for a service call. This also gives me a better idea of what the problem is so I can bring as much as possible to fix it without a return trip.
In this case a fresh set of batteries didn’t fix it. There was corrosion inside the battery holder that fortunately didn’t go any further and damage the board. I put in a new battery board, part number 27905504, reheated the pins and he’s back in business.
The only other issue with this exceptionally clean Turtles was the G.I. Connector on the power supply. The pins were burned, but not so bad that it required changing the pins on the power supply.
During a service call I always recommend an LED upgrade and a color DMD where applicable. These upgrades eliminate a lot of future problems such as failure of the high voltage section of the power supply. Also as these high voltage glass displays age they are getting weak and failing. A color DMD eliminates both problems.
My customer ordered the parts and as soon as they arrive I’ll be back to install everything. You can see part 2 here.
