Hello, I recently purchased a data/east secret service.
I'm just a beginner and I need your help.
I checked on the tp and 5v are missing. I replaced the transistor TR5 (2N6057), but nothing ...
please help me to fix it.

What's the problem that you are having with the game?
)
Quoted from torpedo:the cpu will not start because missing 5v.
Did you check the connections on the Cpu?Did you check the fuses?Problem could be on the power supply board.
My brother in law had a power issue on that exact same game. Some clever googling pointed to a specific transistor the board. In the end, he decided to just replace the board for $80. After searching, it appeared that a lot of folks had multiple issues with the power on that game.
Sounds like he's missing the 5V before it even leaves the power board to the CPU....
Do you have 12V at TP3 or TP4? That will tell us really where to look.
If you don't have 12V either, then:
Check F1 and F2, the fuses to the bridge rectifier for the 12V/5V circuits.
Check for AC voltage on those fuses to make sure you're getting power from the transformer.
If you have AC voltages, then check the DC +/- at the Bridge Rectifier.
Any signs of burnt connectors on the Power supply board?The issues with Data East majority of times is Fuse holders that fatigue and burnt connectors.Try reseating the large square connector on the power supply.Check the header pins for any signs of cold solder joints.Cap C2 (100mfd 25v) as this likes to fail too, and can shut down the game

Thank you for posting this.
It saved the day on my Time Machine...party tomorrow - Volunteer Appreciation party for Pin-a-Go-Go, so thanks for the lifesaver-post!

Quoted from stangbat:Always replace C2.
I think this will be my new motto.
Quoted from pinballnut:Thank you for posting this.
Glad it helped. Always replace C2!
