Hermann D980

[russrace]

Hi everyone.
Does anyone here have experience on repairing the D980 datascope used on older mercedes vehicles. It was used in the early ninities. I am trying to repair one that does not power up.
Any info will be greatly appreciated.

Thank you.

Does no answer you question.

Will do, the main board and graphics card board soldering looked bad, so I have completely reworked both boards but still no luck. My 12v and 5v supplies are all there too.

Thanks for the reply
