I'm bringing up a dragons lair cabinet and want to get video output so i can run diagnostics. The internals have been worked on before so I spent today figuring out how to wire power and figuring out what is original.
Picture of ntsc decoder board attached. I believe this is original. Should anything be connected to p204? There is replacement power supply so I do not see how this board gets power.
Also the monitor is a Zentih model, and I do not believe this is original.
I attached a scope to bnc input of the decoder board and not seeing anything.
So, I need some help testing the monitor, decoder board' and laser disc player. Any help geatly appreciated.
Also there is a board labeled sidam 11470. It has an edge connector and is spliced into some signals going to the main logic board. I don't know what this is. It is pictured here.
My main goal is to get video output so if i need another monitor or a dvd player to test i will do that. Thanks.
