No, I didn’t. But I suspect that there might be some unwanted bridge somewhere which is directing electricity where is shouldn’t and lowering the overall voltage in that part of the circuit.
I had no time yet, but I was thinking to remove the components of that part of the circuit and solder them onto an external board one by one. If I reach a point where the circuit starts working, I should then see if the last component moved was shorted with another one.
It will take a while, but I’d like to keep searching for the answer until it’s found :)
I would recommend to pay a visit to Wipeout Phantom Edition.
It’s an enhanced PC port that uses the original assets from the Playstation CD and I had a lot of fun with it on my deck a few months ago…
