Universal Classic - Black Cat - No Power - Please Help

<< < (2/2)

NZSOMA:
Thank you for this.
I'll run through these tests and post my results soon.

UNIMAN:
I am no help at all.
Cannot recall one Universal Aussie machine ever repaired here on NLG. The 8600 board seems to be the issue. Some kind of encryption going on there.
Never have seen a manual either.

Years ago there were a few South Africa techs here who knew these machines.

Sorry I am no help.

UNIMAN:
I do notice in your picture of the coin acceptor the two black optics below are lit. In the US grey optics are used so not familiar with black optics but I believe they should only be lit if something is blocking them. Dirt maybe? Try cleaning with a dry Q-tip up inside the optics. Do not use alcohol as it can cause damage.
It could be those black optics stay lit but I doubt it.

The optics require 5vdc so this tells me the 5vdc is available for the mpu.

My thoughts on encryption is pure speculation.
