Title: Need help with Golden Axe PCB weird text problem
Post by: action76 on April 08, 2018, 11:53:06 pm

Got a very clean Golden Axe board that I have de-suicided. Boots and plays fine but has some scrambled background issues and some weird problem with text that I have not seen anywhere on anything I have looked up. I cannot even go into test mode to troubleshoot because I cannot read anything. Anybody have any idea where to look or what to do to try and clear up the garbled text so I can troubleshoot further?
Thanks

A few easy things to try first:

- Check the board for any physical damage. Even the smallest scratch could mess things up for you

- Clean the Jamma edge connector

- pull the roms off, clean the legs, then re-seat them

- increase the voltage. sometimes these old boards just need a bit more juice to get them to play nice

- when running, try pushing down on some of the custom IC's and see if that changes anything.  Also check to see if anything feels hot to the touch. Might help narrow some problems down

These are the low-hanging fruit things you can try, before having to dive into the schematics and logic probe stuff.
