Game On
Banned
Help please from you lovely people I am treying to help my brother who has a Roadshow. He tells me that all of a sudden the game stopped working with no apparent symptoms. When I asked further he confirms the game does not even boot. no Displays etc. He lives in Chester so he sent me the MPU and driver board as I requested. I initially though it would be the usual driver board issues with the Capacitors and 5 volt regulator but no the power board is fine and works perfectly in a Flintshtones I currently have. i have the mpu on the bench connected to a computer PSU delivering a stable 5 & 12 volts. When I connect it All 3 LEDs illuminate and stay on. There is no apparent damage or burning on the board. I took a risk and one by one put the Processor, NVRAM, ASIC, Game Rom & Security Chip into my Flintstones board and all are fine and boot normally I have not connected the switch matrix connectors so I get the usual "Check Fuses 114 &115" on the DMD but everything else runs ok so I know all the important IC's are good . with all these IC's out of the board D20 &21 stay on if I put in the known good ASIS D19 comes on and stays on as well. Can any of you good people point me in the right directions as to why all the LEDs are permanently on I expect the bottom one D21 to be on as it is the 5 volts but I understand D19 is the Strobe and D20 the diagnostics why do they say on HELP!!
