View Full Version : R-type repair where to start ?

4th September 2006, 06:38 PM
Hi , i looked at my recent haul and realized that there was an r-type in a box labelled as robocop .

I power on the board and it says ram/roms ok , then nothing happens . The only thing i have tried so far is removing one of the roms to see what reaction i got ( the game never got to the testing screen )

anyone have any ideas on what might be a likely culprit or where i should begin in terms of testing out various possibilities .

Only suggestion I have is reseating all the roms.
Those pcbs are full of custom chips.
