Hi all, working on a Double Sizzling 7's game. A few notes before I go into the trouble:
1.) 502 Board
2.) No damage from Varta, removed before it started causing any damage, also U79 removed, board worked 100% in another machine with DoubleDiamondDeluxe game chip on it
3.) Known good PSU installed (swapped in)
4.) No door closure issues, cash door bypassed.
Problems
- I can't set a Machine Serial # or AFT Asset # - I need to set these in order to get TITO working. I can set ALL of the other options on the machine using the deck buttons but when I go into Machine Serial# or I go into AFT Asset number, it will no longer exit (save) the menu, nor will it allow me to set anything. I can move down the number line (underscore) but can't set anything nor exit the menu - I have to turn off the machine to get out of that menu area. Very strange. I ordered a replacement I/O board for the door I/O - it's a strange one - 14940201W (my others were all different) Just to make sure that isn't the fix.
- Printer is being seen as "printer 2" and won't print tickets while playing. Never seen the printer as being found as Printer2. Printer is "enabled" under options and even the I/O test prints DEMO tickets without issue, but when you try and cash out it says "sorry printer is not available" I made sure to try the "Discover NetPlex devices" under the Options menu for printers. It found it - as Printer2
Just an added detail - Machine originally had a 1270 MPU in it but the 1270 wouldn't Clear (1 flashing Amber LED on clear chip) and no amber LED's on KEY chip_. SO I decided since there is no optional sound on this one game rom to swap to a 502 (MPU & Motherboard) and the serial# and AFT # problem carried over, even after the MPU & Backplane swap. New setup after transferring boards involved a clear & key so everything was setup again from scratch, using instructions from here.
Chip on the board is SB101030 and RB says it's the right chip for the 3-Coin, 1-Line, 3-Reel machine.
