Model: Super Contra
Symptom: Dead. Garbage on screen. No sync.

Replaced 2 dead Fujitsu 74LS74 ICs that had no output. Replaced 3 dead Fujitsu 74LS153 ICs that had dead outputs. Replaced a shorted 7407 buffering the sync output. Replaced a bad custom IC as the Sync output pin was shorted. Board attempted to boot but would fail. Still had garbage on screen, but now had sync.  Replaced 2 corroded program ROM sockets and cleaned the corroded ROM pins. Board would boot but was stuck in a loop with repeating garbage patterns like it was failing a self test. Tested the 4 16-bit Mask ROMs - 3 were bad. Replaced the 3 Mask ROMs and the board booted to a corrupt, but readable screen with multiple self test failures. Replaced a bad Fujitsu 74LS153 with chattering outputs and a bad 2018 SRAM. Board would boot but had corrupt backgrounds, no sprites, and no sound. Replaced corroded sound ROM and its socket. Board now had sound. Replaced the other 3 graphics processing customs and the board now had backgrounds but corrupt sprites. Replaced the last Mask ROM with an EPROM to fix the remaining issues and tested the PCB.

The last Mask ROM replaced checksummed properly in the EPROM programmer, but would not operate at speed.
