I need some help from the Berzerk experts out there!!
Well, I went to turn on my Berzerk tonight and after beeping twice (during the start-up self-tests) it was completely silent. The screen just showed a bunch of scrambled garbage. According to the manual it states:
1. Check RAM CHIPS 1E and 2E
2. Check transistor Q2 and associated components/circuits
3. Defect in gating chips 2A, 3A and 6A
4. Check the jumper used for chip 1E in correct
Has this happened to anyone else? If so, what would you recommend?
For #4, the correct jumper is being used (W5). For #2, the transistor appears alright but....sometime in the past someone attempted to add a homemade battery backup for the highscore save and it looks like a sloppy job. Doesn't look like it is but could this be the cause?
If it's the chips as described in #1 & #3 then I'm in trouble; I have no knowledge about these components. How can I check the RAM chips in 1E & 2E? Or how can I check the gating chips?
Any help would be appreciated and thank's in advance!!
Take care,
