Peavey DPM4 - screen has power but no characters
I dug out my 1989 Peavey DPM4 from my crawl space. It turned on but static noise came out. I opened it up and noticed the leaking battery issue. I replaced the battery. It turns on and I see a little bit of light from display but no characters show up. I tried the global / midi + slider to adjust display but nothing.
Any suggestions?
