ASTRO CITY -5 volts problem
(1/1)
robotype:
hello I have 3 astro city power units that lost the -5 VDC (so I can't hear the sound on taito pcbs etc).
anybody knows about this common issue and how to fix it?
CheffoJeffo:
Output rectifier problem perhaps ? I haven't repaired a switcher yet, so this is a guess.
If you have a meter and can find the diodes on the output for the -5V, check them.
robotype:
thank you! fixed it! it was just a small transistor.
