Subject: [TechAssist] Panasonic PVM2058 dead
Have in shop a Panasonic PVM2058 that is dead. I need schematics to
trouble shoot the power supply. I have changed the Q505 and Q541. The
VCR P.S. section seems to be okay. But there is no led indicators no
mechanical movement nothing. If anyone has a pdf of this set I'd really
appreciate it.
Thanks Bill G.
