Optimus STAV-3260 Digital Synthesized A/V Surround
Could be several causes. Bad connection near the stand-by power transformer or the transformer itself could be open. The main Micro could be bad. This is a job best left to a servicer. Optimus was sold only by Radio Shack, they still do repairs.
There is a problem in the audio output circuit. Most likely the output IC(S) went bad. This is a solid state unit and there are no user replaceable parts inside them, Please take this unit into a pro to be diagnoised. Good Luck
How to hook Optimus stav 3770 to tv
well mixing old AVR with newer TV (non told) or the reverse
early AVR (mines packed in box attic) has no digital ports
only has RCA analog and no hdmi ports. (retired it ,just like me)
see there, that is progress. (1/2 joking)
just looked at 3770 is all analog a sea of white/red/yellow RCA jacks on the rear.. OLD tech.
no TV told but the the best TVs like LG and SAMSUNGS have both.
analog and HDMI digital jacks.
mine does. LG55xxxxxx
there are only 3 choices
new AVR, (best choice with a future)
buy older TV (hah)
buy LG with both on the rear.
D = digital
A = analog RCA pin jack inputs. video and audio too.
a far better TV has both not just HDMI.
