Hi,

I got a problem on Luxman AV Surround Sound AM/FM Receiver RV-357.
There was no Standby LED indicator shown when I powered up the set.
As a result of the above, I tried to investigate the root cause of it....

Below here were findings, checking physically on Power Board RV-357-9 :-

- Presence of Main AC Power Supply
- No blown fuse (Location F1, 3.15A)
- No blown ICP fuse (Location IC552, ICP-N-15)
- Presence of 6.0 VDC at pin 3 of voltage regulator 7806A (Location IC551), but there's still no presence of Standby LED indicator shown on the front panel. I could not progress anymore from here....

I would appreciate it if anyone of you could enlighten me.
Should you have RV-357 schematic, kindly share it with me.
Thanking you in advance.

:scratch1:

Hi,

I don't know if it could help you but I was facing to the same issue with my RV-357 and I found a switch located underframe named "SUB" and it was on 'Off' when I moved to 'ON' then my device started again.
I think I touched this switch during moving it.
Thanks
