re: SR-92

Could anyone help me out? I'm searching for some SR 92 parts specifically the display, any help much appreciated! Cheers Kris

re: SR-92

HI,

Sorry I can't help with the part. And excuse me because I don't know your technical experience. I assume you want to replace the display because it isn't working. Did you check for the presence of the negative 33 volt supply to the display driver chip QU01? Did you also check for the presence of the low voltage AC drive to the filament terminals of the display itself? The other common fault is broken solder connections at the display itself.

My experience with fluorescent displays is that they rarely go bad unless there is physical damage. The usual need for replacement is that they grow dim over time, especially the segments that are on more that the others.

Thanks for the post, I'll bring that up with my Tech when I drop it in, I spoke with a guy at qualifi and he informed me that they stopped making parts about 6 years ago, was trying to hedge my bets, cheers Kris

re: SR-92

Dear friends
I have a receiver Marantz SR 92 and when I'm using, it turns itself off, and after a while turn it on again. Please someone could tell what is causing this problem.

re: SR-92

I have the receiver too, check the speaker system for short circuit or improper impedance or very high input signal on the input, its a protection system
