I’ve got a RC9500 from eBay (great place to buy a pig in a poke). The remote operates like a charm, is in excellent cosmetic condition, but one issue makes me very upset. When the LCD backlight turns off it fades out normally but at the very last moment it lights up at the full brightness, for a couple of eyeblinks, then shuts off. At the same time button’s backlight fades out normally. I’ve tried to reload FW, disconnect battery, push reset etc.
I’m not a newbie with top Marantz remotes and delicate electronics in general but without a diagram or a service manual I don’t dare to seek the faulty SMD component on the PCB (I hope it might be any capacitor or so and not the processor).
Could you be so kind to give me a clue what might be wrong, is it a widespread defect or am I the one so “lucky”? What worth is to try to fix it?
Thank you in advance.

UPD: Just tried to load old Firmware v3.2.1.7 and glitch dissapeared. So, the hardware is OK I presume. Unfortunately after loading back FW v3.10.5.0 from the local File Area, faulty fade out has returned.
I wonder is anywhere newer or custom version of FW? Does anyone else among RC9500 users suffer same trouble?

Not that it probably matters now but mine does the same thing and i'm pretty sure this is common. I have never considered this a fault and i'm pretty sure all the units i have programmed have done the same. Just one to live with i think.

If the old firmware works better than the new, why not use the old firmware? If there are bugs in the older version, they will eventually show up, or you might be lucky and not call on any of the things that didn't work well with the older firmware.

Great idea,pal, except the fact that the old FW doesn't allow to acces the full amount of on-board memory.

Thank you Doctor! :)
Your answer soothes me, but, on the other hand, we have an annoying glitch that forces to use the old FW with memory "circumcision" issue. So very strange that nobody here had discussed this malfunction in the days of RC9500 glory.

Maybe in the early days of the 9500, people were creating shorter programs, but in the later days, they were making larger files. The later days would have had people using unique artwork from device to device, rather than the same artwork over and over. More artworks equals more need for memory. And if the Pronto developers heard squeals for more memory, they might have given it to us at the cost of memory not being used for, for instance, fading out.

Right now, DirecTV receivers have a similar situation. They recently changed the menu graphics to high definition, but as a result they can't output menus in standard definition on the standard definition outputs. They gained HD in graphics and lost something somewhere else.
