Question about Audio & Video Receivers
Same problem with an Akai S5000.
Display gets darker because power supply outputs for the mainboard starts falling after start up.
Don't know if its the mainboard is causing the problem or is a problem of the power supply itself.
A S5000 service manual will be helpful.

Mine died after a failed OS update...
After trying to get the update through the USB input and failing, I decided to put the s56v214.bin file directly onto a floppy disk and switch the machine on. It went through a couple of steps which were OK, then showed up the error message 'BAD FORMAT', it continued to work until I switched the unit off and on again.
Now I just get a blank screen and all the buttons under the screen lit. Nothing else seems to do anything.
Basically the floppy lights come on upon power up, and you can hear a blip from the drive as it tries to access something, maybe the system is not finding what it's looking for, or simply can't read the floppy in the drive. I have no idea beyond this. I've tried moving the jumpers on the motherboard (tried every combination with and without the internal battery), all that happened was different lights displaying on the front panel.
I wonder if there's some kind of system reset (most hardware has a combination of buttons you hold while powering up)?
Anyway, if anyone can help out, I would be most grateful.

I've just noticed that one of the caps on the PS is bad so this could be the issue. Planning to get that repaired this wk.
