Need schematic or service manual for Pioneer SX-S30

[Bargainhunter]

Does anyone know where I can obtain the service manual or at least the schematics for a Pioneer SX-S30.
The unit does not power up.  It has a switch mode power supply.  I get 12volts but no 35 Volts.

Any help would be appreciated.

Thank you,
Chuck

did you check output capacitors for esr, diodes for short ?
can you upload a (crisp) picture top and bottom of the power supply ?

Thank you for your help.
I'm currently recovering from eye surgery and my vision is blurry.
I will post pictures of the power supply as you requested as soon as possible.

Thank you,

I checked out the capacitors and they are okay.
I do have 5V and 12V.  The unit does not completely turn on.  I do get a display over hdmi but the display on the unit does not light up.
I have asked Pioneer to send me a service manual but they won't.  I can not find a service manual or schematic anywhere.  I saw a post on HIFI-Forum.DE from a rich neuling and tried to contact him but no answer. 
I know this is an old thread but maybe someone came across a service manual since the last post.

Have you been working on repairing this unit for four years?  Is it possible the front LCD has a dimmer function?

[Bargainhunter]

I had eye surgery and put this repair on hold.  I just got around to put it back on my bench.
I will check out the dimmer function to see if the display is turned off.

I'd like a slim-line receiver like this for my bedroom as the speakers in modern TVs suck.  It would definitely need to be able to be dimmed completely if I were to sleep with music playing.

Sadly, these units are a bit expensive.  I'd like to see some internal pictures of this unit.

Internal picture of the unit.
The dimmer dims the blue led lights on direct and net but no fl display.
No audio but have hdmi display but shuts off.

Check PON +5V/0V
to turn on +33V :  PON +5V I guess
If amplifier is not shorted or +33V PSU is operational

reasonable quality : not something trivial like cheap dry capacitors or similar quality related
