Hello !

I have just get a Sony Multiscan 17SF2 but it does not work.
When I plug the cord in, I can hear three small beeps and that is all.
Nothing happens, no picture, no LED... And I was wondering if this kind
of issue was well-known.
My electronics skills are not very good but I would love to make this
monitor work. So if somebody could help me to find some info or give me
clues, it would be wonderful :-D !

Thanks a lot,

Alex.

Forgotten : I have already checked the fuse... ;-)

Maybe a service manual could help me, too ?
Do you know any place to find some for free or at very low price ?

Thanks.

I have found service manuals but they do not help me much.
The beeps I can hear seem to come from the wind (AC transformer ?)...

First of all, replying three times to your own post will not exactly win the
group over!

The SF2 is a good monitor, reliable and with excellent image quality. I run
20" SF2s and they have given me good service, and I have repaired a few in
the past. My main monitor is thr 300SF which is almost identical but has
dual inputs. The 'beep' you are hearing is most likely the squeal of the the
power supply trying to start but failing, so there may be an overcurrent
problem, check for shorts like a shorted horizontal output transistor.

Main faults I've found-

Video cable fails where it enters the plug. Forget about soldering a new
plug on unless you have the patience of a saint. Cable replacement is so
much easier, I cannibalise old monitors and use a bit of trickery to splice
it insode the monitor. It's not pretty but it works and the new cable will
probably be more flexible than the very stiff Sony cable which is the reason
the latter tends to break. As yours shows no LEDs then this isn't the
problem.

Horizontal output transisor and an associated mosfet fail (I forget the
exact P/N).

Open circuit picofuses which sometimes fail for no apparent reason- they
look like a TO92 transistor but have two legs.

Good luck. you'll need it! These are rather sophisticated units and not
tremendously easy to work on.
You say you have limited electronics skill so I'd say your chance of getting
it working is close to nil. Whatever you do, be very careful inside this
monitor- the mains capacitor stores enough charge to stop your heart, and in
a fault condition its charge may not drain off, even after days or weeks.

Hi,

First of all, replying three times to your own post will not exactly
win the
group over!
I know and I apologize for this. It is just I found several new things
after my first post... I would have to think and search first before
writing. Sorry again... I do not like "spammers" too.

Thanks a lot for all these clues and accurate information, especially
for the security warning... I knew that these kind of capacitors are
dangerous but I did not know it could directly kill me.

And thanks again for replying (knowing I have nearly no chance to make
it work !). I am going to print your message... I hope I will understand
it all !

Alex.
