EZ repair on Sony DVD players...

[Vector Viper]

Found an easy one- applies to DVP-S560D, DVP-S360, others same year?

Symtoms-will not play CD's or DVD's, loads, spins up and searches for a long
time,
then 'No Disk' laser lights and scans, just no read.

Fix-pullout dvd loading unit, including the driver board (plugs into large
main board)

On bottom of it are two orange .8Amp fuses-they are well marked....one of
the 2, or both may be open,
or increased in resistance. Replace and enjoy!

Theory- perhaps bad design from factory, too low an amp value, or just poor
fuses?!
I fixed 2 DVD players tonight from this finding....

Just giving back,

Viper

Expect one or both to be a re-do. There's a resistor mod on these, and if
the fuse was bad, then the focus coil got hot and shorted through. The
pickup is likely already damaged or just bad because they go bad - they had
lots of failures on those.
The resistor mod is anything but "EZ". One of them especially is nearly
impossible to work with.

Yeah, tell me about it...I get DVD's in all the time-honestly, it's usually

the laser
assy that is bad and no fix-which is why I was pleasantly surprised by my
fix...
I had another DVD player come in with no sound, was a shorted SOMETHING on
the sound board,
if you pumped voltage/curent into the line, the sound would work ok, but a
transistor
got hot....never did fix that one, customer, you know...

I take it's 1 fuse for each coil set (foucus and tracking?!)
I played both machines over 30 min with no problems-possibly lucky,
I have seen blown driver ic's as well!

Could you point me to the "resistor mod" you mentioned?

Yeah, maybe just lucky. Keep your fingers crossed. Of those I've seen with
the fuse link open, only one worked reliably after without a new pickup.

Was it a Toshiba?

You should have replaced caps C926, C927, C928, and C929. Replace with caps
rated at 100 microfarads with at least 25 volts tolerance.

The fuses are for the servo controller, which is DSP based. - Reinhart
