Where are the sparkles?

All over the screen, random places, more visible on darker
picture.

Affects VGA/DVI/AV & RF sources. i.e all.

Are they in the same spot permanently? Probably dead pixels.

Maybe an adjustment (Dispersion, Vs, etc.)

No, Not in the same place at each flash/sparkle - random all
over.

The first thing I would do is check all the power supply voltages.
Make sure they are correct, well regulated, and free of ripple.

Through HDMI ? May need HDMI extender. Had issues with many brands
same sparkles as decribed here.

I just thought I would post an update to my initial question
regarding green sparkles.

Having poked around the voltage inverter board and found
many dead C's and replaced them it is substantially better
and now only shows the fault for the first 10 minutes or so
until the set has warmed up.

I was told to obtain the service manual for this model and
adjust Vset_UP and Vset_DN appropriately and the sparkling
will not show at all.

Anyone got a service manual/document details to set these
voltages correctly?, a quick minor rock on the pots has
improved but it would be nice to know exactly what they are
meant to be set to.
