Can anyone decipher this text? I think what it is telling me is that if everything is o.k. and the brightness is still low, then de-solder the LED D504 and then I should have a good bright picture? This is from the G05-802 FAQ manual.
Spot Killer
The Spot Killer does not seem to cause much trouble with the exception of the LED, D504. It
cannot be checked by the usual ohmmeter method because it reads infinite resistance both ways.
If your dipswitch test pattern does not want to come in, or your brightness just doesn't seem bright
enough, and EVERYTHING EVERYWHERE else checks good, pull out D504. Chances are you
will have plenty of brightness.
Poor brightness with retrace lines could mean a defective D504, or perhaps the "Z" signal wire is
not connected properly to the base of Q504.
