Sony DVD player brightness alternates dark to bright
 

I got this as an anniversary gift from my company. Sony model DVD-
NS75H. I searched this group and found nothing on this particular
model. Too much trouble to return, so either I repair or trash. Since
day one when playing a DVD, the picture slowly alternates between
normal brightness, to dark (not black), back to normal, to bright, and
so on. I don't have much experience with DVD players, but was hoping
someone in this group could tell me what they think is happening and
where to start looking for a possible fix. Thankyou as always.

And how have you got it hooked up?

That sounds identical to what happens when playing a DVD player
through a VCR into the antenna jack of a tv set. The VCR being there
to turn the video signal into a radio signal for the tv set. The
problem is that there is copy protection built into some VCRs, and
that starts doing what you describe.

If this is the case, the solution is simple, take out the VCR.

I've only experienced this once and it seemed like a fluke. Ejecting and
reinserting the DVD corrected it in my case. If that doesn't work for
you try unplugging the player to completely kill power, wait 5 minutes,
plug it in and try again. Also go into the DVD player settings menu and
save the settings again - there might be a bad bit saved in the EEPROM.
Check the manual or screen menu to make sure you are pressing the right
key combination to save the settings - changing the settings is
different from actually saving them on many DVD players.

That would be my exact take on the problem too.

....and was mine in the thread above. I really do need to read the
entire group before replying. In this case I replied to a different
thread with the same (double?) post.

The copy protection (Macrovision) is not built into the VCR. It is
embedded into the video signal. It screws up the AGC of the VCR, and
thusly affects different VCRs differently.

Never hook up a DVD player through a VCR, unless you remove the
Macrovision first. Hook the DVD player directly to the TV.

Yeah, strange that Jak. When I replied, only this thread was visible on my
server, so likewise, I didn't see your reply. When I came back tonight, the
other thread had appeared above. The vagaries of Usenet, I guess ...

Not all VCR's will have this issue, at least while NOT recording. For
awhile, I ran a DVD player through a JVC VCR with no problems, as long
as I didn't try to record. It seems as if the VCR didn't turn on it's
AGC unless recording.
