Hi Tony!
Here is a link in my dropbox to a picture of the PCB in my convertor.  I
hope this helps.  I would say though if your unit is functioning correctly
at this point, I would not worry about it.  Of course Roy is the expert in
these matters so whatever he says I would consider to be the final answer.
:)  Take care my friend.

Hi Tony!
The PCB in my convertor has no solder mask.  I didn't look to see if there
is some kind of model #.

Wonder what's considered "early?"

I got mine from him July of 2012...

Hi Mike!
The monitor works just fine on a PC.  I used it on a laptop for a long while
that had a malfunctioning screen and the flat screen monitor worked great as
an external monitor!
I just received an email with an answer to my problem from Roy Justus that
says the following.
---------------------------Roy Justus' email-----------------------------
Some early models did this.    A 0.01 mf  cap on the horizontal sync line
should do the trick.   You can send it to me to be fixed or I can just
send you a new one......

Thanks Roy  for offering to fix it!  I appreciate it.  Since I already have
one of his convertors, I'm going to pursue getting this one fixed first.  I
figure if this one can be fixed or fix it myself, why not fix it.  Anyway,
thank you Mike for responding to my email.  I appreciate that as well.  Take
care my friends.

This could possibly be an issue with the monitor itself.  That's the kind of
behavior you see when the backlight or inverter is about to fail.  Try the
monitor on another computer to see if the problem persists.
