There is always this - if you can find a data-sheet.

I just ordered a pulled 1M30D-060 from Dalbani which is based in FL. I\'ve checked around and they appear to be a reliable source that has been around for ages. They\'re not fake proof but, apparently, when a problem occur, they\'re quick to dispatch a replacement.
I can support the fact that Dalbani has been around for a long while and used to order tv, vcr, and microwave parts from them. Am surprised their website is parked. They out of business?

I used to buy parts from Dalbani many years ago, and they were one of the suppliers that sent me counterfeit semis. I mostly bought basic stuff from them like VCR mechanical parts after than, but no more semis. They\'re still in Florida but I\'m sure they\'re not the same company they were.
Same here. Their STR regulators were counterfeit plus their
replacement flybacks didn\'t work.

I recently purchased a second-hand Commodore 1084S monitor to use with
my old videogame consoles (SNES, Saturn, etc.). I\'ve tried the
monitor out and it is fully functional, but there\'s a slight flaw in
the picture. There are fuzzy vertical bars of slightly lighter/darker
brightness (most clearly visible against a black picture) near the
left edge of the screen, running the entire length of the screen from
top to bottom. The bars\' position and size change when I adjust the
horizontal position and horizontal size knobs, so they\'re apparently
not actual phosphor burn-in (which leads me to hope that I might be
able to repair the problem). What kind of defect/damage might be
responsible for these bars, and is it repairable?

Hi Alex! Did you ever solve this? Having exactly the same issue with
exactly the same monitor. Thank you in advance!
It\'s been over 17 years since the original message was posted, so it\'s
unlikely that anyone remembers the result even if it did get fixed.

What have you tried so far to fix or narrow down the problem, if
anything?

It sounds like some kind of ghosting or ringing; is there a picture you
could upload anywhere (Imgur or similar) so we can see what it looks
like?

I\'d start by swapping the video cable and also trying a different video
source, just to make sure it really is the monitor at fault. Then I\'d
replace all electrolytic capacitors on general principle. These monitors
are decades old and there are probably multiple caps that have gone out
of spec by now, so just doing the whole lot can save multiple rounds of
troubleshooting.

There\'s a service manual for this monitor available at
http://www.zimmers.net/anonftp/pub/cbm/schematics/monitors/. The scan
quality is poor, but it\'s certainly better than nothing.

Hi Rayner,

Firstly just wanna say to the Google Groups Einstein that the 18 year period doesn\'t matter as long as the problem was solved and the guy is still around on this earth. The Commode/Amiga retro-scene is very much alive.

Now I have posted lots of pics and info in this thread. I have already recapped the monitor and done a lot of measurements.

https://www.edaboard.com/threads/commodore-1084s-monitor-with-faint-vertical-lines.396322/

I thought I\'d also ask here as Alex faced the exact same problem.

Thanks for your time Rayner.

looking over and seeing an antenna


If you depart 17 out of GRR, there\'s a ~2000 MSL tower about 10 miles
south.

One day I waved at a guy doing maintenance near the top of the tower.
He waved back...or maybe gave me the finger, I\'m not sure.

There was nobody doing maintenance but that was the thought that chilled
me -- somebody had to climb that tower. Flying around in a Tomahawk, no
problem, thinking about hanging off the tower, sympathetic acrophobia.

I can\'t fathom wanting to handicap a clear channel station just to make
some smaller station go 24 hours... that seems like one step forward and
two steps back.

It\'s odd to see such an old thread get resurrected, but it is still a
relevant post even if the original participants are no longer reading,
so in this case I don\'t think it\'s anything to get worked up about.

I see from that edaboard thread that you\'ve already tried the most
likely solutions :-(

The slowly drifting *horizontal* lines you mention sound like hum bars,
i.e. excessive voltage ripple from the power supply making its way onto
the display. If this is the case you\'d see two bars on screen at once
(100Hz ripple from a full-wave rectifier, on a screen with 50Hz vertical
refresh) Again, by far the most common cause is a bad filter capacitor
in the low-voltage power supply, but there can be other components at
fault. See https://www.repairfaq.org/sam/monfaq.htm#monrwphb

If you have access to an oscilloscope, you might want to check the
outputs of the power supply for unusually high ripple. In particular,
the output of the 12V DC regulator (IC403) ought to look nice and
stable, as the regulator should smooth out whatever makes it past the
filter capacitor.

Obligatory safety note: be very careful and don\'t work alone, these
things have some nasty voltages inside them (including that 125V DC
power supply output). I highly recommend the safety guidelines at
