RGB not syncing on Commodore 1084 Monitor [SOLVED]

[Oldsmobile_Mike]

Are you trying to troubleshoot the monitor or the cable?  Try connecting via the composite output from the Amiga to the monitor, does it display correctly then?

[Oldsmobile_Mike]

Yea but only in greyscale

That's as it should be.

Okay, if the monitor displays everything correctly when connected via composite, your problem is most likely the cable.  Sometimes these old 1084's have cold or cracked solder joints on the inside (where the circuit board connects to the connector) which can cause erratic operation, but I'd try a different cable first.

When you say "it's not syncing", what exactly do you mean?  Is the picture rolling or something?  Some of these 1084's have adjustments that can only be made on the inside.  C=, in their infinite wisdom, made about 10 different models of "1084", all of which are slightly different.

According to this thread some models of 1084 have a v.sync pot inside the case, adjustable with either an allen wrench or a flat screwdriver.  IMHO I'd try another cable, first.

Whoa there big boy, try scaling those pictures down, or use the built-in forum tools to attach them to your post.  Makes 'em a lot easier for people to see. :lol:

If you don't have any other testing equipment, try testing the continuity of the six pins on the cable.  A basic multimeter can do that for you.  Make sure they're connecting to the right pins on the 23-pin connector.

You are not the first person to ask these questions.

Never heard of the '6Pin RGB cable' you mention, but maybe such cables were used e.g. in the U.S. or other exotic countries...
:biglaugh: :p

LOL. Never even seen a SCART cable or plug on this side of the pond. Older 1084's connect via 23-to-6 pin round connectors. Newer, less crappy 1084 models connect via a 23-to-9 pin D-sub connector.  Viva la standardization! :lol:

These "less crappy" 1084 die like flies, I have over 10 dead units here with dead flyback.

The older 1084 (with power button at the front) are real work-horses, never had an issue and I use them daily since the 80's (one was used as a bedroom TV for ~10 years).

That power button "not clicking in" seems to be a problem on many of them that I've seen.  I've seen them kludged to stick in with all manner of contraptions.

The newer ones have stereo speakers and a "more modern" style.  Also I'm a fan of the DIN connector over the round one.  I guess to each their own, but IMHO none of 'em are much better than doorstops, hence why I have Indivisions in all my Amiga's.  :roflmao:

I'm currently using a 19" Viewsonic CRT which can handle 50Hz, picture looks great & there's zero motion-blur, which is something I noticed on all LCDs I tried.

I just last night replaced my 37" TV on my A500 with a 50". You know, for games.  

Always hated 50Hz. Too flickery for my eyes. Back in the mid-'90s I had an A1200 that was a European import. Every time that I turned it on I would dutifully use the early startup menu to change it from PAL to NTSC (60Hz). I was thrilled when Euro36 screenmode came out.  What was that, 73Hz, and compatible with my 1084S-D1? Winner winner, chicken dinner!

That's the best thing about the Amiga, no two are ever alike. We've all customized them to exactly suit our needs. Cheers!

It was just a silly idea really, can't imagine it being useful for TV watching or computer use which involves lots of motion, like games.

*cough cough* Productivity software *cough cough*

Not everyone uses their computer just for watching TV and playing games, lol.  :lol:
