Marquee light probs...

Minwah:

I think I spoke too soon...I have noticed that the picture is still wobbling *very* slightly (you have to look pretty close to see it).  I am not sure what the problem is - the transformer is probably a good 50cm away, although it is near the power cable to the monitor.

Is it still too close to the monitor?  Or could it be the tube itself?  I don't think the latter, as I put some sheet lead between the tube and monitor just to see...it didn't make any difference.

Hi Minwah,

Have you tried a solid state ballast?  I found a company here in the US that makes them:

They have a flicker free startup to do not use a glow bulb.  I wonder if your issue is a power noise issue--do you have a power noise filter on the AC where the marquee light is plugged in so it is seperated from the monitor AC?

Hope this helps,

Alan

Thanks Alan...

I haven't tried any other ballast (I was hoping just to use what I've got really).  I think you might be right about the noise - I mounted the ballast very close to the 4-way power outlet which the monitor, ballast and everything else is plugged into.  Can you just get plug-in noise filters?  I'll have a google...

I used one of these:

You can just cut your fluorescent light line cord and splice one inline with it.  I used some quick disconnect plugs instead of soldering...

Thanks,

Alan


Minwah:

Thanks again - I will see if I can find one in the UK.

Did your lamp interfere with your monitor also?
