Fuzzy MultiScan 15 display
Posted by: Gil on 2008-02-23 05:53:06
Hi,

I have an Apple MultiScan 15 monitor, which i've had for about 3 years now. About 2 years ago, the image on the screen would turn "fuzzy" for about 10 seconds, then it would go back to normal, then it would keep cycling over and over again. Last summer, I took it out of storage and hooked it up. Same thing. I want to hopefully fix it again so i can use it. Any ideas?

Is it making a noise when it goes "fuzzy" ?

it makes a very faint humming noise.

Just a guess....bad power supply.

Any ideas how to replace it? Or should i just sell/chuck it?

Is it possible that this may be some kind of radio interference, ie is there something nearby that could be causing this regular fuzziness? Someone I know once saw this on a TV at an air base, which went fuzzy every time the rotating radar dish turned towards it.

I guess its possible. I'm not sure how i could test it "interference-free", unless i took it outside, but not in this 30 degree weather. 😛

I've had it in the basement, with most of my other computers, including the wireless router. I've had it in the living room with several cordless phones, a microwave, and a TV. I've had it in my room with a TV and cordless phone. It's a wonder how my family isn't poisoned by radiation. 😛

I have a pencil sharpener that makes any CRT screen nearby to flicker when it's on.

But it does sound like a bad power supply.

I had one of those monitors that would lost the red in the picture after 3 years of having it.

Sometimes a few good smacks on the side would clear it up [😉] ]'>

It might be worth trying to find another one. They seem to be quite common in my experience and many times I've had to leave them sitting because I have no space for any more! However, I do tend to nab the detachable VGA to Mac cables from the back as they are very useful for KVM switch setups.

With the price of 15" LCD VGA monitors today I'g just get an LCD monitor and an adapter. I don't have a CRT hooked up to any of my non compact Macs.

Some of the non-Sony CRT equipped Apple displays use a connecting cable with a VGA-style DSub connector at one end and a Mac-style DSub connector at the other end.

It is a good idea to keep this cable and use it to connect a LCD (analogue input needed). It works well for an EIZO L365 connected to a ViewPowr 1400/16 video card. No fuzz with adaptors 🙂
