A520 Juming Screen Only Before Workbench

[Super TWiT]

I just got my a520 in the mail today (been using monochrome off of a500) and it seems to be acting a little weird. The picture will be in black and white and jump around and then suddenly clear up by the time the workbench screen loads. Once it loads I get a perfect color picture. I took the workbench disk out so it will display the hand with floppy upon boot. Here again the picture is all jumpy and in black in white. Any ideas? I have a kickstart 1.3 a500 with a 1 mb agnus chip and a 512 k expansion in the trapdoor. Everything else is standard. The a520 adaptor came from new york, so I assume it is NTSC. The workbench copy I got is from the amiga forever series (I burned it onto a floppy) so maybe the disk is pal?

I meant to mention that I am in an ntsc region not pal. I noticed sysinfo has said in the past that I'm pal, but even when I run sysinfo in my emulator changing between pal and ntsc settings it still says I run pal. The only thing that remains the same between the sysinfo readings is the wb image. It does sound like its the wrong video format, but if that was the case why would it clear up?

I believe they are both ntsc (how do I check?). If I let the disk request screen wait it still jumps around, and finally there is no picture at all. When I use a game disk it works. As soon as it loads the screen is crystal clear.

I noticed that for maybe half a second when I first start my amiga the screen is red then quickly disapears. Is this a sign that the kickstart is loose?

[Super TWiT]

Is the quick red screen a new clue?

[Super TWiT]

Well, maybe, but the monochrome output works just fine (no jumping picture). I have a one meg agnus so maybe I could switch it? You don't think its a kickstart issue then?

[Super TWiT]

The only thing that got me thinking kickstart is that I noticed that for like half a second the screen turns red when I first turn the amiga on.

Turned out to be my tv. I connected the amiga to my tv and the jumping picture happened. Connected my amiga to my pc via the capture card (same cables) and PERFECTION. Weird problem... It's a cheap polaroid tv that has been known to also turn only one channel on our satellite service purple. I assume it assume the tv won't hurt my amiga will it?

[Super TWiT]

Actually, this seems to only happen with the side inputs on my tv. The back ones are fine.

BTW, I was plugging my amiga into the tv's rear inputs, and I heard a buzzing noise from the tv as I accidently tried to plug the audio prong into the video jack. The amiga was off (power supply was plugged in but switched off), and I had left the tv on. Wikipedia says that RCA cables can cause equipment damage because the hot connection makes contact before the cold screening connection. However, I would think because the amiga was turned off it wouldn't hurt anything right?
