Title: Amiga on a modern TV
Post by: stevil2k on March 09, 2009, 11:18:42 AM
I have just dug out my old Amiga 1200 and plugged it into a Panasonic TH-42PZ80B TV. Does anyone have any experience using this TV on older computers/consoles? When i plug it in using Scart the screen will roll but it will work over an old RF tv cable.

the Amiga is working fine, it will output great to another high def TV using Scart.

Thanks for any suggestions.

I use an amiga>scart cable, one that plugs into the monitor port on the amiga. works great on 46" samsung. I did struggle to hook via the composite to my av amp though..

I have a samsung A series 26" 720p telly...

I've hooked up my A1200 via similar RGB->Scart cable from the video port.

The picture is very crisp, however there is an intermittent wobble(side to side, as if the screen is trying to reset or something...)

It's pretty annoying to be honest!

I can make it go away by switching to NTSC modes on the Workbench, but games and such like still have a wobble.

Do you have any idea why it does this, because otherwise the picture quality is superb...

I I haven't tried messing with display modes on Workbench, i don't see the point because like you say, most games will run lowres.

There is a picture coming thru on scart, it just rolls and there doesn't seem to be any way to stop it via the TV.

Annoying because it will work fine on my mates Sony Bravia TV over scart and it does look stunning!

I am going to try a scart to composite converter, see if the front TV ports have better luck.

I have not really changed anything from default settings on the tv..

A1200 is standard pal, cable im using is one of these> Amigakit (http://amigakit.leamancomputing.com/catalog/product_info.php?products_id=226)
came with a miggy i bought a while back.. dont think its anything special.

TV is Samsung LE46A656A if that helps?

Heres a quick pic running Turrican 2. Dont see any wobble in the pic.

We don't have SCART in the US, but the composite video output works just fine on a modern TV.

have you tried putting the tv on the scart channel the amiga is connected to. The reason why i say this is years ago i didnt want my tv to detect scart connections on its own so i cut the 12v live on the amiga scart lead didnt stop the amiga automatically displaying its image but what it did do is cause the image to scroll unless i then physically switched to av1!!!! Food for thought.

Also sometimes there can be a few different modes on 1 single scart connector try switching threw them all usually consists of just pressing the AV button repeatedly

It sounds as if your cable doesn't correctly switch the TV to RGB mode. Commodore monitors and good TVs don't need the switch voltage, so not all Amiga SCART cables have it connected.

You really don't want to use composite. If you need composite, you can get it from your A520 modulator or from the built-in connector on the A600 and A1200.

Yeah i tried that, still no luck, tried it on both scart sockets too.

I really dont want to use the amigas composite outputs, the picture is horrible.

Surely the picture would be better if it used the monitor port with a scart cable and a composite converter? The scart cable is very old, perhaps a newer one would give me better luck?

Thinking about it, the TV has a VGA input...... Could that be a better option?

i use an amiga rgb to scart lead, the last time that it started scrolling on my tv, it turned out to be a bad solder joint in the scart lead,
worth a look

I guess i wasnt pressing it enough lol. It seems to work eventually. I have found it works better if i have the Amiga plugged in via composite then change the AV input to Scart on the TV and the picture is stable.

Thanks for the advice, I am having to re-learn a lot of old amiga stuff and it is every bit as fun as i remember it.

I've never had any problems with it. Not as quite ad good as RGB or scandoubler->VGA but on a good TV it gives pretty good quality picture in screen modes like high res non-laced. What's wrong with the picture you get on composite?

I think i may have confused the connectors, I was thinking of the old RF connection when i said the picture is horrible.

The composite is much better but there is a lot of ghosting, still nowhere near as sharp as scart. Hopefully the new composite cable i bought will be a higher quality and reduce the ghosting. If thats the case i will most likely just use it all plugged in via composite.

Yeah, RF sucks. I'd only use that in an extreme emergency.

If you get ghosting with composite, do you have another cable you can try? I've had problems with old worn cables, but those are cheap to replace.

My A1200 looks great om  my 37" Panasonic...it just sits to the left of the screen a bit, using SCART (but no big deal)

I use Super High Res Laced...and there is no noticeable flicker!

Haven't tried mode promotion yet (DblPAL and so on)

I was playing Turrican II the other day and it looked and sounded great

I don't think your composite converter is going to help one bit, since it probably doesn't convert anything to composite at all.

Generally televisions are very picky about what they accept on the VGA connector. Even though all TVs work with 15 KHz signals, they don't do that on the VGA input.
