Amiga 2000 Display & Work bench problems!

[CalvinH]

Hey all,

I am writing in response to this thread:

http://eab.abime.net/showthread.php?p=509730#post509730

Thanks to all that contributed but I have new problems! I managed to snap up a used UK amiga 2000 PSU from ebay (as well as a new cd drive) and I have replaced the existing american PSU with the new one.

The machine now boots and seems to run OK as I can see it on my LCD. However, to get any video out put (as I dont have an amiga monitor) I am using a modulator (Amiga 520, RF cable output) on the video out in conjunction with an LCD TV (this tv works fine with my commodore 64). I couldnt get my TV to tune to any of the other outputs (Video out on either the modulator or the motherboard).

The monitor tunes and can display the output, but it appears in black and white and is abit fuzzy. I am not really sure how to tackle this! Will I need an amiga screen? Or is there some adapter I can buy? The screens I have a Commodore 1701 available, can I get it to work with that? Hmm.

Anyway, when it books, it asks for the work bench disks. I didnt expect it to ask for the workbench disks as it has the internal harddrive. My uncle suggested pressing F at the boot screen but I haven't tried it yet. Any ideas?

Peace,

- Calvin

There's a small switch on the side of the 520. Some TVs need this flicking over. Have you tried that?

Also with the 520 you've also got av video out on the side of it. Have you tried connecting that to your TV/monitor?

Video out from the motherboard is definately Black and White only

Hey,

I tried using the mono out on the back of the machine (next to audo left/right). I couldn't get any signal from that so I grabbed the modulator (520) and stuck it into the video port, using my RF cable from my c64, I pluged it into the RF socket of the modulator and into the RF socket of my TV. The result was a very fuzzy black and white workbench image (prompting to insert floppies). Anyway, I do not have an AVI/SVideo composite to check the other side of the modulator but I will get one ASAP.

More importantly, I was wondering if there was any problems related to the machine as it is a US import. I was under the impression they run at different refresh rates? And anyway, this does not solve my work bench problem

I'm sorry to say that I can't help you with that as I've not owned any NTSC stuff.

On the 4000D there's a connection on the motherboard you can switch from PAL to NTSC with.

I've got my old 2000 manual somewhere - I'll try and locate it and have a look.

PS - have you got a video recorder or DVD recorder? They have composite inputs

PS2 - Are you sure that it's a PAL 520 and not an NTSC 520?

On some versions of A2000 there is a solder pad near Agnus who is the NTSC/PAL switch.

Oh wow I didn't know that!

Now that will explain why I can only get my A2000 to work on one of my 3 LCD TV's !!!!

Hey,

I just did a bit of reading and took my machine a part to have a look, I can't find the bridge your talking about or the jumper J102 as discussed on this page of the amiga hardware guide:

http://www.amiga-hardware.com/showha....cgi?HARDID=17

I have an old revision too, before 6.4 ...

[rkauer]

Any revision over 6.0 have the J102 jumper, that's for sure.

Open the 2000, remove the PSU/floppy/other 5.25" device cradle and look near the crystal, in direction of Agnus. It will not "jump" into your eyes at first.
