A4000T booting

[X-ray]

Also, have you tried the machine without the graphic card and the HD (just barebones) ? See if you can get the purple kickstart screen to come up

The dead lithium battery won't cause this: I ran my A4000T with a dead battery for more than a year (because it is soldered onto the terminals, I couldn't be bothered to prise it out until recently.)

If you remove the hard-disk and all the other boards except the CPU card, you should hear the floppy drive clicking even if your display isn't working. Does that happen? Does the floppy drive click?

It is an A4000T: those are coin batteries that don't leak.

It seems like you may have a display issue, because if the floppy is clicking it is asking for a disk which says to me that you have the kickstart screen up, but you can't see it. Somebody correct me if I'm wrong here.

So...do you have any game disks, so that you can at least see if the audio comes through?

Is it possible that when you tested the barebones system, you took out too many cards? By that I mean that a barebones A4000T system still has the following cards/daughter boards installed:

1) CPU card
2) Ports module (connected by two ribbon cables to the motherboard)
3) Disks module (the one with the internal floppy and SCSI connector and the Micro-D external SCSI connector)
4) AV Module (D-23 video, L + R RCA audio, and 3.5 headphone jack)

If you haven't already tried that barebones configuration (minus any hard-drive and other cards), then try that first. If still no luck you could try to get hold of an RF modulator and see if you can get a display through your TV set. If you want to make sure the whole AV module isn't broken, you could ask a US member to send you a public domain game on a floppy (something with loading music), and you can see if you at least get audio out of the RCA connectors on the AV module.

That sounds promising. Basically, aside from the blank screen the computer seems to be doing all the things it sould be as a barebones system. If nobody closer to you volunteers, I will send you a floppy disc that plays music so you can verify that this is a display issue alone. I also may have a spare AV module that I can lend you for the purpose of testing. Give it a day or two and if nobody offers, PM  me your address and I'll send the disk to you (and the AV moduloe, if I can find it).

You must get that baby working, it is a fine classic Amiga.
