The 4000 has its issues but over all is a great machine. Make sure that you take the cover off first thing and look at the battery. If its still the old barrel type remove it immediately and hopefully it has not already leaked.

The Indivision AGA from Amigakit is your best option for video then you can use any LCD on the market.

can you explain a bit more about those "issue" please?

As Mike mentioned above the fan, Also the battery as I talked about.
Other issues that cause problems is due to age, the memory sockets are horrible and they become unstable after some time (cleaning the ram contacts with an eraser helps).
many of the capacitors where installed backwards on the motherboard as well as the 3640 board. This will eventually case failure.

The A4000 has a PAL/NTSC jumper on the board you can either switch the jumper or make a toggle switch.   iirc there are some games that switching in the early startup menu wasn't good enough.

So putting a toggle sw on these two contacts will keep in in PAL or NTSC depending on where you have the switch set? Now that I have changed the startup and have the reboot line in there to accommodate the new libs PAL wont stick in the early startup menu if booting into workbench so this would be a good workaround.
