BIOS Error Beep - Display adapter error (MDA/CGA) ?

My T61p won't display anything. When I turn it on, I just get one long beep and two short beeps (which, according to the table in
this website, - I'm assuming the BIOS is IBM - there is a Display adapter error).
How can I fix this?
P.S.: Before I figured out how to categorize the beeps, I've uploaded a video with the start up of my T61p:

The only cheap and easy thing it can be is a memory chip. If you have 2, try them one-at-a-time. Otherwise motherboard is most likely bad, otherwise, LCD.

Actually, I was informed there is a
ThinkPad General beep decoder.
One long and two short beeps, and a blank or unreadable LCD means:
1. System board
2. LCD assembly
3. DIMM
I've replaced the DIMMs and connected an external monitor to the laptop, and I still got the same beeps so, unfortunately, that means it's the System board's fault...
Luckily my T61p is still under warranty. I know there is a webpage where Lenovo says which FRUs should be removed before sending the PC to a depot. Can anyone give me a link to that page?

I always remove the battery, hard drive and optical drive unless I ask that the drive be re-imaged

And document what RAM and wifi card(s) you have in there, in case they go missing...
