Your back ups most likely are good. On the magic2 chip, there is a certain thing you have to do to get it to boot. I'll put up a full instruction list for you.
It is assumed that your machine is in the "Off" mode
PS2 games
Press EJECT button to switch on your machine.(tray will come out)
Insert PS2 game in tray, then press/tap the RESET button once.
Tray will close by itself, PS2 reboots and the game will load.
DVD movies
Press EJECT button to switch on your machine.(tray will come out)
Once the browser/system config screen shows. Select and go into browser.
Insert DVD movie in tray, then press EJECT button to close tray.
If the disc is not detected within 3-5 seconds. Press EJECT button to open tray. Once the tray opens fully, press EJECT button again to close tray. The disc should be recognise at least by the second time.
PSX games
Make sure disc (game) is in machine, then power off machine
Now hold the RESET button to start up your machine. Only release the RESET button once you see the first power (3-5 seconds) on screen on your TV.
Your PSX game should now boot (If it shows the PSX game as an audio cd. This means that you didn't hold the RESET button long enough. So repeat PSX loading instructions but hold the RESET button longer this time round when booting the machine)
I hope this is of use to you. I am a professional installer so I know what I'm talking about.
