problem with ps2 modchip

[greet]

I installed the v5/v6 no solder modchip into my ps2 console. I tried to play some psx (not ps2 games cause i haven't backed one up yet) backup games but after the cd tray closed and i pressed x (using the ar2v2 cd2) i just see a black screen ( no noise of cd spinning). What could i have been doin' wrong. I reinstalled the modchip twice. This is an euopean version (belgium. My console specifices are : scph 30004-r PAL.
Any suggestions please?
