Problem with TV LCD Samsung LN22A450

[guxtabo]

Hi, I just bought an tv/lcd samsung LN22A450. I connected my ps2 slim 79001 with the tv by component cable (YPbPr), so I put sms with 480p, my tv is 22 inches. But when I connect my usb carry disk wich has power supply itself, the tv says NO SIGNAL, and when disconnect it, it doesnt and show image.
It doesnt do that with my kingston pendrive, and either with my crt tv.
Any clue or solution?
Thanks everybody.

I've found my fat PS2 wont boot from disk normally with the pen drive inserted but it will boot from Memory Card.. this may have something to do with BOOTMC..

I dont know why this happens, the drive is spinning, power lights on, but blank screen.

I've found its best when i want to boot from disk that i remove the pen drive first to be sure...

Try getting into sms first and then inserting your pen drive..

Thanks for your reply, but I can boot to sms without pendrive/carry disk inserter. But after sms starts and I connect the carry disk, the tv loose signal. But not with the pendrive.
Would it be because carry disk steal power to the ps2? I guess, even it has its own power.
Please comment, people.
