I recently installed a no-solder mod-chip in my V7 (scph-39003) PS2. The reset and eject buttons function normally, and holding the eject button down does cause the reset light to turn orange and the tray to eject, however the tray stays out and does not automatically retract (futhermore, the console itself makes a nasty high-pitched whine when the eject button is held down). Is this systematic of a damaged mod-chip, or a bad install/console? Also, If it is the mod-chip's fault, is it better to exchange it for a flip-top lid instead of another mod-chip? Thanks for any advice.
