PS2 is on, but no signal

I think I know what happened, when the PS2 hit the ground, it may have detached the internal module that allows you to connect to the TV namely the modulator board or the RCA jacks. The circuit board may even have been cracked. Ok first I am assuming that you are under 18, and if you are there is no way I am going to tell you to open up a piece of electronic equipment to affect repairs on it. Now if you are into electronic repairs or learning electronics I would tell you to open up the unit look for the damaged area, draw out the traces that seem to be broken and jumper them, the problem is PS2 and other gaming syatems use a multi-layed board so some of the traces might be internal to the board itself. So what I'll say to you is open up the unit and if there is too much damage take the unit to an authorized electronics shop that specializes in game consoles and have them repair or replace the circuit board. I hope this helps.

The tray has become misalligned. If you want to fix it on your own heres what you do. Remove the 6 (or 8 depending on generation) screws on the bottom. Remove the warranty sticker on the back by the power switch. With the front towards you, lift the top while tilting slightly toward the front and pivoting it by the power/eject buttons. Either remove the button assembly by popping it off the lid or just be careful not to tear the cable. Remove 4 philips screws from the cd mech lid and lift off. Remove two philips screws from the tray hinge. Lift and slide tray out of front. Push white gear frame at front of tray area to the right and hold it there while you put the tray back in. Reassembly is reverse of disassembly.
