When I connect my Magic3 to my console, I'm getting a black screen and no sound. When I disconnect it, the console works fine. So why don't my PS2 initialize with chip connected ? I've doublechecked my connections. Used the Magic3 V3 diagrams of China-Magic and the Magic3-code of Robot.

Please gimme some help !

what diagram are you using to connect the magic 3 to the board, chip pin numbers etc. and are you using a resistor/capacitor/anything on the reset line ???

works perfect in v3 and v4 to. no problems. try the tipps with alternate W point, 33 or 16 k ohm resistor and 1 uF or 10 uF capacitor. all my installations an the one of my friend are working with homebrew magic 3. :)

Having a resistor 33k on Resetline, but even when I cut this connection it's the same thing ! Diagram as shown on China-Magic (http://www.china-magic.com/magic3/diagrams/MAGIC_III_V3.jpg)

Homebrew SX28AC (newVer.) DIP...

Used a 50MHz resonator+33k+15pF on OSC

What is the little chip with the number 103 on it where point "Z" is ? Could be i've damaged it... Is it a Resistornetwork ?

Hm, my Tray opens but doesn't close...

looks like a transistor from the picture, and could easily be damaged if you had any shorts or too much heat on it

I think it could be a Resistor, 103 could stand for 10k

there are 8 pins on it, the right ones are all connectet to 3.3V
the left ones are going to the chip left of it.

So i thought this could be 4x PullUps ?

The PIN on the bottom is going down from 3.3V to 0V while I'm pressin the OPEN-Button

if thats the case it could well be a 10k resistor bank then, holding the inputs to the associated chip high, if you get 3.3v at each other opposite terminal, then they should be ok.

ok, it is a 10k resistorbank. connection to the chip is ok. I have dissoldered all wires but still the problem with my tray.... it openes but isn't closing....... SHIT.... can someone help me please ? does anyone know what points I could test ?
