    It's soldered in place. Examine the edge of the shield and you'll see where the tabs stick through.

    awsome!! got the shields off!! thanks for yer help. Just waiting on a few capacitors to arrive. Gonna replace one by one and then assemble, test, reassemble etc.
    I hope this pays off because I read in some threads on other forums that I might have a burnt out backlight or a bad transformer etc. I really hope I can fix this by just doing a capacitor swap. we will see.

    If that ends up being the case, dont worry about it, I know someone who either will have original screens or can do a screen swap with a larger, better screen.

    This guy "thesteve" has figured out some awesome stuff on the express. He and I came up with the switchless region mod chip for the express / gt, and now he's gone on to figure out an effective screen swap and a/v out.

    Look in this thread for some shots of the screen mod:

    By switchless we mean that it doesnt require an external physical switch. Region locking on the express (And other NEC consoles) is done by swapping the 8 hucard data line positions. 1 to 8, 2 to 7, 3 to 6, 4 to 5... So you need a way to phsyically change the circuit paths. Normally this is done with some sort of large multipole switch (an 8PDT to be exact) or with some sort of IC switcher. Thesteve and I designed a chip using a single 10 channel bus switcher IC, but it is still switched by sending either a high or low signal to a certain pin on it. Usually this is done with a physical switch to send either 5v or ground to said pin. For the portable systems like the express though, an external switch isnt easy to mount and usually isnt very aesthetically pleasing. thesteve came up with a circuit / ic setup that basically monitors the status of the "select" button on system boot. If the "select" button is presses, the switch flips to the alternate region mode. If the "select" button isn't pressed, then the system stays in its native region.

    Long story short, the switchless method basically means that if you want to play a Japanese game on your US Express, you just put in the hucard, hold the select button and while holding the button turn the system on. Very clean and simple.
