Alright, Ive got a n00b question you guys.

My first electronic mod has been switching out the stock eject light l.e.d's for blue ones. Ive got the right side working fine and everything. But the left side is just being a pain in the ass. I finally got it to light up today but all it does is blink. (Mind you I powered it up minus the hard drive and the disc drive. Would it flash to indicate that they werent found? Just thought Id add that).

There are three soder points on the left side. Which ones should be used. The bottom two or the top two. Thanks, you guys have been really helpful in the past and I apologize if this an anoying question.

Okay, here's the deal.

First, yeah, it's blinking because all the parts aren't in the right places. Put everything back together (correctly) and it won't blink.

Second, you should have 6 posts, 3 on each side. The middle post is your ground (-) and if you're looking at the board, the top left and the bottom right are positives for what used to be green. We'll say those are your "normally on" positives.

The other two posts (bottom left and top right) are your positives for your formally-red leds, and they share grounds with the normally-on LEDS. If you cut your old leds out, you should probably put some other led here, just in case there's an error, you can figure out what it is by the colors and the flashes.

Hope this helps.

yep, long leg = positive+, short leg = negative-
oh, and the resistor goes on the long (positive) leg.

if you are replacing the existing led on the p/e you don't need a resistor

well it seems ive successfully fucked up the left side of the chip. I dont have anything to solder the legs to anymore. Guess you have to get it right the first time. This is pissing me off. How much are new chips? Thanks for all the help.

Do you mean the front board? if so you dont have to replace it. i kinda fucked mine up to. all i did is solder a wire directly onto the led (the one that wasnt lighting up) and make sure you connect it to the right pin. use this: user posted image

Ok one more question, then I'll leave you guys alone. I just want a blue led on either side simply to illuminate the eject light fully, dont want it to flash or anything. Can this be done by directly connecting to one of the wires?

it will eluminate it fully without doing any work, it will simply flash on/off when there is a problem.

If you don't want it to blink ever, and just stay blue, you can just bridge the two positive legs on each side (make a tiny wire that connects both the positives on each side together). This way when the xbox tries to blink, the blue LED always gets power. Although, I'm not sure why you would wanna do this. anyway, thats the easy way. the hard way would be to get 2 more blue LEDs and cram them in there side by side.

Ohh well I dont really care if it blinks becuase its loading or something, I just dont want it to be stuck on blink mode, as my left one has been doing. So you just strip the appropriate wire and attach the postive leg? What do you do witht the negitive leg? Just ground it? I think i'll go give it a try, thanks for all the help.

It's all opened up and I'm ready to get to work, but I still dont trust myself. Can anyone tell me straight forward which wires I need to connect the postive and negative legs to? I dont want to sound lazy but I'm still not trusting myself to get it right. Thanks a bunch.

the short leg goes to negative and the long one will go to what ever led got screwed up. if you need more help you gotta say which one you are trying to repair. from the pic view top or bottom left or right.
