This fixed worked for me when I put a 1.6 in the wrong case! Had no power at all, I just pulled a transistor from a logic level converter I had laying around as it seemed like a likely drop in replacement and after some messing around getting the transistor to lay flat I soldered it in. Then I removed the extra metal tab from the case and reassembled and it booted right up! Thanks very much for this video! :-)

Thanks for: 1) Doing this with a regular & cheap conical tip that most people will actually have. 2) Not editing or redoing the removal of the transistor. It's always incredibly frustrating trying to do a "simple" repair by referring to a KZread video, but where the uploader: * Uses perfect / brand new parts. * Has a huge well equipped workshop with expensive / specialist tools, that most people won't have or aren't willing to purchase for a one-off repair. * Edits out all the ugly, fiddly bits that end up causing a problem when you try to do it yourself. Is there a way to visually see that this transistor is causing the problem? Similar to the way capacitors bulge (and leak).

Hey, no problem that is exactly what I was going for when making the video. The answer to your question is unfortunately, no there isn't really a way to tell visually that the transistor has gone bad. There is another to test with a multimeter though, look here kzread.info/dash/bejne/lGSepbesldG0o7w.html thanks for watching!

Worked for me! Transistor must have blown when I was changing HDs in a 1.6 and this vid helped big time. Thanks to you and Digi-Key for keeping the OG Xbox alive.

2024 - and just fixed a 1.6 with this guide. For anyone reading this, I used low melt - long maulten on each leg, once its mixed in with the microsoft stuff, just touch the 3 points while giving it a wee lift wae tweesers. Thanks for the vid.

This totally works. I recommend using two soldering irons to remove the part without a heat gun since there is a cap right next to it.

Hi! I just got a non-working Xbox trying to repair it. It's a 1.6a inside an older case so I think that's the main problem. It's not turning on at all. Checking the PSU cable that goes to the mainboard, I only get about 3,5V from the orange cables and 0 in anything else. Is that related? How can I check the voltage on the transistor if it doesn't turn on? Thanks

Thank you very much! Mine had the same exact issue and by replacing the transistor it came back to life (it was not powering on AT ALL). You can also use a regular non-smd version like 2N3906 and works just fine (just be carefull with E B C connections)

bought a used 1.6 (manufactured in Aug 2004) and it worked great. I was using composite. I decided to get a 3rd party component cable to get the most out if it on my crt. First time I tried with component cable, I got a unstable image, and the system shut off after 4 seconds. Tried again and same thing. I revered back to composite and booted up the xbox after a 20 second break and it worked great. I played it few times and no problems. Returned the cables and decided to stick to composite. Tried to power on the xbox later that day and it stopped powering on altogether. It really made me sad to see this happen. Any suggestions would be awesome. Thank you

Question: My 1.6 died a little while back and I replace the five leaking capacitors on the bottom right side of the board close to the power supply. Removing the solder to do so, was very rough and the areas for solder became black a few places, but since it powered on for two minutes I am not sure if I am the one causing it's current failure. Could this transistor be another reason as well?

Would the meter return a result value if the system won’t power on at all? Like not even for a brief second? If not is there a way I could still test the transistor to see if it needs to be replaced?

I just tryed to put a 1.6 board In a older case and have the exact same problem demonstrated here, whoops. I Ordered the transistor from eBay and have my fingers crossed. thanks for the video, very helpfull.

I hope you can help me. I bought a second hand 1.6 ( Aug 2004). It worked great until with composite but I bought 3rd party component to improve the Picture on my crt. I hooked up 3rd party component cables to it. The picture with component on a crt was broken, the disc drive opened halfway and system shut off. It did it again. Then I left it for 30 seconds and reverted back to composite and it worked as before. But it stopped working after that. Any idea what happened. I keep thinking those 3rd party component cables bricked my system. Plz respond.

witch one is it that has 2 fans one in the back and one on the board i have the one with 2 fans and i dont know what model it is because the sticker is faded and you cant see the model and i need parts.my xbox has a power light and its green but i havent got a screen the start screen wont come on i was going to try to find the same model that doesnt read games and change my disc drive.......if its the same......can you help me

Mine won't turn on, I'm getting .8 volts on that transistor with everything plugged in. Is that normal if the Xbox is off. Not sure what to check next. Replaced all 5 bulging caps on the motherboard.

The damaged transistor would result in the Xbox not powering up at all. The problem you are having is your Xbox is fragging and it could be the result of many different things. Check for solder bridges on your motherboard and clean them up, check for leaky capacitors and replace them if they are bulging.

When I visited El Paso not too long ago (it was back in May), after hooking up the Xbox, I press the power button and it won't turn on right away (which doesn't make sense since the original Xbox always turns on right away after pressing the power button and the eject button since I first got it for Christmas 2004). In order to power it on, I have to hold the power button for a while until it starts boosting up. After it powers on, it starts working. Is there an problem with it? It was in great shape since December 25th, 2004 until I encounter with this minor issue (and I have a version 1.6).

The smd code for the transistor that goes bad (At least on my 2005 1.6 manufactured in China) is "2T" you can check more info in this link www.s-manuals.com/smd/2t Is a PNP transistor in a SOT23 form factor that can handle up to -500 mA of continuous current. I have not been able to find that exact part, but in my 1.1 Xbox I found this one www.s-manuals.com/smd/a1 Is an A1I transistor that is on the back side of the mobo just at the left of the single row powe supply connector. There are two of them, so you can mess up once an still have a chance, but do not try to power back that 1.1 Xbox before getting the propper replacement for him!. The only difference between this two is that the second one handles only -200mA of current so it will work but you still need the propper replacement, soon or later the A1 is going to die from overcurrent.

Floydzabarber Hello Floydzabarber, I have a v1.6 with almostly the same problem, because it won't turn on, but the problem is that I've tested the 2T transistor with my multimeter, and it deliver 3,40v ....... Maybe there is a short anywhere ?

satchsatch33 It sounds like you have a different issue then. I would check all of the voltages being delivered by the power supply, it's possible that your power supply is the cause of the problem.

Thanks :) I have tested with others v1.6 power supply boards and others front panels and it still doesn't work....so I have tested once more with my multimeter the 2T transistor who seems to work (3,27v stable) and p/e continuity trace (it seems to works to)....but my motherboard still won't power on....any issue please ?

Are you getting any kind of error code with the front panel LED's or number on your display?

I threw away 2 Xboxes because I have this problem :(

Im glad you admit your making a mess. Everyone has to start somewhere I guess. Honestly it isnt as bad as i have seen. You should of used the wick on removal of the chip. That way you wouldnt of scored the board by keeping the iron on it so long. Maybe you know this by now since the video is old. But this comment may help some people coming across the video. Anyway, good job for what you had to work with. I would be also not leaving any bridges like that. If that via was not part of the circuit. You would short out your board.

Got an Xbox that Beeps but won't turn on

Oh my good god you actually did have solder wick & you still did all that horrible mess with that transistor, what in the hell

Have you ever tried to remove a smd component with solder wick? It's not what you want to use trust me.

I brought mine to an electronics repair store and the reason it wouldnt power on was actually that it had bad capacitors. He told me the other reason it happens is a bad power supply.

Hi @MJ306, I think I might have the same issue from an Xbox I picked up at a swap meet. Just wondering if you’d share what you paid for the repair so I know what to expect? I paid quite a bit because it was the Halo special edition and tested it there but when I got home it would no longer power on.

Thank you. I did what you showed and replaced the transistor, it's showing 3.2volts now but still no power on (no fan or anything). Any suggestions anyone?

Check the power supply to make sure it is getting the correct voltage on all lines.

Solder wick doesn't actually work that well to remove surface mount components. I use to use low melting point solder and now I use hot air. The whole point of the video though was to show people that might not have those kinds of things how they can remove smd components.

:D

you can read in Spanish

Do yourself a favor and get a pro to swap this for you if you’re not accustomed to using low melt solder or a hot air station. He could have severely damaged neighboring components and created an even bigger problem. Watching this removal made me cringe, big time.

Well I tried to use tools most people would have at their disposal, that Is why it took so long. I could have used some chipquik and had the components off in a couple seconds, but not everyone has chipquik. Sorry for trying to be helpful I guess

Floydzabarber dont be sorry. You didn’t do anything wrong. The only reason why i have all these thing is because i do mod work myself so tools of the trade.
