Seeking Chip Info from ArchosJukebox 6000 Owners? 18
slazar asks:"I accidently reversed the polarity on the DC power input on my Archos Jukebox 6000. Smoke rose and now it won't charge anymore. I opened it up and found that a chip had been fried. Could any of you possibly tell me what a certain chip is and who makes it? The chip I need to replace has been damaged beyond recognition. This chip is a 8-pin surface mount chip, on the same board as the Stop, play, plus and minus buttons. It is nearest the stop button. It is also near the chips labeled '
IR 1F
', ' I 385-2 2AUXV
', and ' IR 022H 3XSD F7416
'. The chip is on the same side as the LCD connector. The reverse side of the board is depicted here. A great website depicting the Archos taken apart is here, except that it doesn't have the picture I need. I have tried contacting Archos but they are completely unwilling to help me. Any compassionate hardware hackers out there?"

You might be kidding around but if not - the Archos Jukebox 6000 is one of those MP3 jukeboxes - not the old record kind. It is quite a bit different from a real jukebox! Althought that might not be a problem for your friend.

How to get it fixed - lie. (Score:2)
If not, you might try getting it repaired. Typically, they will want a photocopy of the receipt. So, scan it, fudge it (the date), then send it with the warantee reg. Wait a couple of weeks. Then call, verify that they took the warantee reg info, ask them about getting your unit fixed, as you purchased it from the store and it didn't work, right? Right...
Now, of course, if you have been "hacking" on it, as that site seems to suggest - like you did the HD upgrade, downgrade it now, to the original drive (you did keep it, right?). That, or pull the info off the drive you have in it (if it is the original), and wipe the drive. You want it to look as "new" as possible, to fake them out.
If you haven't been hacking on it, and it was a simple mistake - I can't understand why they won't repair it in some manner - but if they won't, then try to fake 'em out.
Good luck!

The really famous line is from Doctor Who; the third Doctor was famous for reversing the polarity of the neutron flow. Apparently the line originated when the actor couldn't remember the scripted technobabble and ad libed. It then became a stock phrase.
Voltage regulator chip... (Score:2)
Since the only constraint on this is that it is a 8 pin part, you've got a pretty huge selection of parts to choose from. If you can't get the part identified, your only choice is to trace out the circuit and see how it's hooked up. While there are a great variety of parts out there, many of them are similar or 100% compatible, so by a careful analysis of the circuit, you might be able to identify its function and find a suitable replacement.
Can you take some good close up pictures and make them available?

If it is a power switch or regulator, it will be connected to the battery/external voltage, and also to the internal voltage. Try to trace these out and see if/where they connect to this part. If you're not an EE/technician or at least have some knowledge of electronics, this reverse engineering could be very hard. Think of it as a way to learn...

You should always assume that some idiot is going to plug something in the wrong way or the wrong hole. Your circuitry should be designed to resist failure due to bad connections... reversed polarity, power to the earphone connector, etc.
But then again, that might knock 5 cents out of your profit margin on a $300 piece of equipment.
I have been that idiot before...

P.S.-- User Idiocy design should also take into account weird things happening when multiple buttons are pressed. I discovered an undocumented trick for your (most but not all) clock radio: hold the sleep button down and flip the switch or press the alarm-set button. You'll see the seconds display! You can then press the hour & minute buttons to freeze or zero the seconds. Great way to sync your clock!
