| My LCD screen broke, I know I'm not alone, so at dwihno's suggestion, I'm  | ||||
| typing up this information so everyone else can benefit too. | ||||
| 
 | ||||
| Okay, your LCD is broken, but the 'box still works. Now what? | ||||
| 
 | ||||
| PART 1: Getting a new screen. | ||||
| 
 | ||||
| You're going to need a new LCD, but odds are you don't have a clue where  | ||||
| to get one. | ||||
| 
 | ||||
| Part number: G112064-30 | ||||
| Manufacturer: Shing Yih Technologies, Taiwan | ||||
| 
 | ||||
| Unless you're buying a few hundred, I don't think Shing Yih is going to  | ||||
| listen to you. Instead, I recommend you shop at: | ||||
| 
 | ||||
| http://www.newmp3technology.com/ | ||||
| 
 | ||||
| For me, a replacement LCD was $24USD with shipping. (Archos wants $60  | ||||
| minimum just to look at it.) | ||||
| 
 | ||||
| PART 2: Disassembling the Frame | ||||
| 
 | ||||
| This is written up well on the rockbox site, but you will need a #10 Torx  | ||||
| bit (check your hardware store) and a small Phillip's head screwdriver to  | ||||
| take the box apart. | ||||
| 
 | ||||
| http://rockbox.haxx.se/mods/disassemble.html | ||||
| 
 | ||||
| PART 3: Desoldering | ||||
| 
 | ||||
| There are a total of eight points you will need to desolder. They are  | ||||
| three on each side of the metal frame holding the electronics, and two at  | ||||
| the top end. The side points are structural, but the top two (which are on  | ||||
| either side of the microphone) supply power to the hard drive. I am not  | ||||
| going to tell you how to desolder a joint. That is up to you. I found it  | ||||
| helpful to use a small tool to lift up the joints as I worked, seperating  | ||||
| the side ones individually and then gradually working out the top ones. I  | ||||
| certainly hope you are more competant at desoldering than I. | ||||
| 
 | ||||
| The two electronics boards inside the Archos are connected by a paralell  | ||||
| connector, much like the one you find on the back of your hard drives,  | ||||
| though without the cable. This is why even desoldered the boards will  | ||||
| stick together. Carefully seperate the two boards. They are connected by  | ||||
| several wires. Don't break them. | ||||
| 
 | ||||
| NOTE: The two connections at the top (by the microphone) have wires  | ||||
| embedded in them. This won't make your life any easier. | ||||
| 
 | ||||
| NOTE: If you remove the tape in the battery compartment while you work,  | ||||
| make sure you replace it with something afterwards! (A couple strips of  | ||||
| simple scotch tape worked for me.) | ||||
| 
 | ||||
| BE CAREFUL not to break the end boards off while you work! | ||||
| 
 | ||||
| Again, the rockbox site has some handy pictures, though this section is  | ||||
| for the non-recorder model and is a bit uninformative. | ||||
| 
 | ||||

| 
 | ||||
| PART 3: The New LCD | ||||
| 
 | ||||
| Remove the old LCD cable. There are two little clips (one on each side of  | ||||
| the connector) that can be gently pushed out to free the strip connector.  | ||||
| When you put the new LCD in, make sure you have the right orientation  | ||||
| (duh) and also make sure the connection is tight before you clip it back  | ||||
| down. This part is probably the easiest of the whole affair. Be careful  | ||||
| with the plastic frame under the LCD, as it seems a bit fragile. | ||||
| 
 | ||||
| PART 4: Test! | ||||
| 
 | ||||
| Don't solder it all back together yet. Re-seat the top electronics board  | ||||
| so the parallel connector is snug. (Watch out for those pins by the  | ||||
| microphone! Now you can plug the unit into the AC adapter to see if the  | ||||
| LCD works. You should get a message on the LCD saying "ATA Error" or  | ||||
| something to that effect. This means the LCD is sitting correctly and you  | ||||
| can proceed to reassemble. If not, go back to part 3. | ||||
| 
 | ||||
| PART 5: Resolder | ||||
| 
 | ||||
| UNPLUG the archos. (Just thought I'd better reiterate.) | ||||
| 
 | ||||
| Resolder the two top connections (the ones by the mic). | ||||
| 
 | ||||
| PLUG the archos back in. The hard drive should spin up. Nothing much more  | ||||
| will happen until you put the batteries in though. (I think, I can't quite  | ||||
| remember.) | ||||
| 
 | ||||
| Okay, good. Unplug the Archos again. | ||||
| 
 | ||||
| IMPORTANT: When you resolder the frame points, make sure you don't leave  | ||||
| any pointy bits of solder poking into where the batteries run. I did, and  | ||||
| they scraped the plastic off my batteries, shorted out against the frame,  | ||||
| melted the inside of one of the bumpers a bit (smoking and smelling  | ||||
| awfully) and just about scared me to death. This is also why you need to  | ||||
| put the tape back on if you removed it. | ||||
| 
 | ||||
| PART 6: Reassemble the Archos! | ||||
| 
 | ||||
| Put the archos back together, taking care not to bend anything. The rubber  | ||||
| bumpers are tricky, but I think there are some notes on the rockbox site  | ||||
| about how to put them on the right way. | ||||
| 
 | ||||
| Victory at last! You're done! Now go to the rockbox site and update your  | ||||
| firmware, I bet it's out of date! | ||||
| 
 | ||||
| CONCLUSION | ||||
| 
 | ||||
| In the end, this cost me much less than sending it in to someone  | ||||
| qualified, but was also a hell of a lot scarier. I think I learned a few  | ||||
| things about my Archos though, and I look forward to trying some of the  | ||||
| other mods. | ||||
| 
 | ||||
| I'm sure there are people out there (real pros) who are horrified at what  | ||||
| I have written. Please, correct any mistakes I have made in this document  | ||||
| so future 'boxers don't have to go through the hours of stress and strain  | ||||
| I did. | ||||
