Also, if you're not careful, the top cover will come off completely, ripping a couple of wires off the main board.<br /><br />Anyway, on reassembly I now have a differently semi-working camera; it can now auto-focus, but has no flash, comes up with Err 99 after each photo and has to be switched off and back on again before taking another [and won't take 'rapid-fire' pics], and I'm not sure it can transfer them to the computer, though that was always an issue (computer says 'device driver software loading').<br /><br />I since wondered if a drawing pin might work better as a replacement part than a bent paper clip, or as Posi suggested working from inside the lens area.Jakenoreply@blogger.comtag:blogger.com,1999:blog-1562621284803379652.post-36198995810285049542014-08-27T18:56:39.909+02:002014-08-27T18:56:39.909+02:00Thank you so much for your "walkthrough "...Thank you so much for your "walkthrough " it was so funny to actually fix something and to bring live to the "old lady" again. <br /><br />David<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1562621284803379652.post-57319156555775779832014-06-17T13:20:09.180+02:002014-06-17T13:20:09.180+02:00Hi,

I numbered it, and wrote the numbers on your script; so identifying those screws was easy.<br />- Inserting the flat cables is tricky. I used the paper clip, it fits in the small holes of the cables. Then it was no problem to push gently into the plug.<br />- I popped up the flash a week ago and removed the batteries. Therefore, I was pretty sure NOT to get electrocuted - but was careful anyway.<br /><br />My EOS 300 D will now work for, say, another 30.000 pics :-)<br /><br />best greetings from Kiel, GE<br />AndreasAndreas Jankehttp://fotografie.byto.de/noreply@blogger.comtag:blogger.com,1999:blog-1562621284803379652.post-89772427181185589002013-06-28T18:54:52.853+02:002013-06-28T18:54:52.853+02:00While probably not the most elegant solution to fi...While probably not the most elegant solution to fix the issue, I attacked from the other end. I used the paperclip from inside the lens area to push through where the pin normally would be, then I cut a bit of paper clip off the right length and stuck it in the hole with a very tiny bit of super glue gel on the tip. It took all of 3 minutes, and my Rebel is auto focusing again like a champ. I'll have to keep an eye on the pin, to make sure it doesn't wander, but it looks good so far.Posihttps://www.blogger.com/profile/05215464628648983141noreply@blogger.comtag:blogger.com,1999:blog-1562621284803379652.post-38700093847186891912013-05-09T23:34:39.935+02:002013-05-09T23:34:39.935+02:00Hello

Used the back side of tape to organize screws for reassembly<br /><br />2. Used an analog voltmeter to discharge the flash capacitor (300D service manual shows discharge points - this can be found on the web)<br /><br />3. helped avoid breaking the ribbon cable going to the flash circuit board by disconnecting the cable near the view finder (one screw holding a clamp) and lifting off the cable at the flash button (glue underneath)<br /><br />4. for step 12, removed the black plastic cover (one screw that can be seen in step 9 (exposes access holes)<br /><br />5. When reassembling screws where I couldn't hold them, I used glue stick on the end of the screw driver.<br /><br />Once again, your instructions and photos are fantastic!

Attenzione al nuovo perno in metallo: essendo lucido può generare dei riflessi che sulla fotografia appaiono come puntini rossi (si vedono ingrandendo molto la foto), normalmente sono in basso a circa 1/3 della foto partendo da sx. La soluzione è semplice: basta colorare con un pennarello nero (possibilmente opaco) il perno prima di montarlo (io l'ho fatto dopo sollevando lo specchio).<br />RicardoRicardohttps://www.blogger.com/profile/08586721020368324652noreply@blogger.comtag:blogger.com,1999:blog-1562621284803379652.post-32671312250902795992011-09-20T19:32:48.923+02:002011-09-20T19:32:48.923+02:00It seems to work but alas!

Thanks to you I'm back in action. <br />Instructions were very easy to follow and for once i had all the right tools. I actually printed the instructions and than taped the tiny screws next to relevant pictures so I would have some clue as to where things go. (I am very good at dismantling things but not at putting them back together) Step 22 was quite easy as I used small pliers rather than fingers to get the circuit board out, or maybe i was just lucky. My hubby did assist a bit and gave me a lot of moral support but I basically did the job myself and I am immensely proud right now<br />In any case, thank you again.Danijelanoreply@blogger.comtag:blogger.com,1999:blog-1562621284803379652.post-50700304629555266042011-09-05T20:55:36.238+02:002011-09-05T20:55:36.238+02:00Fantastico!

I followed the instructions here and put in the paper clip bit.<br /><br />However I decided to go further and replace the hot mirror. Unfortunately I broke the piece of glass from Edmund Optics while trying to scribe/cut it (and I'd purposely broken the hot mirror because I couldn't get it out of the plastic frame).<br /><br />So I decided to have "naked" camera - no hot mirror replacement. It won't focus anymore (so the whole sub-mirror repair is pointless) but I was planning to use it for astrophotography anyway (and telescopes have lots of focus travel).<br /><br />Now the problem.. after putting it all together, I get Error 99 every $%#$ time I trip the shutter. When I put it in bulb mode I see that the shutter never opens. The mirror just flips up, then flips down immediately.<br /><br />I'm pretty darn sure I didn't screw around with any shutter connections..orly_andicohttps://www.blogger.com/profile/09177652962226123898noreply@blogger.com
