Changing the crystal is too much work, not worth opening the camera and might not work.

I've overclocked a bunch of ARM router + phone stuff and if you go past a point the proc just doesn't boot.

Well i think it cold be worth the risk . I think i cant resist ;) Just bought a broken 1100d for experimenting.

About 7 Years ago i ylso overclocked my Nintendo Ds by adding a different crystal that could be activated with a switch.

Im also not shure what will happen if we change the clock.

Do you have a broken 1100D? I've been looking for one for a LOONG time  :-\

Before killing it for good, If it does not boot, I'd like some macro pics of every single PCB board and connector in there and run some tests to find the serial (UART) port (by probing the battery bay pins with an oscope or something similar)

Yes shure ! Ill do some photos today / tomorrow if thats ok. Ill probably send it in to the canon service center and see if they replace it.
Its still covered by warranty

I don't think there's a warranty for that.

Nope, that's definitely not covered.
Hardware vendors like to place "water-sensitive paper" that changes color in the event of water damage just to avoid this kind of situation.

Of course theres no warranty for water damage originaly. but maby thell replace it anyway.

Yes like in the iphone ;)

And i guess corrosion from salty water or just mineral water is definitely obvious for anybody who can diagnose a failure in such a device.
I had found a 500D with a 18-55 IS on a used market forum. Shame it had been sold. Both things were not working. 18-55 IS could be repaired with a spare flat cable for AF (did that, so easy to fix mine a year ago) and the 500D looked like it had a dead shutter. You can find it on ebay for about 40 euros and doesn't seem to difficult to replace it.

The corrosion is usually obvious no matter what.

Simon

Yes thats tue ! But ill try to clean everything. Especially the Viewfinder !

Starting disassembly now . Be prepared for photo updates :)

Terrific!
Post the pictures in the 1100D thread

The pictures aren't very clear, can you write down the text from each IC?



nanomad

Thanks for your hard work, here are some commented pics (I need more details on the unknown chips, one of them will probably be the audio IC)











Note: Looks like there's place for an IC, I wonder what that is. Also: lots of test points....

The second one looks like an audio chip (is that a jack and the upper connector for the microphone?) .

I was talking about this.
The form factor of the chip is the one of an audio IC and the connector directly above should be for the microphone.
The one on the right could be the  shutter release, as it is an entry level camera.

Thats for the mic. and the 2.5mm jack is for the shutter release.
