    Hi

    Thanks for the info. I was hoping to pay "internet" pricing for this item. Usually the manufactor has inflated the price of everything.

    Thanks

I have a canon powershot a640 but it only takes pictures if the flash is off. How do i fix this ?


Sounds like the flash capacitor is not charging. Usually the cause is a blown fuse. This is a hardware problem, not software, and the only solution is to take it apart and replace the fuse (it's a SMD fuse and it has to be soldered). Sometimes the problem is with the flash board. I'm afraid you will have to give it to a camera technician. I could help you with the repair, but I'm in Germany.

A white piece fell out from the spot next to the memory chip of my Nikon coolpix P4 camera, now the camera will not turn on, can you tell me what this piece is for and if my camera can be fixed, thanks


if you feel technically inclined you can open the camera carefully and take it apart to the point where you can remove the upper circuit board ( NOTE 1: make a careful note of every screw you remove since they are different size and need to be used exactly in the same order) and then the small black plastic assembly above the circuit board below, you can see the defective switch on top of the 2nd board, remove the plastic part of the switch until you see the bare 2 contacts on the circuit board, solder a small piece of wire to bridge the contacts, now very carefully reassemble the camera observing the exact order of screws used, see NOTE 1. If everything is back in order insert the battery and the camera should work now.
note: should you not be inclined to do this work and want to sell the camera as is for spare parts I am interested, drop me a note at: cocnutray at yahoo.com. A Nikon repair shop will charge between $80 to $110 FOR THIS TYPE OF REPAIR, THEY WILL ACTUALLY REPLACE THE DEFECTIVE MICRO-SWITCH. HOPE THIS HELPS :-)

Canon powershot sd1100 water damage..how can i fix?


You really can't....however, there is a very small chance that it might work but you need patience though. First you need to take the battery and the casing off in order to expose the circuit board. Secondly if you can find a dehumidifier, you should run the dehumidifier and place the camera in front of it for 72hrs with no interuptions. Lastly, put the camera back together. Hope this will help. If not, the circuit board has short circuited itself and there is no possible way to replace any components.

Lens does not zoom in


This is not a common error on canon digital. This is caused due to possible short in zoom control circuit (main pcb). At normal use, if the lens does not retract due to mechanical jam, when the zoom control button is pressed, lens error 18 message supposed to be displayed. Since control circuit is shorted and faulty, error 18 message was not displayed. The remedy for this problem probably requires a replacement of a main pcb. Replacing a main circuit board may run around $100-140. -James

How do I clean the interior of the lenz for Powershot A640


Its a big job, If your petty handy, You have to start from the back of the camera, Remove rear cover,Then front cover, Next lcd Display unit, Hopefully your haven\'t put the battery\'s in the camera for a while because the flash has high voltage in it, if you have, You must discharge first, them take circuit board out,Then lens assy, Now the fun part, You have to take the lens apart from the back also, Like I said its a big job, Better when you get this far into the camera you just replace the lens, with a used one form a diff camera (same model )

SD400 LCD Screen White after Replacement


There are a number of possible common faults that can cause the screen problem that you are describing.

It is possible that the new replacement screen is defective, or there is a defect in the ribbon cable, or the sockets are not making proper contact, or there is a cold solder connection at the socket or on the circuit board, or the driver circuits on the circuit board have a failure.

The service tech would try another screen, or ribbon cable (if changeable), or the circuit board to locate the defect. Once he finds the defective board, he will leave in the new replacement.

These cameras are serviced by modular approach.

Videos and photos not all readable by computer when taken on Canon PowerShot A640


You will likely need to use the software that came with the Canon powershot vs. just trying to download via the default (scanner and camera wizard for example) program. If you are doing this already, then I don't know why it is not transferring them over to the computer properly, but if you are not using the Canon Zoombrowser software, you should make sure you load the cd that came with it.

Hope this helps!
