How difficult is it to replace the screen window?

About 45 minutes and its a bit fiddly. Bought original screen off EBay £42. Remove battery and SD card. Remove 3 screws from back plus 2 from metal strap bracket, 1 from bottom and 2 more from top button trim. Gently prise camera apart. Loosen 2 screws and slide out screen retainers. Remove Screen backing plate. Remove screen gently pull ribbon wire from camera body. Push new screen ribbon wire into socket - this IS fiddly but you must get it aligned right. Push into place with a plastic spatula - fit screen and protector and re-assemble. All you need is a watchmakers Phillips (+) head driver. Good luck.

Asahi Pentax Spotmatic SP The film rewind button is fully depressed and won't pop out, and the shutter button isn't working.

if the camera is jammed for any reason, then the rewind button will not pop out. on this model it was common that the mirror cock lever at the bottom jumped. in which case the camera will jam up.

remove three screws holding the bottom cover, remove cover. in the middle of the camera is a lever that needs to be latched by pushing it forward. the camera should release and revert to normal usage.

if this is not the case then there may be something jammed in the winding or shutter gears. in which case you would have to remove the top cover and/or front covers.

Lumix camera broken shutter

The whole lens housing will more than likely need to be replaced, you will need to take it to a camera repair store, but the cost will probably more than a new camera replacement. I suggest cutting your lose and buy new.

You need to gently prise off the front speaker grill. You could use a blunt pen knife to do this. After you remove the grill You will see 4 additional screws at roughly each corner of the front panel. Unscrew them and then you can use the pen knife once more to prise apart the speaker housing. Prise the housing apart from the top because two base pads hold both halves together at the bottom. I hope this helps! :)

Hi, I have a F4 one week ago, I've shoot two films, and when i have developed them, i have seen a line of 4 mm wide along the up long side of each photo. Does anybody know what's...

Thanks for the additional information.

Remove the lens and set the camera to manual exposure mode. Select the "B" (or "Bulb") shutter speed. Open or even remove the camera back and hold the camera up to a light source and press and hold the shutter. Look through the camera to see whether there is any horizontal obstruction towards the bottom of the film gate ( = top of negative, they're taken upside down). If you see an obstruction then assess the damage and if it's a foreign body then remove it. Note that you must absolutely not reach through the open shutter. If it closes whilst you have your fingers or tools in the way you will ruin the shutter assembly.

If that test shows nothing, then you really have run out of options and need to send the camera to a service centre for diagnosis and repair. It's likely to be a sticking shutter causing an overexposed band across the negative, usually the width of the band would show some variation in width and position depending upon shutter speed.

A poor battery will not be the cause of a shutter issue. Unless faulty, the shutter will either work or it won't, unlike the previous F3 the F4 lacks a mechanical back-up shutter speed.

I own a Metz 45 CT 1 and I want to change the batteries. How do I get the batteries out?

I take it you mean the rechargeable cells in a NiCd or NiMH battery pack?

Firstly you need to prise the top off the battery pack. This is the end that goes into the flashgun. start at the "flat" side and pull the pieces of plastic on either side of the central divider toward you. They should click out and spring upwards. Work around the battery pack pulling the plastic rim away from the body. You can see where the clips are from the dents in the top plate. Work round towards the back (rounded end). The top will eventually spring off with a bit of help. If the battery has a chrge reminder "switch", remove that bit of plastic and keep it safe for later.

Now remove the long crosshead screw that you find underneath, but don't attempt to prise the unit in half yet. Next remove the battery terminal clips from the plastic. They're a push fit and will probably require some needle-nose pliers to remove. INSULATE THE REMOVED TERMINALS WITH TAPE. Otherwise you may short the terminals and melt something or explode a cell.

Now you can gently prise the two halves of the casing apart. Use a wiggling action and ease the wires down the casing to make room for tilting the two halves apart. (This will make sense as you get the casing apart). The blue and red wires have to be desoldered from the cell terminals before the casing can be completely separated.

You should now be good to remove the cells and insert your new ones. Good luck with that!

Finally reverse the above procedure to reassemble.

My canon powershot a640's flash isnt flashing.

I can't believe I just managed to fix exactly this problem on my camera.  Warning - the process hurt somewhat, but it did work.
I dismantled the case very carefully:  After taking the shiny grey cover on the screen end off (3 screws, noting carefully where each screw was), I took the top cover off.  
That was a case of unscrewing three screws at the bottom of the battery compartment (I left them in place, as it looked tricky to locate them again, subsequently working with the camera upside down), then gently prising the top off - there is an internal clip just next to the visual viewfinder, which you have to wiggle a bit - just use a fingernail to prise it open.  The top lifts off - dangling on with its cable.
Here is the unpleasant bit.  Quite accidentally, I shorted the flash capacitor, by touching its circuit board - and got the most surprising electric shock.  
I looked around to see if there was anything else I would be able to do, felt there wasn't, so I put it all back together, in the hopes that it might have fixed my problem.
Hey presto, I now have a working camera with working flash!

Half picture shows up and top portion is black

The camera firmware should be reloaded, if this fails then the camera is likely beyond end user servicing and should be repaired by a professional.

The reason your only seeing bottom half is as the reflex mirror is opening upwards to expose the sensor ( traditional cameras opened the mirror then a shutter to expose film ) your cameras sensor is only registering or transferring the bottom half of the image because it is the image is registered bottom first to the top until the shutter closes and the mirror returns to resting position.

Your problem could be the result of firmware or a more serious issue.
