HP Photosmart 635 Digital Camera -- when put in batteries, camera beeps and image display keeps flashing

SOURCE: Flash Will Not Operate

Flash doesn't operate from various reasons. Try to reset your camera if you find in the instructions manual a procedure like that. If it doesn't work here are some possible reasons. The flash works because a power inverter will charge a capacitor at about 350 volts. These are required to make a small lightning inside the flash tube. If the capacitor is damaged it will not charge, and the flash woun't work. If the invertor is damaged, it woun't charge the capacitor, and without those 350 volts the lightning inside the flash tube woun't go on. If the components that links the the camera's internal processor to the inverter circuitry doesn't work because of some failure to those components, again the inverter woun't work. Any shortcircuit or open circuit or imperfect contact can result in this. Even if the camera's firmware was corrupted in some way it could fail to instruct the camera to charge the flash circuitry. As you can see there are many reasons for that but only a service center can make the correct diagnostic. It isn't adviceable to dissasemble de camera yourself and tamper with the invertor circuitry as you are exposing yourself to those 350V. You may get some nasty electric shocks or damage other components. Therefore, I think the best aproach to this problem is to have it diagnosticated and fixed by a specialised service facility.

SOURCE: Battery Life

This is a typical problem with these cameras. The culprit is a failed onboard battery. The battery is for retaining the time and date while replacing the removable batteries. If you put batteries in and set the time and date- then remove the batteries for about 30 seconds- put the batteries back in- if it asks you to set the time and date again the onboard battery is no good. If you remove the onboard battery your camera will be very usable and the batteries will last 100 times longer. If you can change the batteries quickly you will not have to set the time and date because there is a small capacitor that will retain a charge, in other words it works better without the battery. I have done this to about 15 of these cameras and all worked great afterwards. You will need a precision philips screwdriver to remove the 7 screws that hold the case together. The onboard battery is small, like a hearing aid battery, mounted on the lower board just behind a piece of brownish cellophane like material. Just cut the material open and look in there between the boards and you will see it. It is mounted flat grap it with some precision long nose pliers or tweezers, wiggle it until the solder joints fail and remove it. Re-assemble and your paperweight is a camera again. If you do it wrong ,which is unlikely, you still have a functioning paperweight.

I've had mine for 1 day, and my answer so far is nope, at least I have not figured out a way yet.

Remove the batteries and SD card for about 5 minutes. Reinsert and see if that resolves the issue..
