Question about HP Photosmart 735 Digital Camera
The flash on my HP Photosmart 735 Digital Camera Flash will not operate even with fully charged batteries. Help! What are my options to get this resolved??
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.
