Re: 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.

What does charging flash on photosmart m537 mean?

The flash gun needs to have a high charge available before it can flash - this can take a few seconds to charge fully ready to give off a full flash "flash" As batteries get older and uncharged - it takes longer to reach the correct charge on the flash
Hope that helps

I contacted HP tech, after trying several resets and other setting changes, I was informed that it would cost more to fix the camera then its worth - No longer under warnaty.
I can use the camera as long as I disable the flash.
Go out a buy a Canon, I did and its a lot better camera.
