Question about HP Photosmart 945 Digital Camera
I was using the camera and it just froze, and now the display screen and red light are flashing and it wont turn off. How do I stop this or reset the camera?
This camera needs quite a lot of power from batteries on power-up.
When it gets older, the grease disappears from the bearings and motors are harder to turn - so motors need even more current. This makes battery voltage to fall too low an camera resets. On reset blinks front red LED and a LCD. This loop can take as long as there is some energy in batteries.
I solved this by connecting the camera to the external power supply (6V, 2A). It boots normaly.
The next step I will make is to disassemble the camera, put some fine grease for fine mechanical parts in every bearing and slide. It should help.
The other solution to test is to mount a small resistor (I guess about 1 to 10 ohms) in series with the motors. This will lower the power-up current. But also all movements will be a bit slower.

I have tried all the above solutions to no avail. Where can I get my unit serviced?
