Red light flashing

My photosmart 945 does not seem to be functioning. When I put batteries in the red light flashes and the LCD screen blinks on and off and on and off but the HP logo does not come on and I can't take pictures. I have tried resetting the camera by leaving the batteries out for days on end but no change. Does anyone have any thoughts? thankss

    I have the same flashing redlight problem with my HP 945. I recharged the batteries and was able to take two photos, but the problem is back. Recharging the batteries does not help. I have taken out the batteries and repositioned them, recharged them - nothing will help.

As you continue to recharge batteries time after time they will not hold charge as long as when they were new. I quit using nickel cadmium and went back to alkaline batteries. Have had no problems since the power is consistent until the batteries wear out. Some cameras have a system of red lights that must be on when batteries are working. Otherwise, time to toss, even if there is no warning but camera is not working properly. Change batteries. If nothing works...toss camera! :)

I had the same problem last night. It went away when I recharged the AA batteries.

I put fresh batteries in my sb 600, i took a few pictures and then the flash was not as powerful and 2 red lights kept flashing on the front, why?

Ok, there are several things to consider. First of all, don't use standard alkaline batteries, the flash needs a lot of power and will drain those quickly. Use either lithium batteries (most powerful non-rechargeable) or invest in NiMH rechargeable batteries. Those would be your best choices for AA's.
Now to your flashing red lights - on the Speedlight flash they fulfill 2 functions, one is as auxiliary ready lights (if used as wireless remote flash) but the blinking in your case points to their other function - it blinks 3 times to indicate possible under exposure of your photos at maximum output level. It's basically telling you that the flash was not strong enough to properly illuminate the scene you tried to shoot. That doesn't necessarily mean the batteries are going flat, but you could simply be out of range of the maximum flash power. Your flash has a guide number of 30 - that means at a zoom head position of 35mm (if your lens is at 35mm) and your ISO is 100, then the maximum range of the flash is 30m (approx. 68ft). If your subject is further away, you would get an underexposure warning (3 blinks of the ready lights).
Hope that helps explain some things.

How do you turn the flash on? (with the vivitar vivicam 8018)

Your camera has a built in flash function which enables you to take photos when the light condition is not good.

1. Press the Up button. (for reference of buttons, please see the below figure mentioned)
2. Press the Up button once until you see the icon appear on the LCD screen. This indicates that the flash is forced on.
3. Press the Up button again to change to the auto flash function.
4. The icon will appear at the top of the LCD indicating that the auto flash is turned on and ready to use.
5. Press the Up button again to change from the auto flash to the red eye function.
6. The icon will appear on the LCD indicating that the red eye reduction function has been activated.
7. To turn off the flash function, press the Up button again until the icon is displayed on the LCD.

Note: A “Low Power” message will appear on the LCD screen, if you select the flash function when the battery power is insufficient. To continue using the camera with the flash, please change new batteries

Hp 945 frosen with red light on

I posted on July 16 with this flashing problem and played around and got mine working again.
Originally I would charge through the docking port. What I did was pull the charged rechargable batteries out of the camera and took the charging cable from the docking station and pluged it directly into the port on the side of the camera. The camera started working again. Then while the charging cable was pluged into the camera, I reinstalled the rechargable batteries. After installing the batteries I unpluged the charging cable and the camera still works. I have shot and downloaded from the camera pictures with no more problems. Use the docking for downloading pictures and the side port on the camera for recharging the batteries.
I do not know if this has anything to do with the original problem but I did not have any problems with this camera until I placed it on the docking station with non-rechargible batteries.
Hope this helps.

Flashing lights

I read your posting about changing the batteries. I tried it once and it did not work. Then, I tried it again a few weeks later and the new batteries made it work. I have not tried the rechargable batteries again. I am afraid to remove the batteries I placed in the camera. I hope this helps you. I think there must be a sensor that gets reset at some point and the issue stops. Who knows. Good luck!!!

HP also suggested to reset the camera as follows:
To Reset The Camera:
1. Remove the memory card and turn on the camera.
2. Open the battery compartment and remove the batteries.
3. Wait at least ten seconds.
4. Reinsert the batteries and turn on the camera.

I also found information regarding a similar problem with another model at this link:

Focus Assist Light and LCD Flash Simultaneously

The Issue:
When the HP Photosmart digital camera is placed on the dock without batteries, the AF assistance LED and LCD could blink at the same time. Explanation It seems that the super-capacitor on the camera senses the voltage supplied by either the AC adapter or batteries when they are inserted. This is more an annoyance rather than an actual failure on the device. The microcontroller (Dang) senses the voltage and sends a signal to the LCD and AF assistant LED. This is what some times is called a WAD (working as designed). If batteries are present or the super-capacitor is charged, the AC adapter will not trigger this behavior. This can be tried by inserting some batteries on the camera for 3 or 5 minutes, then remove them and place the camera on the dock. No blinking should be present.

Flashing Light

I have had a HP Photosmart 945 for a few years now. A few days ago was the first time I saw my camera experience the problem described above. I thought something is wrong with the on-bard logic.

Replacing my batteries (4x2300mAh NiMH AAs) with four other freshly charged batteries of the same kind didn't fix it. The camera's LCD kept flashing on and off for almost an hour until my family got tired of it and turned it off by removing the batteries.

I just replaced the rechargeable batteries with four regular alkaline batteries and now suddenly it works. Go figure.

The moral is that changing the batteries sometimes helps. When it works, it will get your camera going for a while. The problem, however, doesn't seem to be battery-related or I would have seen it a long time ago with smaller-capacity batteries like alkaline AAs. Something is very wrong with the camera itself, that much is clear.

Best-case scenario now is that I have an unreliable camera that can give out at any moment. For example today it died in mid-shot and almost spoiled a family event. For me the solution was "get a non-HP camera".

I hope this helps someone out there.

Red light flashes and LCD turns off and on

A quick test would be to purchase a set of Duracell Ultra Digital batteries and try them. They won?t last for very long; however, if they make the red light go away then you problem is either the batteries you are using or the charger. More often than not its going to be the batteries so we?ll start there: Check your batteries, you should be using Nickel metal hydride (Ni-ME) that are rated at 1450 (I use 2500) mAh or better. If the batteries are more than one year and you?ve used them a lot then its likely the batteries just aren?t holding a charge anymore. Purchase a new set or borrow a working set from a friend. Charge them in your charger and try in your camera, if the red LED goes away use the batteries till they need charging again. Charge them in your charger and if the red LED stays off then the batteries were the problem. If the red LED returns then try charging your batteries in someone else?s working NiME charger. Put them in your camera and if the red LED goes away then your charger is the fault.
