Vivitar 3755 Digital Camera Problem-

Check if they are the ones that fit to this exact camera. Sometimes cameras don't "read" random batteries and they have to be the one's that the manufacturer says (check the manual).

Did you check if the batteries are inserted correct? + to + and - to -
Also it could be you have the wrong batteries.
Depending of what you use, always be sure all batteries are the same, charged and suited for your camera. Most of the time even new Ni-CD rechargeable batteries won't work, because the voltage is to low, according to Ni-MH or alkaline batteries. Checking the voltage of every cell with a multimeter could tell you for sure the batteries are good. Voltage should be jus above the voltage printed on the battery when measured.
Never use manganese (Zinc-Carbon) batteries, because they don't have enough capacity to let a camera work correct.

Check the timer configuration .

If the battery is good and if you have triggered the power ON button the camera must come to power. If not remove battery and check the voltage, if low charge till the voltage shows up .
If the camera still does not come on then you have a problem in hand and it is best to get an opinion before you try to open the camera.

As its brand new, I'd go straight back to the shop with it. You've got an automatic 1 year guarantee with all electrical products bought in the UK

I bought a replacement battery for my Vivtar 8300s today at Batteries Plus. If there isn't one near you, go to their website: www.batteriesplus.com Cost was $17.95; they may have to order it from their supplier in New York, but the battery is in their product list. It's Empire model BLI-315.

I have a ViviCam 8400 and have the same problem UNLESS I buy Duracell Power Pix or Energizer Titanium batteries. These cost more than the regular grade AA batteries, but when I used brand new regular batteries, the camera would turn on for 2 seconds then turn right off. Titanium or Power Pix batteries make the camera work fine. And, because they are made for digital media, they do allow you to use the camera for longer periods of time.
