After fully charging batt on my new hd170 and turning on...all i get is the HD170 logo screen, it will not go to the live preview screen and i cannot turn off without taking batt out...please advise

Sounds like one or both of the batteries has a high internal resistance. Bad batteries, perhaps? Have you LOAD tested or tested for internal resistance? Could be why charger is shutting off so soon.
Voltage isn't the only test for these types of batteries.

I had the exact same problem. I took the camera apart, adjusted the height of the gold plated spring connectors inside the SD card slot, and re-flowed all of the SD card slot solder joints. The camera is now working good as new... Good Luck!

Vpad 7 frost at first n then now wont turn on? I need help to turn it on? Dont know whats goin on?

No, it should immediately start if you have the battery connected properly. Are you sure this new battery is fully charged? It may just need charging. If the battery is fully charged and connected tightly then you have another problem.

What kind of batteries? New rechargeable batteries are supplied only partially charged. You need to charge them fully before use.

ur new batt probly was not charged -the alternator/regulator is failin -inspec whole electrical system for bad wires,contacts etc--things wear with age--library in 629 has many repair guides

no if you have a good batt you don't need alt the alt charges batt after you start the car

Make sure that you are installing a fresh/ full charge battery
Here are the steps:
1. Make sure you will install a new or fully charged battery/batteries into your camera.
2. Clean the battery contacts.
a. Remove the battery/batteries and the memory card from your camera, then wipe the battery contacts with a soft, clean cloth.
b. Reinstall the battery/batteries into your camera
3. Without the memory card,turn on your camera.
4. Pls test with an alt. batt.
If you do not have access to a dif. battery.
Pls. take the batt out of the camera. Insert the charger into the unit from the main socket and turn the camera on. If the camera works you will need to replace the batt. If not you will need to order a No power repair.

Make sure all connections at alternator are attached. On some, the regulator is inside the computer and if bad, requires computer change.
