Aiptek IS-DV newly fully-charged battery, emptied camera memory card and memory stick, but when the camera is on and try to take picture, "memory full" always displays on the screen and it doesn't click. why?

The only maybe on this is the joystick is out of alignment with the touch points. You will have to take the camera partially apart to investigate if this is the case.

Are you sure your camera is actually switched to use the card or it's internal memory. It's possible your card has become corrupted and only has enough room for 1 picture. The card can be reformatted but use the camera to do it, not your computer. When you format using the camera make doubly sure you have either external power applied or a good set of fully charged batteries on board.

If the power fails during a reformat you can ruin the card for good. Also, if you have a spare card which most people do, give it a try to see if it works OK. Unfortunately some cards don't last forever and can eventually die.

Your problem has a very simple fix. The camera which you have is not compatible with SDHC cards. It will only work with regular SD cards.

Your camera is incompatible with the later SDHC specification at the basic hardware level and so cannot format the card which you have purchased.

Note that SD cards are available up to and including 4GB and SDHC start at 4GB so you're not the only person to have made this mistake. In practice there are very few devices designed to use regular SD cards which will work correctly with 4GB SD; Aiptek only designed and tested the IS-DV up to 1GB SD capacity (see page 48 of the user manual), so this is the effective limit to the largest capacity memory card which you can use, if you try larger capacity cards they will either not work at all or will make the camera operations sluggish and you also risk damaging the card itself so that it will no longer correctly format. Aiptek never released any firmware updates to improve the SD compatibility on your camera.

I'm sorry not to be able to offer any way to use your current SDHC card but at least I may have prevented you making another purchasing mistake. Please return the favour by rating my answer.

The SDHC (32GB) card is not supported by that model. The IS-DV has 16MB internal memory and supports up to 1 GB SD card.

Return 32GB card ... very expensive...

Hope this helps!

Mine does this if the battery is not charged. Make sure the battery is installed with the contacts lined up (my daughter is a pro at putting the battery in upside down, and it doesn't connect to anything that way!) and charge it up overnight.

If it's still giving you trouble the next day, post back and we'll try something else.

All right if you have the same problem that i had what you need to do is take the battery out the take the memory card out the put the battery back in then try and turn it on if it works then put the memory card back in and it should be fixed

Exactly the same thing happend to me with my brand-new Aiptek. Turns out it was the no-name brand SD card that I got from China which destroyed it. Aiptek was kind enough to replace it for free since it was under warranty. Aiptek's caution: Stick to brands like SanDisk, Dane-Elec, Kingston, Transcend or PNY. Purchase from resellers like Target, Best Buy, Newegg.com or Amazon.com. Avoid MINI & MACRO style cards. NO Sandisk Ultra II or Extreme III, class 6. AVOID Hi-SPEED!

You dn't need one. The 5700 IS-DV is plug&play. For details see

i have the same problem,,
the battery its full and the camera no power on,,
help us!!!!!!!!!!!!!!

Seems like its time to flush the contents of the memory card of camcorder to a computer.
There's a limited amount of memory in every memory card. After constant recording, the memory  gets full and the recorded stuff needs to be either deleted or flushed (uploaded to a computer) to make room for newly recorded stuff.

Unless you have a blank memory card, your problem should be solved by the above mentioned idea.
