a77 issues, please help

[mfriesenm]

hello,

I have a one year old a77 in what I believe to be a good condition. While I was watching pictures I took, I noticed the battery was running low (3%). I plugged it in so that I could continue viewing my pictures. The moment I did so the lcd turned dark and I was unable to turn the camera back on again.

Anyone has had this happen before? any ideas of how to fix this?

Thanks in advance!

I looked this up. apparantly there is no physical outside difference between a power cable with data and a simple data cable.
The power goes through pin 1 and pin 5 is a ground. I looked at the the a77 and it does posses 5 pins.
But you do bring up a good point. If trying to charge the device using a wall charger can fry the camera, why not cut the link (even internally). or why not use a different connector that is always data only? (Such as the cable connection used for printers.

That is interesting. Maybe that cable that melted the usb port on my NEX-3 was defective.

The USB data only uses 2 pins, two of the pins are ground and one is +ve power. If the camera does not accept power, there is nothing inside the camera to connect that pin to, so it could not have fried.

I feel your pain. You might have fried it, but then it might come back - use a freshly charged battery - a different one than the one that ran low in the camera.

This whole incident is sort of unfortunate because if you had a spare battery you wound have had the problem. I keep spare Sony OEM and a surprisingly good Wasabi battery always charged as a standby. Generally I never want to connect the camera to a cabled power source, too risky unless the setup is exactly according to the manual with the correct cables, accessories and devices.
