Hi, I had the same problem. One fine day I tried to switch ON the camera but it will never turn ON. Batteries OK and condition of switch OK too. Being a technical person, with the help of some colleagues, I decided to open the camera, assuming that sending it for repair would cost too much. We found a blown smd capacitor marked 4710d. We replaced it with a 47uF capacitor and also a blown link just adjacent to the capacitor. The link resoldered and the camera is working fine now. I must say that even though very complicated, the way this camera is assembled makes it easier to handle.

Assuming that the battery is OK, there are two switches that if not operating the camera will not power on - one for the SD card door and one for the battery door. Both must be closed for the camera to power on. Also, the main switch is a micro switch. You can see the battery door switch with the door open. Carefully check to make sure the little arm is closing. Sometimes if the battery door is worn it will it not close enough to close the switch - try pushing up the battery door all the way and see if it then turns on. You would have to remove the back cover to check the on/off switch, and to replace it you have to replace the entire back cover assembly. The other common cause is one of the bottom board screws coming loose and shorting the board. Most of these problem require professional repair, but if it is the battery door you can usually find them on eBay.
First, check that the camera switch is in the off (charging) position.
If this is OK, Check the battery output connections for voltage: use a multimeter.
To check the charger, put a load resistor across the output terminals (about 1000 ti 2000 ohms) and again, using a multimeter, check there is a charging voltage. Alternatively, if the camera operates OK with the charger attached and switched on the charger is OK, AND, the problem is then in the charging circuit from camera to battery. If the battery checks OK as in the beginning, then you will need a Sony repair man who needs to know all the results from your testing above.
I guess you can't switch the camera off when you are using it. But when you don't switch it off, the battery runs out.
After you charged the battery, what happened. Or next time, when it won't switch off, remove the battery, Then watch what happens after you reinstall the battery and try to switch it on.
If you can switch on the camera the switch is ok. If the camera starts immediately, after you inserted the battery, the switch is blocked. (makes full contact without you touching it). This is a real problem, and I think only can be repaired in the service centre. Please ask before what it will cost, because sometimes it is cheaper to buy a new camera.
hello sir .. does your batteries are charged already?? if your batteries are fully charged and your camera didn`t turn on, there`s a possibility that your camera has a problem. You can visit the store where you bought your camera and you can ask questions there why does your camera didn`t turn on whenever your batteries are ok .. :)
Hi Kris - If the camera worked before changing the batteries, but now it doesn't; check the batteries for proper insertion. If just one battery was installed incorrectly, the camera will not power up. Also, check the charge of the batteries. If even a single dead battery was included in the mix of new batteries, the camera will not power up either.
If all these conditions check out ok, the problem may be related to defective hardware (power switch, lens, etc.). When the camera is powered on, it goes through a quick self test. If any of these self tests fail, the camera shuts off immediately. This will often require that the camera be evaluated professionally. Hopefully, you'll find the problem is battery related.
hi, what type of batterys have you brought as most normal batterys you buy wont even switch the camera on you need hi power batterys such as lithium or even better go into a camera shop and they will have special high power bats, normal bats wont even switch mine on so give different batts a try
let me know how you get on or if you need fyrther assistance ok
