When i chage the option of oFF to CAMERA nothing turns on and when I change the option OFF to VCR the screen just show strange symbol and SP and it does not work

Just so you know, your camera model was included in the list for what we call the "ccd program". this program has ran for 5 years and unfortunately ended march this year. sony gave free repairs for cameras and camcorders affected by the defective ccd imaging sensor before the said date. issue with the camera shows a black or distorted screen in camera mode. but the you should still be able to see the indicators on the screen. when switch to vcr you should be able to play back previous recordings that you made. better to really make sure its a ccd issue, play a tape that you're sure contains a movie recording and play it, then set it to camera mode and see if you get just a black screen. if you try recording using a tape, you may see nothing but should hear the audio part. if this is what's happening we can be sure it's a ccd issue. if your camcorder just won't turn on in camera mode, maybe the power switch turned defective or it can be other parts of the unit that stopped working.if this is the case, then of course, your unit may require service to address the problem.hope this info helps.thanks:)
