This is my cameras problem- If the LCD screen on your DSC-M1 is solid black, or pink and purple running paint when you try to take a picture, you can see the menus perfectly fine & can still play back old images, You have a defective CCD sensor. Has anyone fixed this and does anyone have a repair manual?
You can download the Level 2 Service Manual from here. Also, make sure that the you recheck the flexible ribbon cable of the CCD imager. It does need to be plugged securely in main board connector. The part is available at places like this. Or even ebay.com but it all depends on your geographical location. a good Google search will of course help you with that. Good Luck
