A matter of broken electric electric capacitors inside your TV.

Solution:
- Open backplate (loads 'o screws and ruins your warranty)
- Remove the connectors from the center circuit board
- Remove the circuit board via 4 screws located on the side
- Remove plastic on the back of center circuit board
- Remove cooling plates of circuit board
- Look for bulging capacitors
- Solder these out
- Go to local radio shack, take the capacitors (and spend about 5$)
- Resolder new capacitors
- reinstall circuit board
- Hook everything up and close the back plate

Voila! (at least, this worked for me)

This is your mainboard needing replaced! Simple as that!

The main sends the pson signal and without it...you have a dead tv.


Please rate if this helped :)

Pictures has lines and blotches. The display has them and when the pictures are taken they look like the display. If you view photos taken previously they are ok, so I figure the LCD is ok.


This sounds like it might be a defective CCD imager. If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check this link for more info.

Black screen


OK, this might sound stupid, but I had the same problem with a similar camera and I had accidentally pushed the Display button. I was about to give my camera up for dead. Try pushing it (the little button on the bottom back that says Disp on it). Does that bring your image back? If not let me know and I'll research further.

Blank black screen for my canon powershot S1 IS digital camera


This is a common problem with S1 IS and it is caused by faulty CCD sensor. Note that you can playback captured images without any problem but in capture mode all you get is blank screen. Will have to go to Canon but note that Canon repairs these models free of charge when it is the CCD sensor that stops working.

Powershot S1 Digital Camera: Flash won't fire


Make sure the camera is not in Document mode . Document takes a picture with added contrast so text stands out. Make sure the camera is not set to Infinity focus . When you select Infinity Focus, the camera automatically turns off the flash and auto focus so you get sharp, clear pictures. Make sure the camera is set to Fill, Auto, or Red Eye flash. See your camera manual for details about setting the flash.
