You need to check the back light is still on when the screen is blank (check through the back).

If the back light is on, need to change the Powwer Board.

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

Turn on camera but the lcd sceen is black


I tried all the solutions offered on the net and none worked except one. It simply said "hit the camera with the palm of your hand" (when it is on) and the screen will return. I thought, well I have nothing to lose and so I hit it on the side and sure enough the LCD is again working !!! Contacted Canon prior to this and they had no idea but suggested I send it in to be repaired at a cose of $163.50 Australian. Pleasant staff they have, but no help in solving what looks like a common problem of Canon cameras. I will have second thoughts purchasing Canon from here on in.

Picture goes blank


Consider re-initializing the machine (Pg. 55 in the manual). The only drawback to this approach is that you'll lose all preset settings.
