Thanks to all of you,

The camera has been taken apart and, indeed, there is a battery of a

size of about half an inch, the battery was soldered onto the flex

with two ss contact.

The voltage of the battery is 3.44 V, is this the correct voltage or

it is too low?

If the battery is not the cause of my problem, then what could cause

the LCD goes to blank while the camera is switched off?

Another question is that is there a reset mechanism that would reset

the electronics to factor default state?

Thanks again!

1). Is there a back-up lithium battery in Canon T70?

2). How to check/find/replace this battery, if there is one?
