SOURCE: sleep timer is shutting of
Hi,
To start with, this is an internal problem as you have observed. However, before we go ahead and diagnose the fault, kindly provide few details :-
1. How could you recognize that it is the sleep timer that is causing the TV to be shut off? There could be many components which could cause the same. Did you see any message or display?
2. Do you have any electronics repair experience?
3. How old is the unit?
4. Do you want to have an estimate of repair or wanted to fix this yourself by repairing the TV?
Let me know,so that we could proceed.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
