TV Repair Questions? Ask a TV Technician for Answers ASAP
I am sorry you are having trouble,how old is this set now please?
Where did you buy the set from
I see you have not had time to reply there are some checks that need to be carried out however the most common cause of this is failed back-lights, please conduct this test (when you have a chance)>>when the screen goes OFF ONLY>>
As a TEST/CHECK for me please press the MENU or the HOME button of the TVs OWN remote control (the one that came with the set)does the menu come up or not please? this is just a test exercise
