For now 10 years our BeoVision 7-40 worked fine. A few weeks ago during a television broadcast the display went dark and since then the TV itself is dead. The other equipment like the overture and beogram work fine despite the failure. I gave the BeoVision to the B&O dealer for repairing. They changed a lot of modules but without succsess.
It seems that the backlight could be the broken part and therefore the TV is a total loss. That is the statement of the B&O dealer!
Could this be true? Does anybody know how to rapair the TV or where do I have to look for the failure?
