Question about Televison & Video

Open Question

Sony Bravia LCD TV Model KDL40W550 When the TV is on the screen will suddenly go blank (Black) for a couple of seconds and then the picture will resume as if nothing had happened. This happens whether we are watching analogue or digital channels or replaying an analogue DVD. It is as if the TV loses the signal for this time. Can you offer any solutions?

SOURCE: We lose audio on our Sony BRAVIA KDL-52W4100

This problem appears to be an issue with numerous Sony Bravia owners of the same model. Although still seeking a soulution, it would appear that our cable provider (Verizon) has replaced all of their components and the Geek Squad from Best Buy where we purchased the unit, points the finger at Verizon. None of our other Fios-equipped TV's exhibit this problem so I am glad we bought the service plan with the TV and will continue to seek a remedy.

This is a characteristic of the dynamic backlight used on this set.Turn off the dynamic contrast in the customer menu this should solve your problem.

Hello Robert, the picture tube on your TV set is exausted. Please contact your nearest Authorized Sony Service for further help/advice. After all, Sony is a good choice. The next TV set you buy could be one of Sony-s Bravia LCD. Kind regards, Arpad
