I have the same Sony KV 35545...with the same problem. This black out problem only happens when it rains or is very humid...turn the ac or dehumidifier on and it will always work...no damp weather of humity, it will always work. My friend, a TV tech at ABC told me, there is a protective turn off when it gets too humid...it is a shut off internal switch which activates based on the humidity. Sony should fix this issue with all our tv's. This is not a voltage regulator problem...that is the wrong diagnosis. We should go after Sony on this issue. Joe D
