Issue: sudden display out. Reported to sony customer care on 29th and engineer mr.

Despite huge follow up with custmore care @ [protected] and local engineer the issue is not resolved and there is no concrete answer on resolution.
This is serious issue when it comes to sony brand name which is known for best customer services.
