I am very disapointet, that SONY does not take responsibility for malfunctions due to bad upgrade.
After update from m8.727 to m8.728 the chanal shift is very slow.
I asked for solution, but got no answer but letting my TV repaired.
Now I looked for the latest upgrade - they might have develloped next version - m8.729? - but "No!" - the latest upgrade is now m8.727 - the former version! I would like to go back to that, but the systen does not alow that.
Why should I bye SONY nex time - this is too bad behavior!
Changing back the "latest version" must be aknowledge of a bad version m8.728 - or any other explanation?
