SONY 32FQ75 TV is due to be returned Friday. It has been away for three weeks and is being returned as engineers are unable to find any fault, and the service menu says no error has occurred - yet it has ! Tv goes bright blue and then into standby and LED flashes 5 times. Engineer says Sony are unable to confirm what the 5 flashes mean and they have had the set on every day from 9-5 for 3 weeks and no probs - yet I have explained that the problem generally happens over a prolonged viewing period i.e. The weekend. Engineer not prpared to test overnight as not insured!! This has happened on three occasions for me and just KNOW that when I get the set back it will go off again. Could it be anything I am doing - I have an amp,dvd and video all connected but everything else works, no faults in power supply etc. Where do I stand now, I know the TV is faulty yet engineer says nothing they can do. I have wrote to Sony and Hi-Spek (supplier) and await their answers but in the meantime has anybody got any ideas (gaurantee runs out in 3 weeks) . .
