I decided to do the software update this morning and when the tv was turned back on it would show the picture for maybe 5 seconds then go off for two to three minutes the repeat the problem. I chatted with Sony live chat and of course rebooted the tv which did not work. He advised to do a factory reset which did not work either. I was told he had exhausted all his resources trying to find a fix and would bump it up a level but it would be within two business days. Has anyone else ever had this problem with their Sony TV and a software download failure?
