Let me preface that I have the 46" version connected to the internet via Ethernet cable to a D-Link 825 wireless router. There is no new firmware for this router for over 2 years and I'm well aware of the D-Link 655 firmware fix. Since I don't have that router and I'm not using wireless, I was stumped.
While it may seem random, I've notice my set reboot every fourth day and within first 5 minute of powering on. Immediately after the reboot, I noticed if I go into the menu screen, the widgets and the internet contents disappear. They eventually will be reloaded but it's very annoying because widget settings are gone. It's a pain to set them back to my liking to have them reset again in four days.
I have contacted SONY about this issue and they made it sound like they never heard this issue at all. They eventually sent someone over to replace the "Mainboard" and I'm still have the same issue.
Ten days ago, on a whim I unplug my Ethernet cable from the TV and the problem seem to go away to this day. The only drawback obviously is I no longer have access to internet features unless I plug it back.
My question to everyone who is having this problem, do you guys happen to be using a D-Link 825 router? If so do you have this issue with Ethernet connection. I'm thinking of trying another router to to rule out this router as the source of the problem.
I have mine wired to a Linksys/Cisco 4200 router.
Yes, I noticed that after a reboot- that the widgets and internet content disappear for quite some time too.
So To summarize, I think this issue happens:
1) About every 3-5 power ons
2) When hooked up wired to ethernet
3) Within the first 5 minutes of turning on tv.
4) -- anything else? --
All three of those criteria seem to fit my scenarios and seem to fit what others are posting.
Seems like it's probably not hw-- as one poster had the main board replased and it didn't help. WDT typically means watchdog timer and host would typically refer to some main control firmware. It seems like there is some code somewhere trying to access something via the network (wired only?) that is hanging up. Could be router related. I THINK I have my tv set up with a static IP, but as I type this, if I don't I will to see if that resolves it.
It's hard to believe Sony has never heard of this happening since it looks like there are at least a few on this fourm who it is affecting. Did you get elevated to a higher lever tech, or just get an entry support person who was reading from a script?
