Just when I decided to keep my 46HX909, the issue of sudden reboots and on-screen menu lagging has re-emerged. Specifically, when I try to access and navigate the on-screen menus, they take forever to respond, then nothing happens, even though I'm pushing the arrow buttons and the green light on the TV is blinking. Then, without warning, even after I've stopped pushing the buttons on the remote, the menus zip across the screen.
This behavior, like the sudden reboots, occurred when I first got the TV a couple of months ago, and then stopped happening. I figured a firmware update fixed the issue. Still, to be safe, I had an authorized Sony technician take a look at the TV. They, in turn, contacted Sony, who recommended replacing the main board and the remote receiver board. Since the problem had subsided, I elected, at that time, to hold off on the repairs.
For the last month or so the issues did not happen. I'm not sure if this is related or not, but during this time, my TV wasn't hooked up to my network (I returned the both the over-priced Sony USB dongle and moved my Apple AirPort express, which provides access to the wireless network via an ethernet cable from the express to the TV, to my office.). A few days ago I re-connected the TV to the network via the AirPort express, reconnected the co-ax cable to the back of the TV (even though I guess it's not necessary), and it seemed everything was okay at first. Overnight the TV did a firmware update from 105 to 107. I refreshed my web content and then, while customizing my input labels, I lost the use of the home button and then the TV rebooted itself. It did this twice.
Then, yesterday, I discovered that there was a HUGE lag in the on-screen menus. I tried unplugging the TV. I tried disconnecting the network cable. I tried disconnecting the co-ax cable. I unplugged everything accept the HDMI cable from the cable box to the TV. Still, the menus lagged like crazy.
I contacted Fry's, and they allowed me to return and re-purchase the TV, giving me a new 30 day window to try to resolve the issue. HOWEVER, they warned me that if Sony attempts to repair the TV, THEY WILL NOT ALLOW ME TO RETURN IT - EVEN WITHIN THE 30 DAY PERIOD. I asked, out of curiosity, how they would know, and they said that their system would be updated to alert them to the unit having been serviced. This was the manager of the returns department, so perhaps it's true.
So here are my questions:
1. Could the firmware update or web content update be causing these issues? Like I said, the menu lag continued to occur even after disconnecting the TV from the network, but by then the firmware and content updates had already been loaded.
2. Could my Apple AirPort Extreme router be an issue?
3. I paid $949 for this TV, new. I HATE the idea of returning it. Is it worth keeping and having the repairs done, forfeiting the ability to get my money back, with no assurance that the problems will be resolved. Even the Sony repair guy said he had no idea if replacing those two boards would resolve the issues?
4. Can Fry's ACTUALLY tell if an item being returned had been repaired? Could they possibly have a link to Sony? Seems far-fetched, but the manager was pretty adamant about that point.
I'd GREATLY appreciate any and all advice!
UPDATE: Took the TV out of it's box and hooked it up again. Just power and HDMI to cable box. Still got severe menu lag. Then, accessed the "initial setup" and went through all the steps, skipping network setup. This seems to have cleared up the menu lag - at least for now. I then connected a new Sony Wireless USB dongle, set up the network, and re-downloaded web content. Still no menu lag. Again, I didn't do a factory reset - I just walked through the initial setup and that seems to have had a positive effect on the menu lag.
I contact Sony Tier 2 tech support and got the procedure for a factory reset, just in case (the initial setup did not clear any of my picture settings, input labels, network name and password, etc.). I will hold off on performing a factory reset until the lag or sudden reboots re-appear. The technician I spoke to said that sometimes, when a firmware update is done, files can remain in memory and that perhaps running through the setup flushed the memory? Does this make any sense? Has anyone else experienced this kind of memory "bottle-neck" affecting the on-screen menus or causing a brief reboot of the TV? Could I have a bad memory SIM? Is the memory stored on the main board or is it housed separately?
Again, many, many thanks.
