And finally my HX750 started showing this issue. Mine was bought in 2012. Today evening suddenly out of the blue, the TV started turning off and on for like 3 times and then turned off permanently and red light started blinking 8 times. I tried doing the same power reset and factory reset but no luck. Then i decided to remove internet connection (mine i a wired connection) and tried doing a factory reset. It worked ok, but the moment i connect internet and try to refresh internet contents the problem starts again. This happens both for wired and wireless connections.
My firmware is upto date (PKG2.120AAA), i even tried downloading the firware into a USB stick and update, but it gave me a message saying 'no newer version of the tv software was found'.
Is this something i can fix on my own or do i need to contact sony or call a service man?
Any help will be appreciated.
I was just coming to post the exact same thing!! I have the EXACT SAME SYMPTOMS. (including it working with Ethernet wire removed, but I haven't tried with wifi configured).
I got my 55HX750 March 3, 2013 with the 5yr Sony Protection plan, so I called Sony last night.
The rep I spoke with suggested its an issue with the internet connection. He had me try resetting, factory resetting, unplug the Ethernet cable, reboot my router, etc. several times. Without fail, as soon as I connected the network wire, the TV started resetting.
Searching online, I found .AU sites talking about this issue a few years ago, suggesting its a corrupt EPG data (See -> http://forums.whirlpool.net.au/archive/2115391
). It was supposedly fixed in firmware update back then. Not sure how it applies to us. There are also some trouble shooting steps in there that appear to be related to the main board needing to be replaced.
Sony support is going to call me back later today. Since the problem persists (at least when connected to the internet), they are likely going to replace my TV as he didn't think repair parts are still available for the HX750. I do not know yet what they will offer/give me as a replacement. He mentioned possibly a 2014 model, if a 55 isn't available they might give me a 60-65", etc. but didn't mention possible models.
I don't know what is consider equivalent to this TV, or what has comparable picture quality viewing both SD and HD. From what I'm reading and reviewing, I'm not sure what a suitable replacement will be.
EDIT: After running for about two hours yesterday morning (without Wifi, and with ethernet wire unplugged) and the TV not having any issues, I decided to try Wifi. After configuring Wifi, the TV kept on going, no restarts, no flashing LED. I began to watch a movie via Amazon Prime, again no issues. After about 4 hours of the TV being on and connected via Wifi, I decided to again connect the ethernet cable and configure the TV for wired ethernet. Again, no reboot issues. We watched about two hours more, and it was fine. Solid. Working normally.
It really makes me wonder about that "corrupt EPG data" in the .AU thread...
When the Sony Rep called me last night, I explained the situation. I asked if was alright to close the case, and re-open it later should the issue start again. He said that is fine. The case number I have will stay in my file. And my protection plan is of course still valid for a few more years.
