Hello, first post - Received a 67A750 12/30 around 8:30pm. It was cold outside so I waited 2 hrs before plugging in and turning it on. I was going through the menu options and the screen froze. I was not able to use the remote or the side buttons for anything - had to unplug the TV.
After about 3 hrs of having the TV freeze randomly and none of the remote buttons working, could not turn off the TV except by pulling the power, I left it unplugged all night. New Years Eve, I turned on the TV and went through the menu options and everything seemed Ok until I tried to switch to alt source, (to PS3 from Cable box both are connected via HDMI to Yamaha receiver), then the TV went black and seemed to turn off/on, could not get the pic back without unplugging TV.
To sum up it seems that the TV will freeze up randomly when going through menu and sometimes will freeze when switching source on the receiver. I have been through the forum and do not see anyone having the TV freeze while using the menu.
The firmware reads: Module:T-AQMAUSC-1005.3, Date 2008-04-17, MICOM: T-AQMAUSM-1000 EDID Success, RFS: T-AQMAUSC-20080416
It would seem that the firmware was update from 1000 to 1005.3...manufacture date is Sept/2008.
