Answer: 
According to our records, all of our televisions currently utilize a matte screen to minimize any glare while viewing. The normal viewing angle averages about 170 degrees.

Firmware update for 37LH40 ?

After 2 years of perfect operation, in the past year, we are now experiencing intermittent momentary picture freezing while sound continues fine. I understand there's a FW update for the Sept 2009 build? Can you provide some help to fix this problem?

I apologize, but we do not have a listing of any firmware updates available for this LCD television that are available for installation without assistance. If such an update is available, then it will require installation by a certified technician.

Answers

Answer: 
We appreciate your interest in this television. This unit is not designed to be able to reorder the channels in the manner you have suggested. The channels of each separate tuning band will remain separate. The only way to quickly switch between each tuning band is to enter a specific channel number.

Answer: 
I apologize, but no; this television and its connections are not designed to send an audio signal through multiple connections. The OPTICAL Digital Audio Output jack is only designed to send the signal to a single connection, to a digital home theater receiver.

If you want the perfect balance of technology and features, look no further—you’ve found it.
