This particular model has a 60Hz refresh rate. At this point there are no broadcasts or video sources outside of special labs that can generate enough data to produce a refresh rate of 120Hz. Expect this to become available in a year or so. Please realize that the human eye can not see changes faster than about 30 frames per second. The current standard refresh rate of 60Hz is twice that. The only change you could see (unlikely) would be a slightly smoother flow for fast moving scenes. Typical movement on the screen will not likely see a difference.

SOURCE: LCD 32 inch Auto Scan issue
I have experienced exactly the same issue on two Westinghouse sets. Try turning the set off when it reaches 83%. When I turn mine off and back on, it has saved the channels -- at least the ones it had found before it got hung up.

Found that TV started switching off by itself. Would try to come on..green light blinked for 2-3 seconds, tv came on (with picture and sound) for 1 or 2 seconds and then it would turn itself off. Found that the issue is with one channel only. If you are facing this issue....try quickly changing the channel the moment it comes on. You can do it either with remote or with the TV buttons directly. also in the same logic, if this is still happening, try changing the source to another (rgb-pc, av1, av2 etc). Basically change it from whatever input it is on currently, if changing the channels does not work. My symptom was that the tv made a loud 'TIK' 'TAK' sound which is louder than normal.

This is a very common problem with these models.
The problem is very likely a fuse that has blown, if the following is true:
No Video on any input BUT HDMI and
No Audio at all.
Purchase a fuse, these are freaking tiny from digitalkey.com or mouser.com F1455ct-nd
Pull the back off of your unit
Pull the cover off of the PCB housing. It is the box that contains the hook ups including the cable tuner.
The silver box that you screw the cable to is where you begin to look for this fuse.
About two inches behind this silver box is some numbers printed on the board 7c32 and partially obscured will be 1c33
Using a big magnifier look next to the numbers listed above, you should see a tiny rectangle fuse with an F on it.
This F fuse is a 500ma fuse that is too small for the load
The fuse listed above will have a G on it. It is a 750ma fuse.
Call the repair shops in your area, tell them that you know the problem, have the part and you want to know how much the bench time and labor will be to repair your unit.
