Independently, out of the blue, it has begun to start scrolling through the channels, similar to a scan, however without any prompting from us. I try to turn it via the remote and although you can see the light flicker, it won't respond. It has once or twice turned off, only to turn back on by itself!
It's installed in a built-in cabinet in our kitchen and we're unable to reach the TV controls that are underneath the TV itself (that was well thought-out!) to be able to turn it off that way, also because of that mounting we can't pull the plug.

Re: Our LG 37LB1DA is scrolling through channels
I have seen problems similar to yours in the past. Several causes can
make the channels change by themselves. Some corrosion on the main
board near the channel up/down switches for one. The next common cause
is that the EPROM may be failing or a fault with the main control
processor. A good test to see if the EPROM is having a problem is to
program in all the channels off the cable and then unplug the TV over
night and then plug back in the see if any channels are missing.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

You probably need to SCAN the channels. Connect the signal source to the tv. Either cable or Antenna. Enter the menu mode on the tv. You can do through the remote.
Scroll down to the signal source. Select the signal source you have connected to the back of set.
Scroll to SCAN in the menu. SCAN in the channels. Exit menu mode.
You can now watch available channels.
With remote, hit MENU, (use up/down arrows) & scroll to SETUP. Hit ENTER & scroll to TV. Hit ENTER & scroll to AUTO CHANNEL SEARCH. Hit ENTER & scroll to CABLE. Hit ENTER & scroll to AUTO. Hit ENTER, wait as it scans (about 5 min). Your done.
Try this as your model is basically the same as mine.
Push Menu on your remote. Then a small screen comes up. Using your left right arrows move left to set up. Scroll down to tuner mode and again using left right arrows, there are 4 setting you can choose. Once the setting you choose is showing then scroll up to Channel Searching and hit OK on your remote. This will scan all the channels Digital and Analog.
Depending on which of the 4 setting you picked on TUNER MODE you may have to do this again in the next mode to see which will get the most channels on your TV.
