There should be buttons on the cabinet to control the TV. Are the buttons on the cabinet not working?

Toshiba 40rv525r screen says NOT AVAILABLE

I've had the same issue! This is caused by the control panel telling the TV what to do - does it change channels on its own, too, or turn off or on on its own?

What you need to do (if you've not already done it) is lock the control panel out, which you can do under the LOCK menu.

What may help is running the factory reset on page 54.

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.

To fix the problem, try turning off the TV and unplugging it from the outlet. Once unplugged, push the power button and hold it down for 1 minute. Then turn the TV back on and rescan for channels.

If the problem persists, contact LG customer service immediately as there is a problem with the memory card. The device is unable to retain scanned channels for immediate feedback.

All LG LCD automatically comes with a 1 year manufacturing warranty. You would have to provide proof of purchase to show when it was purchased. Hope this helps. The Guru
