I have an Insignia 42" model NS-42E470A13A with a strange problem that affects 1 channel only (channel 9.1 CBET-DT CBC Windsor).
On fIrmware 2.06 (which is what shipped with the TV), channel 9.1 works perfectly, however after changing to this channel the remote control completely locks up. Can't do anything at all on the remote. The only way to recover is to turn the TV OFF/ON.
So I tried updating the firmware to 2.08. With the 2.08 firmware, channel 9.1 comes in, but it "blinks" ON/OFF. When the channel is on, the audio and video are perfect (for about 2 seconds), then the screen blinks and goes completely black for about 2 seconds, then it repeats indefinitely.
Signal strength on channel 9.1 is very strong.
The TV is connected directly to an HD antenna installed on my roof via coax cable, no cable box.
All the other channels work great, no problems
This seems to me like a firmware problem, for some reason there is something in the 9.1 channel that is causing the TV to either lockup or blink.
Any ideas on how to resolve this?

Welcome to Community@ Insignia™!
You mentioned that the only way to get it to work is to turn off the TV. How are you able to turn it off? Using the buttons on the TV or do you have to unplug it? Is trhe signal strength showing very strong even when it flips to the blank screen?

With the 2.06 firmware, the only way to turn the TV off was to use the power button on the TV or pull the plug out of the 120V wall receptacle.
Now with the new 2.08 firmware when the screen "blinks", it is still possible to use the remote, but it is necessary to repeatedly press the button on the remote and eventually the TV will respond (to advance to the next channel for example). When the screen starts blinking, it seems like the TV gets stuck in a loop and can only respond to commands from the remote for a very brief instant.
The signal strength is always showing full strength, however when the screen flips to the blank screen, nothing is visible at all including the signal strength meter. However it does look like the backlighting is still ON.

This sounds like more than just a firmware issue. i'd like you to call in to our vcenter at 877-467-4289 so we can see about getting a service appointment scheduled to get the TV fixed. We are here from 7 AM-midnight everyday of the year.
