I am experimenting with Insignia's and there is a feature whereby if a signal is not detected the TV will switch to standby mode (in about 10 - 15 minutes). It's documented as a tiny "note" in the manual under "Understanding the basics - Turning TV on or off"
I don't know if the TV resumes when the signal is restored or if you need to power on manually.
You are probably experiencing a glitch with the signal or the TV thinking the signal is not there. Are you watching a clear picture when this happens? I would first check to see if the signal is too weak (like using a signal booster). If that is not the case, it's probably the TV acting up.
I hope this helps.

A common fault with this model is bad capacitors in the power supply, Remove the back from your tv and look at the power supply for bulged / swollon capacitors on top, they may even leak a brown like substance and should have a value of around 1000uf 10v
Change these where possible with the same uf but higher voltage lets say 1000uf 25/35v
Hope this helps
Please rate my reply++++

this could be a problem with the power supply in the tv, it is common and repair kits are available quite cheaply if you have good
Usually this is caused by capacitors that have dried up and split, you can normally tell as the capacitors are bulging on the pcb, you can get them in a kit as I said eBay sometimes do them or you can buy them indivually from a good electronics components supplier, make sure you get the correct values for each!! marked on the side of the capacitors in xx/v V, xxx/x uF and 105oC.
The picture below shows the type of theing that happens, the brown ones are bulging/split on the top whereas the black one is fine.
High Voltages can exist in these sets, never attempt anything while plugged in and
if in doubt do not attempt it yourself and seek the advice of a qualified TV Technician.
