Our Insignia NS-30HTV picture is sort of hour-glass shaped on the edges. About 2-3 inches on each side of the picture is missing. How do you fix?


In my experience, this indicative of TV tube failure. However, just to be sure, try resetting the TV to factory defaults by entering the onscreen menus, select Picture, then reset. Also, power-cycle your TV (turn it off and unplug for several minutes). More details can be found in the owner's manual. If these steps don't resolve the display issue, you may call 1-888-237-8289 in the U.S. or 1-866-237-8289 in Canada to schedule in-home service.

Sounds like power supply problem (either poor connections or bad capacitors).sometimes they look deformed or you have to check them with an incircuit capacitor tester.

No picture


Try a "hard restart". which simply means unplugging the power cord of the TV, and replugging it after 4 hours have passed. This technique reprograms the electronics, to a certain extent.
You can also visit the manufacturer's website or call their tollfree number for problem solving info.
Hope these suggestions help you out.

I fixed the problem with the "no power on, low clicking noise". The NPN transistor (2SC5931) was shorted. This transistor controls the horizontal hold. The shorting caused the power supply to overload and restart, then recycle. This was the cause of the clicking noise. Unfortunately this transistor was over $50, most likely due to the extinction of CRT's. I did find a replacement transistor 2SC5552, which only cost $2 (but I was able to get it in Mexico). The location of the transistor is located on the left side of the TV (looking from the back). Directly in front of it is the high voltage transformer which powers the CRT (should have a thick red wire). The transistor is attached to a large aluminum heatsink. To remove the transistor you will have to remove the entire electronics assembly to you can easily get to the underside. This was the solution for my TV, but there could be other components damaged.

Without opening the set or having a tech look at it, it is impossible to tell. Maybe only a fuse blew? Good Luck
