I am having an issue with my NS-PDP50HD-09 50 inch plasma HD TV. It shuts off on it's own at random times. I have narrowed it down to commercial breaks when watching a show. I know this sounds strange, but bear with me and i'll explain how I got to this point.
I've had the TV for about 3 years. Last week, it shut off randomly when watching cable. The only way to get it to turn back on was to unplug it and plug it back in. Within 15 - 30 minutes it would shut off again. I then tried some troubleshooting steps that include the following:
-use a different outlet on the surge protector
-use a different outlet in the same room
-move the tv into a different room
-place a fan on the TV (to make sure overheating wasn't a problem, plus, since I can just unplug it and plug it back in and the TV comes right on, I don't suspect there is an overheating issue.)
After moving the TV didn't help, I decided to try different inputs:
-a cable wire directly hooked up to the TV from the cable box makes no difference
-a cable wire coming from the wall (not hooked up to the cable box) makes no difference
-using the red, white and yellow connections for cable input makes no difference
-using HDMI cable for input makes no difference
I did notice that when using a video game console (wii on red,white, yellow input and PS3 on HDMI input) that the TV does not shut off, regardless of how long each system is being used. So it is definitely something to do specifically with watching cable.
So in my troubleshooting, I discovered that the TV was shutting off only when watching cable, no matter what input it was using. Going further, I then noticed that it would shut off when the program I was watching would go to a commercial break. But, it wouldn't do it all the time on the first commercial break. sometimes it would make it to the second or third commercial break, but as soon as that first commercial started, the TV would shut off.
This makes me wonder if there is some kind of issue with the programming format, or with the TV switching formats on the fly?. I think the TV is running in 480P (or 480I, either way I know it's 480 because the blue box says that when I turn the TV on).
So to summarize, the TV works ok when using a video game console, regardless of input. When watching cable, the tv will turn off during one of the first couple of commercial breaks, just as soon as the first commercial comes on in that break.
There is no warranty on the TV, and Insignia was no help when I called them. I haven't called best buy / geek squad as I wanted to do some research first before paying someone half of what the TV is worth to look at / fix it.
Thank you for any help or other troubleshooting measures anyone can provide.

I would first suggest resetting the TV to defaults by going to the Menu, then Setup, then select Reset Default and press Enter.
Also I would like to get a little more information from you if you do not mind:
Thanks for your detail information as it is always appreciated.

Thanks for the reply. MY cable provider is Mid Hudson Cable, and the cable box is a motorola DHC3416. Product specs from motorola can be found here:
I will try the reset when I get home today.

Due to the fact that the TV does not turn of when using your gaming consoles but it does when viewing cable, I would suggest contacting your cable company. I would recommend having them swap out your cable box with a different box to see if this is the root of the problem. If the issue still persists after changing out cable boxes please let me know so I can continue investigating this issue.

Hello Zac. Thanks for the reply. I don't feel the cable box is the issue though. As I said in my original post, the issue still existed when i just hooked the tv up to a wire that was not hooked up to the cable box. I move dthe tv into a different room and used the cable wire in there that does not use the cable box and still experienced the same result.

Due to the extensive troubleshooting that you have done and the fact that this issue only persists part of the time. I would suggest that you contact your local Geek Squad in order to have service setup and the TV is most likely in need of repairs.

Zac, with all due respect. Let's face it, these televisions are defective and a recall should be done. I too am having the same problem and from the looks of the board in this community many other people are having the same exact issue with their televisions. It is not a 'Cable" issue as you stated. IT IS A INSIGNIA DEFECTIVE TELEVISON. Issues. Why you and the rest of the people working at this company can't seem to see the obvious is beyond me. THEY NEED TO BE RECALLED IMMEDIATELY.

I am also having the same issue. This just started happening. I bought the TV September 2009. Just this week this started happeing to my 50" Plasma. I can have it on for 4 to 5 hours. It wil then cut off. I have to do the same thing as the others have done on this forum.
I unplug it and it works fine for a while and shuts off again. If it sits overnight it will again work for a while and then shut off.
