HD TV blacks out. Help I yelped!

[UncleMo]

While playing MK II online, the only finishing move I saw was on my TV. That's right it blacked out on me. It went out, then I freaked, I switched from HDMI1 mode to TV mode, and it came back on. So I kept paying and it did it again. I jumped out of the match dismayed, talked to my wife about it as she saw it too, and then I shut the gaming console off and tried to watch TV to see if it is a console related issue, an HDMI1 related issue, or if I could catch it happening on the TV mode as well. Sure enough, it happened again a minute later when watching TV.

The only new thing that has happend lately is that I've added a dual band wireless N router, but I seriously doubt it is that. Any suggestions that don't include stabbing myself with a plastic spork?

Notes: TV was purchased at Wal-mart in the fall, it is a vizio, and it is model V0370M.

I had that happened once, it was the powe cable was not 100% in on the back of the tv, once I pushed it in hard it quit....have u checked that?

Did the picture just black out? Can you hear the sound?

Or did the TV completely turn off?

I think, as i understand his post, his tv went off and came back on. That's exactly what kept happening to me on my set at random. once I reseated the power cord that plugs into the back of the tv firmly it quit happening. Of course it's also possible his cord plugging into the wall is 95% in and just needs reseated as well.

I don't think it'd be his HD cord or the tv wouldn't have turned off and back on but went to a "NO SIGNAL" picture.

Ok, I was a test it out last night for an hour. Turns out, very slightly was my PS3 plug unplugged, therefore it would only black out for a second. Which, now that I think about it, does not explain why it would black out in TV mode. I did have all of the plugs plugged in firmly before testing everything out. I tested the PS3 out for an hour with no problems, and in TV mode I tested it out for 2 hours with no problems.

Thanks for the answers (and questions). For now, let's see how this goes, maybe it wont' happen again. Thanks again.

Ok, so what do I do if this happens again and it isn't the cords? Take the TV back? The TV will be on in HDMI or TV mode, and I can hear the sound but see no picture. This seems to only happen once a month.

This time, I was in HDMI mode when it blacked out. I unplugged the HDMI cord so the TV would then say "no signal", I then plugged that cord back into the back of the PS3, and then the picture would come back, only to fade out 10 seconds later.

If I switched it to TV mode, it did the same thing. Now, it isn't doing it right now but I'm concerned I have a TV that may need to be returned before the warranty is up...assuming there is a warranty.
