Tuner broken?

I have a Vizio VO320E LCD that is plugged directly into the wall via a coax. I was receiving my cable channels just fine before going to bed, woke up this morning, "no signal found". I went to my roommate who also has his LCD plugged directly into the wall and he has all channels. I have tried scanning for channels via antenna and cable and 0 are found. Does this mean my tuner is broken? Is this unusual for a set that is only 4 months old?
 
It could be a problem with your coax since you have your TV connected differently than your roomate's. The easiest way to rule this out would be to either connect your TV to your roommate's cable or vice versa. If it yields the same results (your TV tuner not work and your roomate's tuner working), then it's most likely your TV. Being 4 months old this should be covered under warranty unless you went refurb.
 
Sounds like a dumb question, but have you checked all the connections? Disconnect and re-connect? Make sure something didn't get broken physically on the TV and / or Wall. What about the splitter in the house / apartment do you have access to that?
 
Coax cables are _notorious_ for their unreliability. Definitely try changing cables, if it's possible.
 
OK, I have done the following.

My room:

Checked tightness of my coax cable in wall and TV - no channels
Checked my TV with my roommate's coax cable which works - no channels

Roommate's room (where his TV recieves channels):

Moved my TV into roommate's room, tried with my coax - no channels
Tried with my roommate's coax - no channels


Is it safe to say that there is something wrong with the set itself? I even tried resetting to factory settings before attempting a cable channel search... nadda. 🙁

 
Can you manually set it to a certain channel without even doing the channel search? If so, then set it to a channel that is verified as working on your roommate's TV.

You have both a QAM and NTSC tuner on your TV, both of which might be labeled as cable. Make sure that you're connecting it to the right connection and also make sure that it's set to the correct setting on the TV itself. I know these are no-brainer things, but those are often the things that get overlooked.

I cannot set to a channel manually, if I try it will say "no channel found". The only input options I have are cable or antenna and I have cable selected. Thankfully my HDMI port still works so I can entertain myself... This is really inconvenient!
 
I'm in touch with Vizio already, I guess I'll let you know how it goes here as a testament to however good/bad their response is. :laugh:
 
Just got off the phone with Vizio tech support. He spoke English and I was able to fully understand him, I told him what was wrong, he took my information down, and then scheduled an in home repair for 10/21/09 which is a week from today. Not too shabby IMO.
 
It's good to hear they are responsive. Often times we just hear the bad stuff but not enough of the good service, generating a skewed opinion.

The most interesting part about this isn't the response time or even the fluent English speaker, it is the fact that they are going to do an in-home repair / visit on a 32" TV. The warranty details specifically say over 32" if I remember right.
