    I got exactly the same problem. It may not be the power supply. It may be the software or the computer hardware. Please help.

I had exactly the same problem. I return my first one. After a couple of months, it happened to my second one. It could be a software /computer issue. It only happened after a channel, 7 or SBS missing by itself.

Could it be that the mains supply in your area is not steady? It might be dropping unacceptably low for the TV; if you can, get an electrician to at least eliminate this possibility. Rapid fluctuations can occur if there are large inductive loads sharing your line - for instance industrial motors which start and stop with a lot of voltage spikes. These can travel quite a distance, you'd be surprised.

37lg50 lcd tv turning on by itself and channel surfing on its own

Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

We purchased a Vizio 42"

This is more of a provider problem. Report the signal problems to the service you subscribe to for tv.

42 in LG LCD TV turns off by itself

Found that TV started switching off by itself. Would try to come light blinked for 2-3 seconds, tv came on (with picture and sound) for 1 or 2 seconds and then it would turn itself off. Found that the issue is with one channel only. If you are facing this issue....try quickly changing the channel the moment it comes on. You can do it either with remote or with the TV buttons directly. also in the same logic, if this is still happening, try changing the source to another (rgb-pc, av1, av2 etc). Basically change it from whatever input it is on currently, if changing the channels does not work. My symptom was that the tv made a loud 'TIK' 'TAK' sound which is louder than normal.
