I agree your screen is cracked. It's smooth to the touch because you're not actually touching the LCD section of the screen, just the protective coating. The advantage of owning an LCD TV over plasma... you can replace the screen either by going to the manufacturer or some place like e-bay. It's not a difficult thing to do if you take your time and pay attention to the details.

Spent 3 hours removing all what seemed like 100 freaken screws.
Took out the OEM 6871QCH038A (038A), it is the last board after you pull the cover, bar, top input board, sits right behind the aluminum shield of the plasma screen. Caution the factory placed some type of heat transfer silicon clear grease on the back of the board so it will feel like it is glued on. Just be very carefull and gentle when prying it apart.
Be warned, you will need a magnifying glass to check those little resistors. They all checked out, no broken solders.
What I did observe is the grease melted down the back of the board and puddled at the bottom of the board and where the resistors sit.
I used rubbing alcohol to clean it all up but left the reside on the square pads. Cleaned the resistors and used a dry paint brush to dust of any lint.
Placed the component back and after 10 minutes the Vertical Red Line Disappeared.
Turned on the set next morning it was still gone. 10 minutes later it re-appeared for a couple of minutes then went away.
I spoke to a kind gentlemen at Electronica-USA.com, he stated that the 6781QCH060Q (060Q) is an upgrade to the defective proned 038A ( 038C is also an upgrade ). A tech in Cali stated the 060Q worked perfectly. He has had zero complaints about the 060Q in the Vizio plus he offers a 90 day return policy. Funny thing is the 060Q was designed for LG and Goldstar Plasmas but for some reason they do not work for them but do work for Vizio's. He even states that on his site.
As I type the red line is still gone and stayed off several hours last night.
I think I am going to pull the trigger and replace the 038A to the 060Q and be done with it.
Oh yeah, I asked him if the 060Q needs to be "flashed" with the Vizio program. He never heard of it requiring it.
He has 038C on order they are couple of bucks cheaper. the 060Q is $224 plus S&H.
I found on ebay for $184 free shipping but waiting for the guy to verify no "flash" requirement.
Hope this helps someone.
Merry Christmas and a Happy New Year!
P.S. use a power screwdriver, your wrist will thank you. I put mine on low torque as not to strip the heads.

Looks your power supply quit. Get a new one from vizioparts.com might cost a buck and a half,plus an hour of labor, but 52"? deffinetly worth it! Vizio is good on parts. Make sure, have your serial# ready. some sets have been modified within a year, might get a wrong part without ser#.

This is the best solution for your problem as a 40 year experience with wires etc. Go to the source of your cable signal connector . Open it and clean the terminals with emery paper , sand the end of the cable shiny clean from corrosion , get a new barrel connectors with gold terminals if possible lengthen the ends of the cable , insert and tighten good, use thick rg-16 or rg 40 cable with good insulation ends crimped professionally with a crimpier or buy ready made , not from dollar store. Get a gold plated professional splitter if you need one or two , it will cost about 15 or more each . Make the cable runs as short as possible, using the thick good cables. If needed get a signal magnifier. From radio shack or the source etc. Connect them good and tight . Ground the splitters . Problem solved , you will get crystal clear channel 2 to 7 including 3 and 4 . Isolate the TV cable from other cables and power wires. Vitally
