Question about Vizio Televison & Video
Unplugging the tv changing batteries in the remote
Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

I had a similar problem after having a Vizio for 2 and a half years. I
left the room for a minute, i came back and the screen went black. I didnt hear an arcing sound though.
There was still power to the unit and you could see that the back light
was working, just no picture, no sound, and you couldn't use any of the
buttons. The only way to turn it off was to unplug it. It would then
start up, with the Vizio logo going from orange to white, and then do
the same thing all over, no pic or sound. I would check the ceramic fuse first on the board that gets power from the plug.
HOW I FIXED MINE: I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine.I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

Testimonial: "thank you for your quick response- the information really helped me solve the problem"
This sounds like you are experiencing the same thing as thousands of other tv owners right now.
Your tv is suffering from " capacitor flu".
The capacitors that control voltage regulation, convergence, or the ones on the main board have failed.
This is not due to anything that you have done, it is because about 15 years ago, some companies chose to put profit ahead of quality.
There were about 20 electronic component manufacturers in the mid-1990's that mass manufactured capacitors, and they were done so with the wrong formula for capacitance gel. They used a formula which was later determined to be harmful to the capacitors, but instead of pulling those off of the market, they ignored the massive failures and left then out there on the market anyways.
All together, the companies made a combined 50,000,000 capacitors that were junk, and instead of lasting the 25-30 year design like they were supposed to, some of them are only lasting a few months to a few years, at best.
Now, that isn't to say that this means that your tv should be tossed in the trash, but if you take it to get it repaired at places like BestBuy, Fry's, or Staple's...you will want to get an estimate of repair costs before actually having it done.
The reason for this is because to get the proper capacitors put in your tv is a time consuming, and expensive repair.
You may find that the cost of repair is more expensive than the cost of replacing the tv, or you may find that it reasonably priced to get the repair.
That is why I recommend getting an estimate first.
This way, you will know ahead of time which way is the most economically feasible venture for you.
I hope this helps you understand what is going on with your tv, and that it gives you some insight as to how to remedy the situation.
Good luck to you, and have a good day.

If new batteries did not fix the problem, then it means the problem is either from the remote or the TV.
You need to do some diagnosis to confirm the source of the problem.
Remote: Check the remote battery terminal, see if its not rust. Also, disassemble the remote, can check the connection between the terminal and the remote board, see if there is no disconnection of any kind.
If after checking and all seems well, then it means the remote is defective. To confirm, borrow a remote, test it with the TV. If it works, then it means you need to replace your remote. But if the remote you borrowed does not work, then it means the problem is from the TV and not the remote.
TV: There is a sensor in the TV that communicates with the remote. If this sensor is defective, the remote won't communicate with the TV.
The TV sensor might have loosed contact from inside of the TV or it maybe defective and need to be replaced.
So do the above troubleshooting and let me know if the problem is from the TV or remote. If problem is from the remote, you need to do a replacement. But if otherwise, let me knows as well.
