On the sharp remote you will find an input button. You depress the input button and a menu will appear and highlight the input you are presently on. Hit the input button again to select the next input. If you wait to long to depress the input button it will not work and you have to begin again. This unit will only hightlight inputs have a component hooked to that input.

Good day, Bgchzy;
This model is known for the tubes leaking fluid, glucose, on the PCB. Check the front of the chassis for said fluid, it may be only a drop, so look closely.
To fix, after TV has no power, try cleaning the board with cleaner and brush, let dry. I suspect this because of multi unrelated problems.

Old messages and bcipollina is gonna get to read this resonse twice; sorry-
If it just fails to turn on or ignores the remote, the
main power supply is probably at
fault and without some technical background and a couple of test instruments,
you will not be able to do the repair yourself.
What you can do though is; unplug the set, let it
stand overnight or at least several hours, remove the back panel and look for a
separate board with mostly larger components on it; it will have a ferrite core
transformer on it and several larger capacitors which are cylindrical and
mounted vertically to the board.
Before touching anything inside,
especially on that board, allow several hours to be safe since the larger
capacitors can hold a painful voltage charge for some hours.
If you see signs of overheating
such as discoloration of the board material, it may not be repairable but if
you can find a part number on the board, you might be able to buy the power
supply and install it yourself.
If there are no signs of heat
damage to the board, there may be companies offering to repair it as a
subassembly instead of repairing the whole set which could be much more
expensive.
If you choose to replace or have it done, the power supply still may not be at fault since most
are capable of switching on and off if a downstream problem is causing an
overload.
BTW, from what I have read about Vizio, I think they are close relatives to iLo which was also sold by Wal-Mart.
Quality control anyone?

go to menu setup and do the full system reset setup option... Then before you scan for channels make sure it is set to cable... This fixed the problem for me.

I just talked to a tech and fixed mine. unplug tv and hold power button for 1 minute. this drains the compasitors, sometimes they get over charged. if that doesn't work. with tv off hold down input button until tv turns on . it should work. here is tech support # 714-668-0588
Press "Input Select" on the remote control and select "TV Mode."
Press "Menu."
Press "Enter" to select "Picture."Use the arrow buttons to select

Depending on the model TV you have, there are up to four ways to change the video source:
