Question about Televison & Video
Have sound no video
May be a defect but, if you notice the sound changes with different channels or movies or HD or Standard, look for a volume limiter control button in the menu setup under audio control. Sometimes the menu has a control that you can turn on to limit different volume levels during the shows origination.

Vizio does not, on the whole, provide panels for repair.
You will need to purchase a new set (or, if you have an extended warranty or manufacturer's warranty, a new set will be provided to you at no cost).

First check that any muting control is not activated. This might be
a button on the remote or set itself. If you have a headphone jack, it
may have dirty contacts as plugging in a headphone usually mutes
If the set is mono or only one channel of a stereo set is out, then
check for bad connections to the loudspeaker. Test the loudspeaker by
disconnecting one of the wires (with the power off!) and measuring its
resistance with an ohmmeter (it should be less than 100 ohms - probably
less than 8 ohms). Or momentarily touch a 1.5 volt battery to the speaker
terminals - you should get a click or pop from the speaker.
Next, trace back from the speaker output terminals to the circuit board
and look for bad solder connections or a loose or dirty connector.
If these tests do not reveal anything, you probably need a scope (or
audio signal tracer) and schematic. Or at least the part number off of
the chip. Is the final amp a chip also or just a transistor? Have you
tested the transistor? If there is little or no buzz from the speaker,
that would indicate a problem fairly near the output. If the tuner/if were
bad, I would expect some noise/humm pickup from the low level audio stages.
Get the part number off of the chip. If it is in a socket, check the
contacts for corrosion or looseness.
Hope this helpout.....

Find the model number on the back of the VIZIO remote control.
Go to the link below and enter the model number in the SEARCH BY MODEL NUMBER space provided or look for it in the scroll down SELECT YOUR PRODUCT menu.
You should see a picture of your product and underneath it a small grey tab marked SUPPORT about halfway down the page.
From there you should be able to safely download a copy of the USER'S MANUAL which will contain the codes for your TV. Just click on the user manual link highlighted in red.
While you are there you can also download a copy of your TV's user manual if you don't still have it. The tv's model number will be on a sticker on the back of the set.
Good luck, hope this helps. Keep us up to date on your progress.
