If you have Chrome cast with Google assistant paired to your Tv... ask Google Assistant to "change the channel to ESPN (or YouTube) on the living room tv. (I had not figured out how to add apps I actually want... Google Assistant or Alexa works for me.) No app is needed.

Yes it is repairable and you will know in future not to buy Visio. They are bargain basement at Sharp / Sony prices! https://www.fixya.com/support/r29790007-repairing_own_television Take it apart and power the LEDs independently using a variable power supply. They should all be the same brightness. Or..... take it to a pro and get the job done right. ..

Try updating the software, if it doesn't have net connection you will need to download the software from Vizio on a flash drive and instill it, this should fix it

The Vizio VO230E does not have network capabilities built in. The TV has built around 2009 before many TVs included either wired or wireless networking. The manual has the specifications on page 61; the manual is available here: http://cdn.vizio.com/manuals/kb/legacy/vo320emanual.pdf . To get a wireless connection, you need to connect some sort of streaming device with wireless networking to the TV. This can be a computer, a ChromeCast and your phone or tablet, a Roku device or another streaming box. Plug the HDMI cable (or device plug) or the device into one of the two HDMI ports on the TV. Connect the device to a power source, if one is needed. (For devices that use a USB power connection, do not connect the USB power cord to the service port of the TV. Connect it to a charger.) Since your choice of devices range in price from the ~$15 Roku Express to several hundred dollars for computers, depending on the specifications, you will need to decide which features/platforms you want. I hope this helps. Cindy Wells

I've seen this a couple times on a Vizio TV, not sure the model however. If I remember correctly I ended up replacing the main board to fix the issue, if you test the 3.5 volt regulators on the main I believe you will find the same input and output voltage on one of them.

All the issues you will encounter trying to repair yourself if a power reset doesn't work. https://www.fixya.com/support/r29790007-repairing_own_television ..

Hi Ben, the 2 boards aren't interchangeable

Press the mute button to unmute it.

There is no way to know for sure without taking it apart, but chances are its bad lamp strips, I'd say 9 out of 10 chance of lamps

Hi Ross...the "E" series Vizio TV's have a very slow processor and have been known for the issue your having, do a factory reset, you will need to reload everything after you do the reset but it should fix it, or for awhile anyway. Only other thing, after the reset turn off auto updates, that's part of the issue as well, they keep adding more junk that slows things down...Good luck!!

Not all universal remotes work with all TVs, if you have followed the instructions that came with the remote it doesn't work with your TV, instead of trying to program a remote order a factory remote on ebay for around $5.00

Ho Joe...I suspect your LED backlights are bad, this model doesn't have local dimming so complete lamp failure is possible. A couple things to test, you need to make sure you're getting the signal to enable the inverter, look for around 3 vdc at the bl-on pin on power board, if you see that chances are really good it's bad lamps and over voltage-current is shutting down the regulator side of the inverter, the reason you see voltage on the 2 B+ lines to frame ground is they regulate the minus side of the supply. If you have a 330 ohm 2 watt resistor you can jump each minus side and you should see the working lamps light but it really doesn't prove anything other than some of the lamps still work

This article I wrote explains the problems you are facing and is based on 15 years on this website. https://www.fixya.com/support/r29790007-repairing_own_television ..

bad color board or screen

Hi Reb...I think I know what your issue is but need a model number to be sure.

You are reaching out to Fixya, we are not Vizio. Blown capacitors could certainly be the reason if it has also failed internally. Just solder in a new capacitor. A quick search shows it is a known issue on that set and in Just Answer dot com, the tech says it needs a new main board. https://www.justanswer.com/tv-repair/8fdkz-when-plug-vizio-e322ar-black-screen-rolling.html Vizio says do a Power Cycle. https://www.google.com/search?q=vizio+e322ar+black+screen ..

Panel issue

You can buy an OEM remote for less than $7.00 on amazon. If this does not correct problem, you will have to suspect TV remote receiver

Unfortunately, this sounds like a panel issue
