A woman called that her Vizio VA370M did not have picture from a coax. I noticed the metal coax input is bent up. The HDMI inputs work when I hooked up a blu-ray.
Can this coax input be repaired?

Re: Vizio VA370M Coax Input
look for a crack in the solder joint where the coax connector ties to the tuner board, pretty common failure pointLiberating magic smoke one part at a time -
Re: Vizio VA370M Coax Input
Sometimes you have to unsolder the tuner of the board, which would repair the coaxial jackComment

So, I have a really bizarre issue that I'm struggling to identify the cause of. Working on an 820-02020 board with some bizarre keyboard/input-source character mapping. My suspicion is a possible damaged SPI ROM (U1970), perhaps, but I'm really not sure in this case:
1. The issue is pretty weird, but when installing MacOS, I noticed my WiFi password did not work. I quickly realized the special characters (!@#$%^& etc) were not mapping correctly.
2. I noticed the keyboard layout/input-source is defaulting to JAPANESE every single time I restore the board. I am not... -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Failure Symptom
No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.
Where is the short?
Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.
Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but... -
Hello,
I have a 42" Vizio TV. I hooked my tablet to the HDMI inputs. Everything was fine until the screen went black and now the only input that works on the TV is coax. No hdmi, no component, no rca. I tried hooking up a laptop to the Hdmi port and the computer
detected the TV model but no image.
Is there anyone having the same issue? Did you find any solution?
