Re: Vizio M420NV display is mirror image
The problem was the Main Board. The indications were as follows: mirror image on video and menu display, no sound from speakers, one non-functional HDMI input.
I just wanted to let everyone know that this TV has been repaired.

Re: Vizio M420NV display is mirror image
Well, this is bad news... This is from Randy at shopjimmy:
"A fold-over issue such as that means a short in the lcd panel most of the time, The t-con usually will not cause that issue. Mains almost never can cause that issue.

Re: Vizio M420NV display is mirror image
Well, I was able to get to "Help" and "Reset to Factory Settings" by entering 0000. The TV reboots, but comes back with the same reversed image. In all my searching, it looks like the TCON board would be the culprit, since both the screen display AND the menu are both affected. Going to call the guys at shopjimmy tomorrow as they have some of these boards for sale. I will get their opinion before ordering one, though. $51.95 is cheaper than a new TV if this is really my issue.Leave a comment:

Re: Vizio M420NV display is mirror image
Powered on-off, also tried holding the power button for 30 seconds, used the remote to do a reset to factory settings. Nothing simple seems to work. The question is, where is the problem? Main Board, T-Con Board? How do I tell where the image is being reversed?Leave a comment:

Re: Vizio M420NV display is mirror image
As far as we know, it has not been worked on by anyone previously. The TV was working fine last week, but over the weekend we had some bad weather and power was lost to the building. So, I suspect a power surge of some kind has caused this mirror imaging issue. Of course they did not have the unit plugged into a UPS.Leave a comment:

Unfortunately, this TV belongs in some manager's office, so just leaving it reversed, or using a mirror is not an option in this particular case....Leave a comment:

Vizio M420NV display is mirror image
To the brain trust:
I have a Vizio 42" TV on my bench that powers up and lights up just fine, but the image displayed on screen including the menu is a mirror image of what it should be. From what I gather on other posts, this would be a problem located on the main board and would not be fixable with any kind of a reset.
Is this correct? Should I start looking for a replacement main board or is there any component that I may be able to replace and get this thing working properly?
Thanks. -
