Two vizio TV's with issues


Take them to a TV repair centre as they are complex to repair. You may find that your homeowner insurance will pay for the repairs if you can demonstrate that it was a power surge that damage them.

Sv421xvt turns on for 10 sec then off


Most likely a power supply issue. Many of these LCD panels have particular problems. If you search on that make/model you will likely see similar complaints. If you have no way of testing it, you could take a chance on a replacement board - but this will be around $60 to $80, so balance that against the age of the product and the replacement value.

42" Vizio 240Hz SV421XVT no hdmi video or audio


Possible bad source, bad cable or connection was made with units powered up which HDMI does not like.

First thing to try in this case is to remove power from set and whatever unit is connected via HDMI and disconnect the cable itself.

Wait for several minutes, connect HDMI again and THEN return power to the units that were removed from power, this cannot hurt and may help or correct this issue.

Failing this try if possible to connect using component connections.

Problem with Vizio SV421XVT


I am also having the same symptoms for my SV421XVT. TV works great except all HDMI ports are not receiving signal. Devices work through the AV Ports, and TV reception is fine. New Roku box is also not working through HDMI but works with AV. Wish I had a solution to this.


On a another forum for another TV it was suggested that boards need to be replaced. I hope I can get these boards for a reasonable cost.
