Question about Vizio SV420M LCD TV

Open Question

All the HDMI ports on my Vizio 42"

The HDMI ports as well as the Remote sensor is not working. Thought @ first could be cable. That wasn't the problem. Connected cables to Component 1 source get signal from Diretv. What board needs to be replaced to make ports work and remote work. Now we have to turn the tv on and off using power switch on back and have to control volumn with controls on back of unit. Those controls sometimes will stop working and just start working @ a later time when pressing them.

RJW34 I have a 37" Viizio LCD that has a similar problem. I power it up and I get a lit screen but it's blank. No controls work except power on and off.

My Vizio VU37L HDMI ports not working. AV ports work. Heavy lightning storm last night, TV was off when I went to bed, on when I woke up.


If you send the board to us we may be able to fix it.

What you're looking for is having to replace the small SMD IC that the tracks from the HDMI ports lead to.

Sometimes that is all it takes, other times it needs more and just today I've had a case where we just couldn't do anything as the damage seem to have spread to the large processor.

(it wasn't on a Vizio board, it was on a Sanyo, but the concept is the same)

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.

While most HDMI sources work with good audio and video, we have a compatibility issue with audio from a few specific products (eg, DirecTV HD DVR satellite set-top box, DISH Networks satellite set-top-box, and TiVo Premiere XL cable set-top-box). If you are experiencing problems with no audio or muted audio with one of your HDMI sources, then please try changing the audio settings on your problematic HDMI source to PCM or LPCM. Then turn off the TV, remote power from the WirelessHD adapters, and power off the HDMI source. Now power everything back on. If you are still experiencing no audio then please write down the model number of your HDMI source with no audio and contact VIZIO customer support.

HDMI ports stopped working. Only get a blue screen. Can only watch TV through AV.


If you have a cable box, then you have to pick the right source. So on your TV remote you need to pick the source button and then scroll down to HDMI 2 as the source. HDMI 1 is the blueray device. HDMI 2 to watch TV

Vizio Model#:L37HDTV10A After unpluging the HDMI cable & reconnecting it back, I don't have no more HD picture. The Component cable & HD antena works but no HD brodcasting with HDMI connection....


Is the HDMI port 2 work? Try to turn it off and turn it back on. If it is still not working then the HDMI ports have gone bad. You will need to replace the main board.
