Question about Vizio VO320E LCD TV
The TV is currently connected with coaxial cable to a Direct TV box. We wondered if we could open the back and test the cables in any way. Before we replaced the mainboard, the Vizio logo light came on but would not turn off and screen remained black. At the time of the lightening storm it was off but was connected to Direct TV box with HDMI cables. It was on a surge protector which no longer works and the HDMI output on the old box no longer worked.
Mr. John either one of two things from start u have done right this is a common thing on flat sets hooked to Direct boxes by HDMI having surges come from box to set. The main board usually needs replacing, so either u received a bad board or u have multiple issues and possibly the T-CON board got surged from main board. This board is located above main and power in center at very top of screen. This will cause symptom that u are describing. Hope this helps.

Don't replace anything, Vizio has issued a lifetime warranty for this set because of this problem. No joke, call the customer service line and tell them you got the pop of death. They'll send someone out to 'repair' the set free of charge. If they can't fix it they'll give you a new one. Even if your mfg purchase warranty has expired. Call them and post the results. I've been fixing TV's longer than I care to admit and this is the first time I've actually seen a company stand behind their products like this. I bought a broken tv with the intent of fixing it and after replacing almost every board I could only manage to get the vertical racing stripe line, except mine was purple. I put it all back together and called to find out if there was a recall on this set and within 5 minutes the (Actual English speaking) gentleman told me to sit tight and he'd have a repairman come and do his thing. He did, and long story short, he couldn't fix it. Last week they delivered a new TV to replace this one. I was shocked. I think Vizio will have all my future business.

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.

I recently had the same problem with my vizeo hdmi port # 1 going bad. Tried everything to fix and called vizeo. There solution for a master reset was turn off tv and unplug from the wall. then hold down the power button for 30 secs and let go. plug the tv back in and hold down the volume down and input select buttons down on side of the tv for 15 secs. release the buttons and turn the tv on after powering down all the components connectd to the tv. If this does not work they told me you need to have it sericed for a bad hdmi input. Hope this info helps anyone out there. It didn't work for me. Its a bummer cause the tv is well taken care of and only 18 months old. Best of luck to all others.

sounds like you needed to replace your video fuse before anything normally if you have video but no sound its an audio fuse and vica versa if for some reason both were out I would say your in need of a new power supply I would suggest replacing the fuse and if it still does not work contacting a service tech to run a diagnostic to see what exact part or maintenance you need

Logic Control D Board got nothing to do with this problem. This is your main power supply gone bad(usually not the sub power supply). I just repaired my VIZIO by replacing main power supply. Just remove back cover and your board will be right in the middle of the screen. Just get board part/serial # and google it. My best price was through eBay(around $100). Everything is fine now.
