Hi,
I'm new to the forum and not an electronics tech or engineer. My Vizio 55" LCD TV recently developed an intermittent problem. Occasionally when I shut it off the Vizio logo below the panel will go from lit white to black. It normally goes from lit white to lit amber (or yellow or orange - I'm color blind). When it goes to black the TV will not power back on either with the remote or the jog wheel. If I unplug the set and leave it unplugged for awhile (the shortest period I've tried is one hour) and then plug it back in it will go into what I assume to be a re-boot as the Vizio logo flashes from amber to white and back for 30 to 90 seconds then settles on amber. The set will then power up normally with all picture, sound and apps working properly. This problem is only happening every few days.
I called Vizio tech support twice. The first time I was told to unplug the set and hold the jog wheel in for at least 30 seconds then plug it back in. This didn't work. When I called the second time I was referred to their tech support company, HD Repair. I explained the problem to the person who answered the phone and she told me she would talk to a technician then call me back with the problem. I called again the next day and she told me the technician said both the main board and the t-con board were bad (she called the t-con board a t-connector board). I suspect she didn't relay what I told her exactly to the technician as I can't understand how a t-con board could effect a non-normal shutdown or power up. I don't know if the main board controls power up and down, but that seems reasonable. I would certainly appreciate any troubleshooting help you could give me including if the power supply board could be the culprit.
Thanks very much.
