20 Most Recent Vizio VO47L 47 in. LCD TV Questions & Answers

For the cheap guy like me who will probably do more harm than good:
Also check for the F3 Fuse on that same main input board. It is located in the upper right corner. Hard wired fuses; very small. You will see F1-F4 (F4 is empty). You can solder a replacement fuse right over it. I would recommend piggybacking the fuse with a fuse you can replace. Will need the holder and a new fuse. 6 bucks.
Doesn't solve problem, but I can go another 2 1/2 years and the wife won't blame me for screwing up the TV in the first place.

Yes, changing the main board should correct the problem.

Power doesn't have to be knocked out for a cable box to destroy the HDMI ports on a TV. Thunder miles away will put voltage spikes on the cable system which in turn trashes the main board in the TV. You can get parts for your TV here: TV Parts Universal TV Stands DLP Chips ShopJimmy

After only three days I would take it back, or at least take the remote back and try it on a different sound bar.

Visio might not have a headphone jacks at all! Look around your set and, probably you won't find jack marked as headphone. You might need to use wireless headphones, what have an rca plugs and connect them to audio monitor out on your tv set.
Good luck!

I think unless it has a power converter...the straight plug should work...think about it...they didnt have to pay to get rid of it.

Defective LED back lights strips, or damaged EEPROM on main board. I will try a main board first, if you do nor have a TV LED strip tester.

Sadly, only testing of each component can suggest the extent of damage. Many years ago, lighting can in through the window of my living room, hit the TV, blew the knobs off the TV (that date's me), shot into the kitchen and shattered the kitchen counter top. What I want you to take from that is that the course of a power surge is a bit unpredictable. No one can guess how far it got until you find a lamp that works.

Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Despite of no image do you still have sound(happens in case of malfunctioning backlight or T-con board)?

My 47" LCD Smart T.V. was working fine last night. I got up this morning and I have sound but no picture. The VIZIO icon lights up as usual but I get no picture, only sound. From the time I turned it on, nothing appeared on the screen. I have already tried unplugging it for a while and still nothing.
