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

Wow, I feel stupid! Solution #2 did it! There are 2 Tv buttons, one on the top right and one on bottom right. You have to press the bottom one!! THANK YOU PPL!!!

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!

Please try to turn off the closed caption function by access the TV set up manual

Please check the electrolytic capacitors on both of the back lights inverter board, if any of them has over heated bulging & leaking, replace them. we will replace them all.

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.

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. 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.

If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ Line faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size.
