This sounds like it might be a main board issue. Depending on the television brand there are different replacements you can get at different prices. I would try unplugging the tv from the wall first then try plugging it back in while holding channel up/volume up on the tv as you are plugging it back into the wall. If this doesn't change anything it is most likely a problem with your main board.

It will be best to buy a new TV rather than repair this set by doing a panel replacement. It might cost more than the price of a new one including price of panel plus service charges.

I see so many here with no sound/nopicture issues:


1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.4_23_2012_4_19_57_pm.jpg

Have you tried all inputs like with a DVD etc?

Vizio VO47L 47... | Answered on Apr 23, 2012

Look to see if same when you play a DVD or Blue Ray. If not it is not the set but likely a issue with the box if one is used.
