Helen,If you have already replaced the capacitors and verified that they are in correctly double check the wire connectors to the power board. You disconnected them to do the replacement and may have accidentally reconnected them incorrectly or not at all.

Hi Helen, This kit worked perfect for me, my TV was taking anywhere from 3 minutes to 15 minutes to start.I checked the capacitors and had to change 4, this fixed my problem.Its not that hard to chame capacitors, all you need is a soldering iron ($20 from hardware store)I would do a bit more research for your problem, but if it is the capacitors I would receomend you try and fix it.I have got some quick videos on how I to change them if you want them..Good Luck Russell.

The capacitor kit fixes power issues. ie: won't turn on for 15 or 30 minutes. You are getting sound but no picture so could be a different issue.All I can suggest is to take a visual look at the power circuit board (back most after back cover is removed) is look for capacitor damage (swellingor deformation) which could indicate that the capacitor kit might help you.

Without seeing your set, it is difficult to provide you with an answer. However, as a former TV tech, I suggest that you check the polarity of the capacitors that you replaced (Make sure the - and + leads match the board diagram) to ensure that they are not installed backwards. Also check the quality of the solder joints. A cold solder joint will shut you down. Make sure that you have reconnected all cables and that the pins are not bent or broken. Sorry I can't suggest anything else. Good luck.

Is the volume on your TV turned up? Is the volume on your phone turned up? It's odd to get video but no sound.

If it is still on warranty my best suggestion is to call amazon and have them replace it, or you can call LG directly, or go into your local electronics repair shop. Good luck and all the best to you and your family for the new year. Regards.

Try putting in a USB memory stick and then updating firmware. You could plug another blu ray player in to this device using an optical digital cable. I plugged an Xbox in that way, until throwing the whole thing away and swearing off LG devices in this line. The player is junk and LG washed their hands of it and orphaned it.

I never tried this (and I am not currently home to try it), but I am going to assume the answer is no, based on the product manual I pulled up online (http://www.samsung.com/us/support/owners/product/UN46D7000LF). In the troubleshooting guide, under "The picture is good but there is no sound", one of the solutions is "If your TV has a headphone jack, make sure there is nothing plugged into it."

No Sound.....Hence the no HDMI. I've hooked up through DVI and it's an AWESOME picture

Make sure the speakers are connected correctly, and the colored part is connected to the same color on the back of the device. If that fails, I suggest RMA.

Make sure your input src is clean. If you pass through the tv it may not work, get audio straight from the sat box or whatever and make sure that outputs dolby 5.1.

Great Granny,I would try to exchange or return the tv while you still can. Only a minority of Vizio's have picture problems and you are certain your tv has a sound issue. If you were to use external speakers you might still have a sound problem anyway. Good luck.

Unplug the power and plug it back in. If you don't see a picture, it might be stuck in the wrong video mode. If it is, you might not be able to fix it without plugging it into a television that supports the mode it is currently in.

Onkyo now has a program where they will fix this issue of no sound. Mine just died after only 1-1/2 years. Here's the web link: https://repair.onkyousa.com/na/003_2012.php?country=USA#serialModal

My TV was completely without picture so I sent it back and bought a Vizio. Sorry I can't help you further.

There is not a audio output on the LN5100 - the only way you can run a soundbar is if you hook it up directly to the source.
