My TV tuner gets the video just fine, but there is no sound. How can I fix this so I get sound?

Is the VCR going through ch 3 or video inputs - if video inputs your TV tuner is likely bad if through ch 3 seeif te picture goes funny on ch 3 without using the VCR the tuner may be bad on higher band channels - smetimes you can remove the tuner and resolder the tuner itself. But if it always works with the VCR just use it that way and don't bother with the fix.

Check your sound properties. It is probably defaulted to a low setting. Try raising the setting to one that says DVD quality and see if that fixes your problem. Hope this helps.

Think your set tuner is bogus. The other tuner that you used should work, but if it is not a cable tuner configured to your system it will not work either via the rf outputs or the audio video outputs. If that cable box works with another set then you have a real head scratcher on your hands.

it sounds like the tuner went out,you would have to know how to solder and remove the old tuner to be able to do it yourself

reset your tuner. Call the cable co for instructions...accordianman

It sounds like a defective tuner or a IF module as well. It may also be a defective capacitor(s) or cold solder joints inside the tuner circuitry. I woud suggest to use a VCR or a TV convertor connected to an Audio/video input to change channels instead of fixing it.
Good Luck.

Your TV's tuner is the problem. 1st thing to try is just to sesolder its connections to the main circuit board. If that doesn't work replace the tuner. Also could put a meter on the power coming into the tuner and see if it is drooping in sync with your picture. Tuners are not that expensive to replace.

here is a link for the driver, http://drivers.softpedia.com/get/TV-Tuner-Co/Others/MSI-TV-Tuner-Master-8606-WDM-279165.shtml

You need to plug the male yellow wire into one of the female wires that says media control...... something along those lines..... youll figure it out

If I understand your problem correctly it sounds as though when you watch your TV through the tuner you get nothing (no sound or picture) but when you watch it through the Aux inputs (with DVD or VCR) everything is fine. If that is the problem you either have a bad tuner or a bad matrix IC. I've seen both problems in this model and the cost to fix either is about the same. If you know TV safety and can solder unplug unit, remove the back, remove the main circuit board, remove the tuner from the board. This web address http://www.moteva.com/shop/customer/home.php?cat=267 has an original tuner for $18.00 US plus shipping. Install the new tuner and give it a try. If all went well this should solve your problem. If not you will probably need a service manual to locate the matrix IC. http://www.servicemanul.net for $16.00 US as a download. Locate the matrix IC. It should be on a vertical board on the left side. You should be able to get it at this website http://www.tritronicsinc.com This should resolve all your problems. If you can't solder or do not understand electronics you should have a repair tech fix it. Cost should not exceed $100 to $150 US. A free solution would be to hook up a VCR to the Aux input and use the tuner on the VCR and forget about trying to get channels through the TV tuner. It's your choice. Good luck and remember safety.
