Have TV Questions? Ask a TV Technician
Thank you for your question.
If you have cable box or satellite receiver try unplugging it for a minute and plug back up.
Or try unplugging the tv and plugging back up also.
Thank you...The sound circuit may have been damaged and it is located in the MAIN BOARD.
Does this set have a built in DVD player or is the DVD player you mentioned separate?
OK thanks...It occurred to me to check the menu to see if the speakers are turned OFF
To locate a MAIN BOARD availability you will need the model number and do a search on CLICK HERE and match the board numbers with the one in your set.
Once you are sure you have located the correct board you can either purchase from that link or shop with part number on Ebay. It will require simple practical experience taking the back off the set and unplugging and unscrewing and putting new one back.
Did you unplug the tv?
You could also try changing the HDMI or RCA jacks to a different location on the set
The HDMI cable or red white yellow cable. to a different plug on the set
Most tv's have at least 2 locations for these cables
When you change the cable the setting will have to coincide in the input menu
This is a long shot but however a possibility.
Located where all the plugs are for signal could say AV1 or AV2
yellow is video and red is right audio and white is left audio
You have to see how you already have your signal hooked up
either HDMI OR RCA CABLES
I recommend changing to IN 2 the three and making the change in the menu
That means the MAIN BOARD is likely received damage due to improper input.
Of external source
Provided you don't have an audio amp hooked to the tv
Then I recommend changing the MAIN BOARD as previously mentioned as it contains the audio circuitry
It's up to you but if you have future questions..it may pose a problem
Please rate positive
To be honest, if you don't rate at all I think you won't be charged but future service will be hindered
Ok have a nice day
