Hello, I'm Shahid. Sorry to hear that you're having trouble with this and I'll do my best to help but need more info to troubleshoot the problem.
- Could you please get me the complete model number written on back cover or side panel of TV?
- What video devices/ sources (such as cable box DVD player etc) are connected to the TV and does the problem occur on all video input sources?

OK, it seems sound processor chip on the mainboard of TV has got an internal fault and causing no sound and you would need to replace mainboard of the TV to fix the issue. Sorry for this news.

Please click the following link to view mainboard image and part number info to search/ google it to get price info if you have a plan to work on ti yourself...

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make the decision about this TV repair or invest that money in new replacement TV.
If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page so I can get the credit for my work on the website.

I wish there were other things to try, the mainboard isn't supposed to be repaired on component level nor the spare components and detailed schematics is available to do that repair so the only option is to swap the defective circuit board/ mainboard for any trouble related to it.

Thanks

I've fixed another TV by replacing the capacitors on the board. Is there a way to just fix whatever is broken on the board rather than paying for the whole board?
