Question about Flat Panel Televisions
In your post, you said that you fixed the lack of sound issue by running through all of the channels. Can you explain this a little better? I can't figure out what you mean and I spent an hour going through the different options on the menu of the TV. I really would appreciate any help you can give.
SOURCE: no sound on analog channels
Grab your sharp remote and press MENU, arrow over to SETUP, arrow down to RESET and press enter and follow that prompt to reset the unit. Once that is complete turn the tv off and unplug ONLY the tv for one minute then plug it back in. Then turn the tv on and see if you have channels, if you do, your audio should work on you analog stations, if you have no channels and all you see is a snowy picture do the following press MENU, arrow over to SETUP...arrow down to CH SETUP and press ENTER...you will then be at a screen that says AIR/CABLE, press ENTER, select CABLE or CABLE(STD) if that option is available to you. after then, arrow down to CH SEARCH, press ENTER, then you should be highlighted on ANALOG AND DIGITAL SEARCH...press ENTER and wait for 15-30 minutes ( or until you get a picture back) and make sure you DO NOT press any buttons or turn the tv off and you should be good. good luck 2 u

I had almost the exact same model. Mine was a 9631D, built on the same architecture I believe. I can say, if you heard a POP noise, before the picture went out...You are most likely looking at your Y-SUSTAIN, and Z-SUSTAIN boards. Don't let this get you down. Look closely for any blown caps. And You can not only replace one board. unless it's the Z. If you only get the Y, without the Z, or vice versa, you can damage the new board, and end up in the beginning scenario.
Hope I helped,

You need to test the unit on a external sound source, to see if the audio amplifier is working correctly. By checking it on another source you can determine if the sound amplifier system is failing or you have had some problem with you speakers. Once you determine the problem. If it is the speakers, you can replace them with new ones. However if it is the audio amplifier section failing you will have to take it to a service center where they have all the service information to do the repairs.If the unit is still under warranty, have it serviced by Insignia. You can reach their customer support with this telephone number !-877-467-4289. Give them the model number of your television and the problems you are having with it. The should be able to tell you how to have it serviced. You can also check out their website for customer support at www.insignia-products.com. If the unit is out of warranty, you must have someone help, you troubleshoot the problem and try buying parts for the repair. You can call this number for insignia parts. 1-888-237-8289. You can also search the Best Buy website for parts on these units. The website is www.bestbuy.com. Go to the parts search section and put in the brand name of you television and put in the model number. The search engine will bring up a parts list with prices. I hope this information has helped you with your problem. You should also be aware that Best Buy has had a recall of some these model units. Check my tips and hints postings for more information.

This should be a piece of cake for you.
The best thing you need is a Service Manual for the TV. Costs about less than $20 over the internet. It will have schematics, diagrams and part number list for the TV. It's the best thing to use for diagnosing the problem on the audio board. It maybe something simple like a conductive adhesive material for a heat-sink that spread to other contacts on the board.
