You have a bad audio output ic. The ic in this set is very difficult to change, so most techs will change the entire digital board. If you can find a digital board for it, that would be the easiest solution, and can be done easily yourself. You can try ebay or shopjimmy.com to try and locate one.

It can either be the T-CON board or the main board, or LCD panel itself problem, you will need the scope to look at the signals feeding the T-CON board and the output of the T-CON board to narrow downth problem.

Let verify first to narrow down to where the problem can be. First, check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.

The LCD controller (T-Con board) or main board needs to be replace to fix the no video failure.

Check backlight (cold cathode) if busted. Check also for deffective ballast as this have direct effect on the stability of image in the screen. Replace it. These two are the main cause for having black screen.

You need to check your antenna and see if you are actually getting a signal, also hook something up to the External inputs and see if it actually can display a picture? So, it is nearly always my professional opinion that one should always get a "Quote" from the manufacturers recommended service center, I cannot stress how important that last point is. It is even worth the cost of shipping. you see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option. As an aside here, one could then tear the TV down, and sell the Known Good bits. You'd be surprised who needs parts, i myself often must by from third party sources to effect a repair. So money could be recouped, somewhat,and help out someone else.

YOU CAN'T!
This is from another website, I thought you might like a second oppion too!
"For your information no one can repair cracked LCD Screen. In order to solve the LCD panel cracked problem, the best is to replace with a known good LCD panel."
