I do not understand it well. Sound coil? What sound coil? There is a voice coil. But it is inside the speaker. If it has damaged, will be very difficult to replace. Speaker should be replaced. If this coil has damaged, you won't get sound from your TV. That is all. Picture will be there. Ask your technician to give you the number of part [sound coil], that he has detected faulty. Send that number to me. OK?

You are right that this is a common problem for plasmas regardless of the brand. They all have similar boards on the inside that do the same thing and usually it is after a couple years of use. If your set has quiet cooling fans on the back, they after time attract alot of lint and dust and moisture from the ambient air that causes alot of y-sus and z-sus boards to fail. I would at least take the back cover off and blow out all that dust that has accumulated. If it is out of warranty as I am sure it probably is after 2 years, you certainly will not hurt anything. Call tech support at AKAI, I am sure you will not be the first to log in this complaint. Those tvs are suppose to last through 60,000 hours of use (20 years). Be firm with them and they may just give you a replacement. Some people have been successful at pleading their case after the 2 years are up on the warranty.. I hope this helped. God bless and good luck.
I just had that problem. Check the terminal board that is on the left if you open the back of the TV. There is a thing in there with the number aa93-something. If you check under that board there should be some solders that have come loose. I just fixed this problem last night!!
This is a typical power supply problem. Please check the B+ Power Supply that goes to the LOT (FBT). It should be 110V. If that is ok, check the voltage while increasing and decreasing brightness, sound. If there is variation, the problem is in the SMPS. Look for dry capacitors, open/high value resistors, zener diodes, transistors etc. If nothing works, please download a data-sheet of the IC and check voltages at the pins and locate the adjacent components. Even a dry capacitor in the power supply can decrease the votage at load
