Re: Sharp Aquos 4.5 yrs old had an audible pop and no...
There are a number of things that could be wrong. The basic first thing to try is to replace the cable(s) that feeds your TV signal; sometimes the connection with the connectors on the end goes bad. HDMI or what ever feeds your signal. You can make your own RCA or traditional F type coax connector with the connectors from this site or you can buy what you need for composite or RCA at your local store. This could be the problem if the signal has just stopped coming over. hopefully that is the problem.
Next is the bulb in the bulb should be checked. In an LCD it can just happen. the light dies. if you are getting no sound and no image the bulb is likely not the problem.
You may have a short or bad resistor or transistor. the board that controls your TV might not be getting proper power, be it too much or too little. If you suspect this is the case leave the TV off, that pop could be a power surge flowing over the components of the TV. and could do further damage.
Depending on the value of the TV you should consider recycling. Replacing a TV under 300 or 250 is worth it. a warranty is included. an involved repair could run 300-400 dollars or more, but on a big screen TV that costs over 2,000 a repair is a good value.

I'm assuming you have a high definition cable box connected to this television with an hdmi cable a motorola perhaps. If that is correct then with you motorola cable box power turned off press the menu button on it. Yes I just stated that you turn off your motorola cable box and then press the menu button on it. A hidden menu will pop up on your television screen. Yes the television should be turned on but the motorola box should be turned off when you press the menu button. I am sorry for reiterating that so many times but there have been numerous persons that have been more concerned about why this works in this way than just getting it to solve their problem. So you navigate down to the color space setting. You will be able to navigate left or right to choose a different setting under color space. You will see maybe RGB of YCbCr 4:4:4. Choose the one that your cable box is NOT set to currently and the green line should go away.
This is definitely not a Sharp Aquos feature. Any show related functions come from Dish Network. It might be a channel specific function which the Dish Network support staff does not know how to deal with.
Not sure if I just got lucky or if the problem is solved..I hooked up my Sharp Aquos LC-32D64U the other night and I had the blue audio box pop up. Mine was only in Mono and would not switch to Stereo...Well, Local cable company is of of Hi-Def boxes but I thought what if my Digital box is bad/old or has some sort of problem. I went down to comcast cable company switched to a different digitial box..came home, hooked it up and so far no blue audio box, plus now it shows that it's in stereo..good luck
TV is under warranty. Get a tech to look at it. It could require a new IR sensor, a firmware upgrade or a system reset that only a tech can do called an Industry Initialization that is in the service mode only
When I first bought my Sharp Aquos 42 inch TV...I started having sound problems...turned the volume way up to 60 maximum and could hardly hear it.
Then after the TV was on for 4 or 5 hours, there would be crackling chirping popping noise. It seems after the TV heats up for awhile...there is MAJOR sound problems.
So I was advised to buy a Sony surround system and connect it to my TV...deactivate the TV volume and use ONLY the surround sound. I did that...but the surround audio cables are connected to the back of the TV and I get the exact SAME problem with chirping and crackling sounds after the TV heats up.
SHARP IS NOT BEING HONEST WITH CUSTOMERS.
There should definitely be a RECALL on the sound board.
Replacing it does nothing....the overheating of the TV just damages the new sound board and the TV has to be repaired again and again.
I have the same problem with my My LC-42D62U
WHen i watch certain DVDs, (so far it happened on SAW III and RUNNING SCARED)
during certain parts of those movies my TV will turn off and i cant turn it back on unless i unplug it and plug it back in. It only turns off on specific parts in the movie, i have no idea why...like the same exact parts...so i pretty much have to pause the movie with my remote once my TV turns off then when i power the TV on again just resume the movie and its fine...but if i rewind to that part again it'll power off again
SAW III only had one part like that....but RUNNING SCARED had about 3-4
