Question about Televison & Video

Open Question

Poor audio level range - My Sharp AQUOS, LED 46" (Mod # LC-46LE700UN) TV sound output level control shows a range of zero to 60. There is a "normal" (linear) output level, i.e., a gradual increase in sound level, to 30 (mid-scale). At that point in the range the output level is nearly "flat" - - a bearly preceptiple increase in sound level between 31 to 60. While our hearing is NOT impaired, some programming has given us the need to increase the sound level to compensate for whispered on-screen conversation - - and we cannot!!!!! Is this a repairable problem?

Background:
This "K" message is actually a factory service mode used for bench testing. You might have accidentally gotten into it somehow.

How to fix it:
The only way to get out of it is a series of button presses, known only to Sharp (1800 237 4277) and service centers. Though the latter will charge you to clear the message. Call Sharp and ask to speak with their 'dispatch group' to get around this.

SOURCE: TV No Picture

My 32D40U would turn on for 5-10 seconds (Please Wait would appear) and the screen would go black. Sound Normal. It would also sometimes do this after running 5-10 minutes. I read somewhere that the inverter board would come loose and lose proper ground. I took the set apart, removed the board, and cleaned up the grounding points. I reassembled using some copper paste on the ground points and LockTite on the screws. I used some contact cleaner on all the connectors going to the board. I noticed two cables that are covered with copper shield tape where too tight at their connectors and repositioned the tape to give them some slack. The problem hasn't occurred since the fix.

Same problem. TV worked night before and then would turn on but no picture or sound. Power and OPC lights blinking. I couldn't change the channel or get to the menu.
I disconnected the coaxial cable and the power for a few minutes and then plugged it back in (electric) but left the cable off. I got a message that it couldn;t get a signal. At that point I was able to change the channels. I plugged the cable line back in and everything worked fine... Good luck!!!

SOURCE: Sharp Aquos LC C3242U - Intermittant Sound Switching from Mono to Stereo

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

Check the audio 'output select' under the Systems Settings menus. The output may be set to 'variable'. Set it to 'fixed' so that the audio runs through the speakers.

Unhook the PSU from everything that you can and turn it on, see if it blows anything out. If it does not then you are looking at a non PSU problem. If it does then it is psu. You need to get the schematics for this set if you can.

Have you checked to make sure you don't have a crack on the screen. Static electricity can also cause this. On many large screen TV's this is normal

Setting up sharp 46


Try to isolate the problem.

Try plugging in another source such as a DVD, is there audio? If yes, problem may be with the optimum box. If no, most likely a problem with the TV.

Also, if you are using HDMI with the HDTV box, make sure the box is set to output audio through HDMI.
