No audio on sharp lc32sb24u 32'' TV

We turned our tv on this morning and although there was a picture, there was no audio. There is a box that appeared in the corner of the screen that says ''Cable Analog'' and has the word ''Mono'' flashing back and forth in red and green.

SOURCE: audio box flashes on screen {mono/stereo}

Nope. I found out what the problem was...cable box settings. If you just drop by the office and pick up a cable box without them installing it for you, be sure to get instructions on how to set it up, because it is not set up for HD. That's what my problem was...maybe won't apply to others, but just passing it on. Thanks.

How many times is the POWER LED blinking? (Don't worry about the OPC LED).

1x = Bad inverters/lamps
2x = Bad Power Supply
3x = Bad Main Board

Either way, there isn't anything you can do to fix this, you need to contact Sharp to have your TV serviced.

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

SOURCE: my sharp 32 lcd keep flashing the channel and audio mode

If your receiver came with audio video cables, hook them to your receiver and to either input 1 or 2 on you flat screen. These inputs support audio video. This will stop that annoying flashing between mono and stereo.

SOURCE: Audio with digital channels, no audio with analog channels

I was getting a constant mono setting for all channels with no option to set it to stereo. I called Sharp, and they said that in order to receive stereo sound, you cannot use a standard coaxial cable. You need an S-Video or HDMI cable. This not only resolves the mono audio issue but also resolves the analog (vs. stereo) issue. Hope this helps!!

Which roku do I get for a sharp model lc32sb24u

I always get the 3 because it has the most features. I have three of them now, and they all work great. I think any of them will work with your tv as long as it has an HDMI input.

My LC32SB24U Sharp TV has died after only 18 Months!

Well, the power supply module will have to be the first place to look. Most LCD TV breaks down after about 2~3 years, one of the reason is that the minute is plugged into the wall outlet, the power supply and the processor will be running 24/7 even the TV was never turn on, they will be subjected to power surges, spikes 24/7. I always completely turn off my AC power surge suppressor outlet to OFF so there will be no power to the TV when it is not in used. Parts for your TV:

Try turning off the tv and unplugging it for one minute, if that doesnt resolve the issue, look into gettnig a converter box, or a signal booster to help. The tuner's in those SB model sharp televisions are not worth a penny and they need a very strong signal to be able to interpret all of your stations without problems. good luck 2 u
