Question about Sharp Aquos LC-13SH3U 13 in. EDTV-Ready LCD Television

1 Answer

No sound on four channels while all other channels sound is fine.

About a week ago I was watching and listening to channel 5 (NBC) and I heard a click from the TV, then the sound stopped on this channel. I found the same, no sound problem, on three other channels (12,48,51). While on all the other channels the sound is fine.
I've hooked the TV to another cable outlet in my house and have the same problem on this TV set only, my other TVs all work fine.

You most likely have the SAPNo sound on four channels while all other channels - 1.gif mode activated. Look for a button on your remote or an item in the on-screen menus of your television called MTS or SAP. You want to set this to "Main" "Normal" or "Stereo" (or even "Mono") mode to hear the regular television sound.

If it is in SAP (Secondary Audio Program) mode, as I believe yours is, you may hear no sound or a different audio program. Often this is a translation to another language, such as Spanish, and other times (notably with PBS stations) it is an unrelated audio (often music) feed. On some stations there may be no sound at all with the audio mode set to SAP.

I can no longer receive channels # 4 and # 38 (in Boston), after attempting to reprogram the channels. Why?


In my area, I can't watch anything on CBS, NBC, and some PBS channels even though the transmitters are in Philadelphia and I'm right across the Delaware River in New Jersey. You can try experimenting with antenna orientation or a different antenna or adding a signal amplifier as well as frequent rescanning but results are likely to continue to be disappointing.

I have a Panasonic TH-58PZ700U Which drops channels? Will have the channel one day and the next its gone then it will reappear! Is it the tuner going bad?


I would replace the DG Board. There hard to come by for this TV. I saw one on eBay about a week ago for $75.00 witch is a very good price for this part.

Digital channel 25 has no sound.


First make sure SAP or nothing similar is turned on.

After you triple check that just Contact ILO if it continues for more than 1month. This is a software error.

What state are you in?
What channel is this?NBC, ABC
Have you check this at different times of day?

Might be as simple as you have the SAP or second audio progam turned on, go in to the sound menu of your set and see if it's set to S.A.P if so turn it to Stereo

Get HD Signals but it Says Channels not available


you might have to look for "hidden" hd channels.

most cable companies are broadcasting the local stations unencrypted, so you should be able to receive them and sometimes a few other "basic" hd channels like discovery or tnt.

try googling your cable system, city and hd channels to see if someone has posted a list of channels (eg, 88-1 or 102-1)

Check the signal type. It may be set incorrectly. Change the channel. You may be on a blank channel. Check to see if the TV is tuned to channel 3 or 4 if you are watching a videotape. Check the TV/VCR button on the VCR is in the correct mode by pressing the TV/VCR button on your VCR.
