    thanks for all your comments but none of these help, there are no external speakers connected to the tv. I just pulled it out of the box and connected it to the cable box and the sound is very low. I've tried all the settings in the manual, but must admit I am just pushing buttons... nothing seems to work. I even tried connecting external speakers, but no sound come frm them at all. It's a digital tv but I can get it to change from the analog mode... even though I try to set the digital option....

    Once again thank you all for your help, I decided to disconnect the cable box and all the other connections (video,etc) then i found an S-video cable, I removed the cable that comes from the cable box and just used the Svideo cable and changed the input settings from TV input to Input 1, and what do you know, the sound came thru loud and clear. So I dont need external speakers or have to return it after all. YAAA for me.. Buts thanks everyone anyway..... I will post again for help on how to hook up some logitech speakers and woofer to the same tv, but later....

Sound amplifier circuit may be faulty. You need some experience for troubleshooting it. Better take it to an authorized repair station.

The sound problem is internal to the set, the main board has an audio failure. since it is new out of the box, call sharp to have it serviced under warranty or return it to the store you purchased it for replacement. this is nothing you have done, it just is a failure of the components or software of the main board. sharp may even have a software up grade to solve the problem. so call them first.

I think that you just have a defective tv and should return it and get a different one.



Things to try before returning it are.

1. Pressing audio on the remote to toggle between Mono, Sap, etc. settings and see if any of them improve the audio

2.

3. Download the manual here -> http://www.retrevo.com/search/v2/jsp/downloadPage.jsp?doc=202375cfd4595c46604e771e6c8300db&q=Sharp+LC-37SH20U&e=1

refer to page 19

Let me know what you try and if none of the above works, let me know and we can try further options

thanks

Consult your user's manual. There are various volume settings that can be applied. Maybe it is set to a soft low tone.

HI,

Try unpluging all the cords from the back for 4 hours and then plug it back this will restore the factory default settings and also make sure that all the connections are tightly plugged in.

Goodluck,

Hi my tv wont turn on. No picture. Just a sound like a buzz. just a black screen.


Hi,
Model number and brand of tv will help us to understand what kind of tv you have and what could be possible reason of problem for buzz sound when you turn it On.
Without tv model number and brand info, it is not possible to suggest any thing because many kinds of tvs are being used.
Thanks.

The green light on front of tv keeps flashing and tv wont turn on


Howdy,

The green light blinking indicates your TV has a problem. The problem is that each Brand of TV has different codes and with out the Brand and Model number, I can not help you at this time.

Please, count blinking sequence. Model number will be on back of TV.

Recap : Provide Model Number, Brand and Count Blinks.

First though; unplug TV from power source for 3-5 minutes then plug TV & box back into a/c outlet.

Good Luck, BIG IRISH.

BROKEN SCRIN ON PANASONIC MOD,C42PX6U CAN BE FIX ??AND WHA IS TE PRICE ..THANK YOU


hello, if you want to fix this tv. the screen replacement is as much as a brand new tv. i can suggest you find a same model "as is for repair" tv on a auction site. then have a service tech exchange the screen for you. it isnt easy to do but if you have a replacement screen then they wont charge you for the part and it will be cheaper to fix.
check this link i see one "as is 42PX6U"

http://cgi.ebay.com/PANASONIC-TH-42PX6U-42-PLASMA-FLAT-PANEL-HDTV-AS-IS-NR_W0QQitemZ380088249128QQcategoryZ3320QQcmdZViewItem

this is the easiest way without costing you over 1000$ for a new replacement screen.. search around for a repairable tv and have a service center tech exchange it for you..

good luck hope this helps
