Hi Barb, Please have the speakers checked.

To reset it, you have to enter its service mode option. To get it, you have to download its repair manual. User manual will not have this detail. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter". http://electronicshelponline.blogspot.com/ Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

You can not program a remote that comes with a device to operate that device. It will always just work. Check the batteries, make sure they are in properly and try to replace them.

TRY CONNECTING THE RCA JACK (RED,WHITE) AUDIOINPUTS. MY GUESS IS THAT IT WILL WORK THAT WAY,AND IF IT DOES CHECK ALL AUDIO SETTINGS ON BOTH AMP & TV PCM digital audio / LPCM digital audio (LIMITED)MAYBE BAD HDMI CABLE. SEEN IT SEVERAL TIMES B4

Easy peezy...just press TV on your sky remote,now hold select and the red button until it blinks twice,after it blinks twice enter this code ...1430....it sjould blink twice again,now press standby,it should turn your tv of,if it does press select to save these settings,it should now control your volume too,let me know if this helps

give me more clues ???????????

The set may not be at fault. If you are on cable some channels are still in anolog and some are digital. if you are on a nolog channel the picture will look preaty bad compared to the digital ones.

I think this is what you are looking for. Also PS3's come with the same type cable I believe.

Any luck? We bought our tv (same one) in March of last year. It is doing the exact same thing. Time Warner has already came out and switched out the cable box and cables. We have a tv tech coming soon (contracted out from Samsung, of course...) Problem persists...

its not hard as you think you should return it just the way you pulled it out because it has a polarity negative is commonly marked in the capacitor but you must have the proper tools soldering iron and solder ******.

You may have bad DC filter caps in the power supply, that will be the first place to look.
If you are going to DIY and have proper tools and know safety precaution then please read on:

Up front, i copied this from another site, so kudos to the OP there if this works for anyone...

Hi,
This same problem had been bugging me when I bought my LE37B650, everyone suggested adjusting the delay time on my AV amp but unfortunately mine does not have this function.

Anyway I finally fixed the problem using the following steps

Before you start make a note of your menu settings as you will have to reset them after this procedure

Turn off the TV then press Info -> Menu -> Mute in sequence then turn the TV back on again. This will get you into the secret Service Menu. Go straight to the AUDIO page of the menu. Don't be tempted to fiddle with things in service menu cos you can end up in a right old pickle!

In the AUDIO page you willl notice that there is a time delay set for the internal speakers of 100ms but for some reason this is not set for the external output so all you need do is dial in a 100ms delay there and that should sort the problem. Well it fixed it for me.

Note that as soon as you enter the service menu, all your other standard menu settings are lost and the screen will be set to dynamic for some reason so you have to go through and change everything back after you have done this.

Hope this Helps

This would suggest that you CAN fix the problem with an analog amp.

Also interested to see if a 2 year old thread is alive!

either a bad controller board or bad panel,if lines are not intermittent bad lcd panel

Hi

A common fault with this model is bad capacitors in the power supply, Remove the back from your tv and look at the power supply for bulged / swollon capacitors on top, they may even leak a brown like substance and should have a value of around 1000uf 10v
Change these where possible with the same uf but higher voltage lets say 1000uf 25/35v
Hope this helps
