Samsung LCD TV LE22B450 no sound with external speakers

by ian morrish / October 20, 2009 6:29 AM PDT

I have just bought a Samsung LCD TV. The internal speakers are working when using the digital TV channels. However, if I select external speakers I get no sound. I have connected the RCA cables on the back of the TV to my analogue amplifier (which works with the DVD RCA cables).

Should the RCA output work?

ian morrish,

The RCA outputs should work. You might check to make sure they're plugged in the correct jacks. Does the output specifically say "Audio Out" as noted in #1 in the below schematic?

You might try to toggle the external speakers settings in the audio menu.

If this doesn't work, you might consult the Samsung Customer Service Center in your area for additional troubleshooting.

Keep me posted.

No output RCA connectors on Samsung LCD TV
by ian morrish / October 21, 2009 1:48 AM PDT

I have found out that the RCA connectors on the back of the TV are inputs only. Hence the only solution appears to use the headphones output and use a jack plug to RCA adapter cable. This works well.
Many thanks for your reply.

External Speakers not working on LCD TV Samsung LA32C450
by jrlee31 / August 16, 2010 7:43 PM PDT

i recently bought this LA32C450 LCD TV and HTC350 system which comes with speakers and
a DVD player.

since its a series 4 TV, i can directly plug in my USB.
picture is good but there is no sound even if i select in the MENU > SOUND > and set it to EXTERNAL SPEAKERS

btw the DVD player also has an option to plug in my usb. sound is good, but it can only play
a limited file format unlike the LCD tv which plays almost everything.

640gb seagate external drive: Disconnected error message
by jrlee31 / August 16, 2010 7:47 PM PDT

also i have this 640gb, i plug it in the TV and all the folders pop up, i open my ''movie'' folder
but all of a sudden a ''disconnected'' message appears.

i tried using a 2gb usb and it works perfectly fine. does it have anything to do with the size of my usb??

640GB is a bit large for a directly-powered drive. Use external power.

External audio
by jw650 / August 17, 2010 1:50 AM PDT

The TV may not send audio over HDMI. You need to connect the HTC to the TV using an optical cable. The External Speakers setting is for any RCA-type stereo output.

External audio & USB not working
by jrlee31 / August 21, 2010 3:19 PM PDT
In reply to: External audio

thanks! that's exactly what i did. bought an RCA cable (3.5 x 2) and set my dvd player to AUX.

and the other problem of my 640gb getting disconnected after a while is that it needs to
have an external power to plug it in.

but even the 1 terra bytes nowadays have internal power and are very compact.
and so the workaround i do is to copy the movies i like to watch in my psp that has an 8gb memory.
