Hi guys!

Just recently I connected a 22' Samsung LCD TV to my Acer Aspire 4720 laptop, my main goal was to view streaming video and movies from the Samsung LCD.

I connected the laptop to the LCD via a serial cable great picture but this had no audio, so I hooked up an RCA connection cable to the LCD and plugged the other end to the laptop's headphone jack, but alas still no audio from the LCD. I only get sound from my laptop speakers.

Suggestions on how to get my laptop's audio from the LCD TV will be most welcome and appreciated!

Best regards,

Are you using the proper converter at the end of the RCA jacks? The RCA jacks' coaxial connector will not fit into the sound output port normally without an adapter.

If you are using the proper converter, make sure you are hooked up to the A/V In ports on the back of the monitor and not the A/V Out port.

I'd suggest you check the Samsung website.
I just did a random check and they had a pretty comprehensive troubleshooting guide with a step by step for no sound issues.
Since we don't know which model you have it makes it difficult to assist.
Here's the website link I was looking at http://www.samsung.com/us/consumer/tv-vide...agetype=subtype
It shows 3 models of 22" LCD TVs with PC connectivity. Their are various options in the TV menus to use other sound sources or disable the internal speakers all together. Once again depends on the model. I didn't notice a RCA Audio in for a PC except on one model, all had standard audio cable inputs for PC. Did see AV in with RCA plugs and know that that may not work as a audio source except when TV is set to Aux/VCR as the source. With a video playing via the PC you could try changing the source on the TV to aux and see if you hear sound.

Basics to check;
With headphones plugged into the same PC output jack do you hear sound?
It is possible that the headphone output isn't enough to drive the speakers in the monitor to a audible level.
Does LCD TV normally have any sound (such as in TV mode)?
Have the cables you're using been tested good?

Dear ERic and Koinos,

Thank you for taking time out to provideme with your insights on my problem. I did some double checking on the connections and found an audio connection for PCs, so I got myself an cable that would match the output of my laptop and that on the PC.

At first I was stunned as there was still no sound coming out from the LCD, I backtracked the connection and found that the cable wasn't plugged properly. I reconnected and voila! sound was now coming out of the LCD.

@ Koinos the model I have is the series 3 version of the 22' panel that they offer.

Once again thank you guys and regards!
