Greetings. It's been a while since I've been to Computing.net.

I've owned a Toshiba Satellite C650 for a little over a year now. I bought it in August 2011 before I moved up to college. I took the cheap route because I was still using my desktop as my primary machine. I've since sold that computer and I'm learning the ins and outs of computing on a budget laptop.

I just started using my TV (19 inch Sansui HDLCD185W) as a monitor using a VGA cable, but I've run into a problem with a humming noise. Some googling revealed that this is not an uncommon problem for this set as it is fairly cheap. The humming sound is somewhat loud, but very bothersome. It continued to hum when the TV was being used for viewing as well. The humming disappears entirely when it is muted or the volume reduced to zero. This isn't a huge problem because I'm using onboard sound for my laptop, and I plan to run my stereo speakers through it as well when I get the cables, so I'm not super concerned. However, I'd still like to troubleshoot and hopefully resolve the humming problem.

Thoughts?

Thank you.

A bad hard drive or fan wouldn't stop when the you mute the sound. That makes is sound like a bad connection or bad sound chip.

This is a TV Question and not necessarily a PC problem however, it could be that you have speakers attached to the TV or an amplifier with speakers, or that an amplifier with speakers is near the TV and is causing interference, or that you have too many appliances on the one powerboard and the TV is straining get power.

Solution? Don't put an amplifier too close to the TV and use a different powerboard for the TV power plug.

Thanks for the suggestions. My stereo is sitting about 7 feet away from the set. I will move it and see what happens. I'll also try using another powerboard.

I'll let you know how it goes.
