Sound and video freezes

I've been playing a lot of YouTube videos recently which has caused the fan to whir a lot more than usual. Then I noticed the audio on my earbuds quit, and when I tried to adjust the volume on the keyboard controls the onscreen sound display had a line through it (the "no" diagonal line) and I could not adjust sound.

Now, when I first turn the computer on, sound and video work fine for a while, but after a while of use, the audio quits. The computer appears to run fine other than audio cutting out. This isn't just with the earbuds, but the internal speakers as well.

When this happens and I'm watching a video, the video AND audio stops playing.

If I'm listening to a CD or to iTunes when the sounds goes out, the countdown timer on the song also stops, as well as the audio output.

One other thing I've noticed is a slightly yellow discoloration (about 1 1/2" diameter) on the white plastic on the bottom of the computer, right under the 1,2,3 keys. In the center of the discoloration, there is a very small (dime sized) area where the finish has actually chipped off. No doubt this is from heat.

So.. is this computer "done for"?

If repairs would be fairly costly, I'd prefer to sell it as is. What might it be worth as it is?

The first thing I would do is open it up and see if it needs cleaning. Inspect the boards and see if I could locate the problem.

I've never opened the MacBook except to swap out hard disk drives. Perhaps I should venture in there deeper. Unless it takes a seasoned computer technician's expertise to do so.

Should I really open it up all the way? If I had good instructions and it isn't too terribly difficult, I'm confident and willing to give it a go.

Look at the overheated spot. What does it correspond to on the inside?

by

The overheated spot is directly under the 1,2,3, Q, W, E keys area.

Without busting the computer wide open, that's all I know so far. Is opening it up not too big of a job?

by

The overheating appears to be in the area of the I/O port, where the power comes in. See if this looks like the spot?

Hi DHart, welcome to iFixit Answers !!

First you should download iStat Menu for Mac and monitor the internal temperature of your MacBook during an intense youtube session. Post the readings here.

Second, that could sound strange but try to repair your permissions via Disk Utility software located in folder -> Applications -> Utilities or with Disk Utility on your installation disk (recommended by Apple). I resolved a similar sound problem with this simple procedure.

I did repair permissions and installed a diferent hard disk drive. Issue continues to occur.

I would check the overheating issue. Let us know the temp you get on intensive job.

Check to see if any red light is coming out of your headphone jack. I have had a similar problem, and it had to do with dust triggering the optical audio jack. The fix involved sticking a toothpick in the audio jack and scraping around inside counter-clockwise, I think.

I did blow out the jacks. Issue still occurs, unfortunately.

For what it's worth, there's apparently a switch inside the jack. As I understand it, blowing it out is often not enough.

Sterling... OK, I'll try routing around in there with a toothpick. Thanks for the suggestion!
