Over the past few years, DVD players have dropped in price by 90 percent or more. Once costing over $1,000, you can now buy one for under $100. Or you can buy a combination DVD/CD player for less than the two units separately. And you can get a DVD player installed in a computer. But what do you do if your DVD player needs fixing? Let's take a look inside.

How Does It Work?

A DVD player is an electronic digital video device. A small motor rotates a flat plastic disc that has been stamped with a digital code representing video and audio data. The data is sent to and translated by a television. A DVD player operates similarly to a CD Player .

What Can Go Wrong?

Like CD players, DVD players are relatively trouble free. You can clean the machine, replace cords, and replace faulty motors, belts, and trays. More often, problems with DVD players are caused by faulty DVD discs, either damaged or dirty.

Fix-It Tip

A good investment is a CD/DVD repair kit for polishing out surface scratches, available at larger stores where CDs and DVDs are sold.
