Why is there no picture or sound on my Denver MT-779DVBT Portable DVD Player?

If you're not getting any picture or sound, first, make sure the A/V cables are securely connected. Also, verify that you're using a compatible disc format like DVD, DVD-RW, or AUDIO CD. Avoid using scratched or dirty discs, and ensure the label-side of the disc is facing up. If viewing with a TV, confirm that the TV channel is set to VIDEO or AV. The pick-up lens of the DVD player may be dirty.
