Phillips Portable dvd PET824 won't play dvd; no picture or sound

follow this steps, and fix it. Merry Christmas.
However you must sure if you device can play any CD/DVD.
Does not play disc

1. No disc. - Load a disc into the tray.
2. Disc has been loaded upside down. Place the disc with the label side up.
3. Disc region code does not match region code of the player.
4. Disc type is not the correct type to play.
5. Disc is damaged or dirty. Clean the disc or try another.
6. Moisture may be condensed inside the unit. Remove the disc and the leave the power on for one or two hours.

If you look very closely, is there an extremely dark picture, or a solid black screen? If it's an extremely dark picture, you just need a new backlight. If it's a black screen, you either have a bad connection (broken, shorted or unplugged cable), or need a new LCD. Let me know, and we'll go from there.

My guess would be that the switch inside that the tray hits to tell the dvd player it's closed is broken.

If making a noise the issue could be in the mechanism and or the motor that spins the disc---unless it is a real expensive and fairly new unit it would be better to just replace it.

Hello
Put a video CD and see whether it reads and plays. If it also does not plays, or if video CD only plays and not DVD; in both cases; the Laser Pickup Unit is faulty and should be replaced with same type and number. OK.

try cleaning the laser lens with a swab and some 91% alcohol GENTLY Then dry the lens with a swab and try again

I put A dvd in my phillips dvd player dvp 5140 player and it say put in a password i never put a password in it how can i get rid of it

It's not operating perfectly. It doesn't always load the DVD on the first try. But once it's loaded, it plays through okay. I just kept moving the laser unit back and forth and cleaned the lens as recommended. I got the unit to where it would keep trying to load the disc and finally it recognized the DVD and started playing.

This may be due to a bad contact in the connector. If you unscrew and remove the back cover, there is bunch of wires coming from the LCD with a male or female, I forgot, connector on the end, which plugs into its counterpart on the main board. That connector may not be fuly plugged in. The chance that this is indeed the case is no more than 10%. Unfortunatey it looks like this the electronics failure - 70% or LCD itself - 20%
