How to fix a blue screen

Usually if there are headphones connected, the speakers are turned off.

i have a ouku 7 inch dvd player when evere i turn on the truck the screem turns blue and it has a mute picture that binks on the left side i dont know wht it is can you help me

Just bought THOMSON DV2137 in Australia (region 4) It plays Aus but not US. A small slip in the user's manual gave these (verbatim) instructions. UNFORTUNATELY it isn't working on my player."This unit has been set to play region 4 DVD discs. If you wish to use this unit outside of region 4 territory you can change the region setting by following the instructions below.1) Turn on the unit.2) Remove disc and press SETUP to enter SETUP menu.3) Press VOL+.VOL-,VOL+,VOL-, by order, then press MUTE to enter Region Code setting. [stays in SETUP menu]4) Press LEFT / RIGHT to choose between 1-4 or ALL region."
Perhaps this will work for someone else or will trigger a clue.

On the left hand side of the remote control there is a blue or diferent kind of small sercle round buton (mute) push it once and turn the volume up till you hear the volume.

For the Anti-Theft Passcode if you forgot yours - Turn to player on. Make sure the screen is out. Press and HOLD the MUTE button. While holding the MUTE button, press and HOLD the POWER button. (Should be holding them both down at this time.) After about 12 seconds a new passcode screen should come up. Release the MUTE and POWER buttons. Type in 122164. Press OK. Your passcode is now reset to 0000.

For The E Brake Passcode - Put in a DVD. Wait until you hear the sounds of the DVD. Press STOP twice on your remote. Press 22604 on the remote. Press OK/ENTER on the remote.

Hi If your t.v.has built-in blue screen when there is no signal, then the DVD may have been accidentally switched to progressive scan mode, or defaults to that setting if new. If your T.V. is not capable of displaying in progressive scan mode, you will just get a blue screen. If you have an older tv, without blue screen, then connect it to that, and if you get a black and white split screen when you turn on the DVD, then progressive scan is the problem. Check the manual for the DVD player for the procedure to get out of that mode, and it should then work. If you still have no video, and you are using the yellow composite video jack on the back of your DVD player, then it must be brought in for service. Good Luck!
