As most current designs of such devices, you can force a full hard reset on the unit/system by unplugging it from the mains for a couple of hours (or overnight).

Thereafter, pls post back if problem persist and will work form thereon.

    Hi 4z4jt,

    A couple more to try:
    1. if you can go to Setup/Others/Factory Setting. PW is 3782 and press Enter to reset; or
    2. press FF Search and Skip Prev. on the front control panel (not on the Remote Control) to return to factory settings.

    If it would seem that no external action is corrective of your concern, perhaps it maybe because of an electronic fault within the system.

    As BFixed has responded in your other post, component(s) may be defective. Most DVDs are internally powered by at least two (2) voltages: 12VDC for the motors and 5VDC for the logic circuitry. Based on your other post, you can only read 11.5 & 2.75. The 11.5 would be acceptable but the 2.75 would not be. A you were able to test the voltages, I am assuming that you are familiar with electronics circuitry and components. Please check where the 2.75 came from. It would be normally from a high current regulator, 3 or 5 pins, you need to check the input voltage or simply wing it from there. The voltage should be higher at the input stage and constant/regulated 5VDC. As BFixed suggested, a failed/bulging capacitor in the power supply can cause the voltage to dramatically go low which could probably account for the orange/red/green leds.

    Of course the best would be to have access to a full service manual or at the very least a schematic diagram. Unfortunately, I luck out googling for one. Though I came across a general purpose trouble shooting and repair guide for CD/DVD players here which may or may not be of use to you.

    Alternately, if the time frame required to even initiate a decent repair plus possible repair/parts replacement cost, it may be more economically reasonable to consider the replacement of the unit.

Remote won't work but can manually operate

you do the camera tricks just to ensure if the infra red sensor of the remote is working. get a digital camera turn it on,then get the remote controller. press any button at the remote controller pointing to the digital camera, if you see a light at the display of the camera then the infra red sensor is good but if no light either the sensor is worn out or the circuit was defective.

Turned progressive scan on, can i turn it off without being able

Try these methods for resetting the scan on your dvd."To reset the VIDEO OUTPUT, turn Off the player, turn back On, open the disc tray and press and hold the Stop button on the player for 10 seconds to reset the scan mode." The Reset procedure doesn't seem to work on all versions but you can sometimes get a usable B&W picture allowing you to get to the menu and change the settings by connecting the composite video input of your display to the Red Pr/Cr or Green Y component output jacks on the rear of the cabinet.
You can also go into the Menu and set it blind with the following key presses on the Remote:
1. With the unit Stopped, press Setup.
2. Press Enter.
3. Press the Down Arrow 3 times.
4. Press the Right Arrow Once.
5. Press Enter. Hope this helps you with your problem

Progressive scan mode

THis one should be easy--just read it in the manual--reset your video mode by removing any disks from the player, close the drawer, and then press and hold the "stop" button for five seconds. The green power button should flash red and back to green. Hope that solves it.

Not sure, but I believe the 2.75 volts you have should be 5.0 volts.
May want to check capacitors on power supply.
The output connector on the supply may also be labeled with
the correct volatges for reference. COnstant orange light may be
indicating the +5v is low.

Holding the Reset button for 60 seconds didnt help!!!!!!

Unlike the suggested solution to reset to factory settings by pressing the stop button on the DVD player itself with the tray OPEN, in my case I succeeded only with the tray CLOSED (no DVD inside). The light flashed to red e back to green and it was done.

There is an error in the manual. In order to reset to factory defaults, turn on (with no disc inside), DO NOT OPEN THE DISC TRAY, just press the stop button on the player for 5 seconds (some solutions say 20 seconds).
