buy a universal remote

What could be done is to leave the set Switched ON for many hours even overnight and see how it can change if there is a possible fault on the motherboard, a change of value in electrolytic capacitors.
If there is no result then there is fault in the motherboard and you need to take consensus for an estimate.

Try unplug,replug the unit back like about an hour later for the unit for resetting itself back to factory setting.If getting the same result the unit might have a shorted motor drive for the disc tray.Or shorted control panel on the unit itself.Well,this thing a basic DVD player only wright?If u can tries take it aparts and check out tries to repair it ur self that great.If u tries the shops,not worth it.Trash it.These basic DVD player only are very cheap now.U can get one brand new like $40 dollars.

Sorry, no there isn't much you can do at a consumer level with this player, except, if you still have a manufacturer's warranty, taking advantage of it and sending the unit back for warranty repair/replacement (whichever they suggest to you). It is clearly malfunctioning, beyond user control - send it back as a warranty claim (if you still have one on this model). It won't cost you in repairs that way.

Don't put up with a defective product, send it back - get it fixed under warranty free of charge (if applicable), or the unit replaced (again, if under warranty, free).

It won't cost hundreds of dollars and shouldn't take forever to resolve this simple case. Good luck. This is something the manufacturer should worry about; not you.

Move the remote to another room to test. It is possible a button on the remote is stuck on.

Beyond that , it probably needs to go in for service.

Here you go. This will work with most all universal remote controls. If you don't have the code do the following:
Automatic Programming
With automatic programming, the remote control tests all the codes available on the Code List and assigns the correct code for the selected device. Although this method can be more time-consuming, it eliminates the need to look up codes and enter them manually.

1. Turn off the device with which you want to use the remote control.

2. Press and hold the corresponding button on the remote control
(TV, VCR, SAT, DVD, CAB or AUD) until POWER INDICATOR illuminates. It should take a couple of seconds for the light to remain solid. The remote control is in programming mode.

3. Press and release power button. The POWER INDICATOR flashes once and stays on indicating the unit is in Power Scan mode.

4. Press CHANNEL up or CHANNEL down repeatedly until the device turns on.

5. When the device turns on, press OK to store the code.

Note:
• To exit without storing the code, press BACK.
• T he unit will search for the next code or the previous code if you press
CHANNEL up or CHANNEL down after the device turns on. (go slow you need to press OK when the TV turns on) if you mess up turn TV off and start over.
6. Press any other button. If the device responds, the remote control has been programmed. If the device does not respond, repeat steps 2-5.

Sound like to me you got a problem with the capcitor inside the unit, if its under warrenty it will need to be serviced. If its not I ould be checking capcitors inside to make sure there not bulging leaking or otherwisen ot wroking correctly.

If it's not ejecting or responding to any of the buttons on the unit, or the remote, but is able to play a DVD, the display microprocessor(computer) within your Harman is damaged. For more information, please visit my website at audioserviceclinic.com. Thank you.

Since the unit is under warranty, you can't touch anything without voiding the warranty. This problem could be as simple as a dirty lens. Bring the unit in for repair under warranty.
