No. You should have a remote control to unlock it. If you wish to buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. They can either give you a genuine remote control to your device, or can direct you, from where can you purchase a suitable one.
To select a proper universal remote control, you should know about the number of digits to its set-up codes. There are 3 digit, 4 digit, 5 digit, 2 digit and even single digit codes, to some brand devices. After confirming this, check the sites linked here. Both the sites have set-up code list and set-up procedure to many popular brand remote controls. Check which brand remote control has set-up code/s to your device brand, and buy that one according to availability? Brand name of the remote control isn't a matter, but it should have set-up codes in its code list, to the device brand you have.
Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its pack. Never accept a remote control, that hasn't both of this.

Check the remote control first. Hide it from the vicinity of the TV and check whether the TVs' panel buttons works properly. If yes, the remote control is faulty. Can't be repaired.

Hi

I have this tv, It is not a internet@TV model it only alows to stream media (Video, Photos & Music) using dlna enable devices (such as the samsung galaxy s) and windows media center.

Hi,

Make sure that you're using the supplied Remote (RMY-906) to control the TV. If so, perform the steps given below to resolve the issue.

• Make sure that you're using batteries which are having enough charge. Try using fresh alkaline batteries.
• Do not use rechargeable batteries in the Remote.
• Ensure that the batteries are inserted correctly with the correct terminals by checking the + and - symbol in the battery compartment.
• Make sure that the Remote is set to operate with the correct functions. On the remote control, press the TV FUNCTION button to re-check this.
• Press the POWER button and other buttons to test the operation.
• Make sure that none of the buttons are jammed in the remote control.
• Ensure that the remote control is being used no closer than 3 feet and no further than 10 feet away from the unit. Try using the remote control at varying distances from the TV.
• When using the remote control, be sure to point it directly at the remote sensor on the device.
• Remove any obstacles that may be in the path between the remote control and the device.
• Ensure the remote sensor of the device is not exposed to direct sunlight or bright florescent lights, as this can interfere with the sensors ability to receive signals from the remote control.
• Try resetting the Remote. To reset the Remote. remove the batteries from the remote control, press every button twice, and then reinstall the batteries.
• Try resetting the TV also to check the operation. To reset the TV, disconnect the power cord for a short period of time (approximately 1 minute), then reconnect the power cord and power on the television.

If the remote control is able to operate other devices (such as cable box, DVD Player or satellite receiver), then the issue may be with the IR sensor on the TV. If this is the case then the TV that will require service. Otherwise, the remote control may need replaced.

Good Luck!
