Question
Can you please let me know the EPROM reset code (Key sequence) for Samsung Max DX55. Here is a link to the product: http://compareindia.in.com/productdetails.php?id=14521

The system is behaving weird. When I put in a CD and try to play, the CD tray keeps coming in and out, instead of playing. The same thing happens when I am putting in an USB drive, the sound will not come in the video but the picture keeps coming. Everything becomes all right all of a sudden, at times.

Can you please give me the code or let me know where to find it.

I tried to keep the system unused for several days, with no power, but it did not help.  

Answer
To reset just about any consumer electronics products this is what you do:  Unplug the power cord - which you have already done without success.  For this product, unplug it for a full 30 minutes - is enough.  Then power it up again.  The unplugging allows all the internal voltages to discharge to zero. Then, all internal memory units, when powered up again, will restore to factory default.

However, in your case it would seem more likely the problem is related to an intermittent condition brought on by a loose connection or cold solder joint somewhere inside the box.  Bang around with your hand or fist - that may be more fruitful than the reset procedure.

Good Luck,
