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.

From Cleggsan:

"This seems like a corruption of the software codes in the EPROM memory units inside the unit.
Here is a reset procedure; it may cure this problem:

Unplug the power cord of the set for at least 1 full hour.

After one hour, reconnect and power it up.

This should clear any corrupted software and restore it to normal operation, again.

Hope this helps."
