I doubt a main board will correct this, it sounds like LED backlight issues, if you have a multimeter use frame as ground and red lead to backlight B+, you should see 80+ VDC, if you do you have backlight failure and the strips need replacing

Logik are terrible with remote codes and don't really seem to care about their customers, have a look here for an example - How can I set up sky remote to Logik LCD TV? ' Logik tv

Try these 2058, 1893 or 0726.

The real manufacturers like Sony, Samsung, Panasonic, LG etc, do update their lists. But ones who just stick a badge on someone elses device don't seem to. That is why it is so difficult to get a code for 'in house' products like Logik which is a badge of the Dixon Group.

did you try connect the yellow and red wires to the yellow and red

try turning off AND unplug for a couple minutes! USB may have pulled power down to start the switching noise. Try usb again and if it does it again then I wouldn't use that usb anymore.

try e-bay, or google the make to find a on line guide to download
