Brown Stuff on magnavox 42mf231d

[gorr35]

Can someone tell me what this brown/caramel colored stuff is at the bottom of my power supply board? It looks like burns, but I was thinking that it's a special coating they put on the circuit boards? Ignore the blurriness in the photos....just was trying to give an idea of what i'm talking about. It covers almost the whole board but mainly just around the solder points.

It's left-over soldering flux residue. It can be cleaned off without too much difficulty. I used to use denatured alcohol to clean boards.

acetone and a toothbrush works well too. Its super flammable though and melts plastic, so be careful where you use it.

Board wasn't cleaned well during the manufacturing process.
don't worry about it, won't cause you any prolbems.
