How to repair lcd display problem without paying any money.

My multimeter LCD had the annoying big black spot on it. That made me hard to read numbers, so I decided to fix it without paying money because the multimeter cost not high.

This method is not cost you at all because the material I used was in my bin.

All you need:
Time
a piece of paper

See before and after picture below.



Why old LCD display always have black spots?


Because when LCD display exposes to sunlight, the moisture is slowly degrading glue that attaches to mirror foil. If you do not keep the multimeter away from moisture or the sunlight the multimeter's LCD display will be worst until you cannot see anything.

Below is the video that shows you how to repair the problem completely.
