I had a L1717 come in for repair. It is not an easy monitorto open up. First two screws must removed from what appears to be the stand mounting. These screws actually retain the front bezel, once removed the bezel can be prised off by first levering on the stand and lifting the back cover away from the bezel. The bezel can then be removed to gain access.
The cap problem. The power supply main filter cap 680uF 25V was blown apart. It was a a low grade (low ripple rating) Samxon. The rest of the Samxons gave no indication of stress. Apparently the main cap was not able to sustain the ripple long term (3-4 years). It was replaced with a Rubycon ZL that has great ripple ratings and all works fine.
