MSI 6340M ver 5

Hi

Just eradicating dead caps on my motherboard. All caps are Lelon brand.

Count on this board is:
8 off 1000uF 6.3V
7 off 2700uF 6.3V
3 off 1800uF 6.3V
3 off 1800uF 16V

I tackled the 1000uF ones first - they are the ones that are visibly blown, either the rubber seal at the bottom or ruptured at the top. Having got them out, one was open circuit entirely, and the rest measure between 15uF and 150uF with several ohms ESR (at 50Hz!!) and 1mA leakage at 6V.

While waiting delivery of the other caps, I've reassembled the system, and it is already MUCH more stable.
