V9 and v10 LA chip syndrome.
It is a well documented fact that the latest v9 and v10 machines suffer from a
major problem. The LA chip has a tendency to die. After it dies, the only
solution to get your machine working again is to replace the chip with an
original LA6508 or a device called LA6508 RII. However, in both cases, it is
quite a hard soldering job. (much harder than to install a chip). The following
can be done to reduce the chances of the LA 6508 chip dying. Again do not
attempt the simple modification unless you know what you are doing.
The original article can be found at

Firstly - the prevention - by far easier than the cure:
1) Carefully lift Pin17 of the LA6508 Chip,
2) Ensure no solder links it to the pad it was just lifted from,
3) Link Pin17 to 5 volts as demonstrated in the picture below.
