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.
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.
