Try going to Game Master at Bukit Panjang Plaza? They fix your
psp at a rather reasonable price. In case you do not know how to
get there, go to the Chua Chu Kang MRY, alight and transfer to the
LRT service. Take the LRT to the Bukit Panjang LRT station and
alight. Bukit Panjang Plaza would just be a 3 mins walk from the
LRT station. You would not need to worry about spotting the
Building because it is visible from the LRT station itself.
