My lens has been acting up for a while and recently it like died almost completely. I took it to a shop and the guy checked it out and after a few days said I'd need to get a replacement. When I told him I had just gotten a new disk drive this January he said it could be due to the voltage fluctuations. Is he right? Because the light does come and go a lot at my house but it doesn't fluctuate :s he also said I should always keep it connected to a stabilizer is he right?
