35、So, be careful of electrostatic breakdown during repair of the optical pickup. e Handling of optical pickup Optical pickup 1. Do not give excessive shock to the optical pickup because it is of extremely precise structure. 2. To prevent the breakdown of the laser diode, an anti- static shorting pin i
