My SONY COMBO DRIVE has stopped to read DVD's. But it is still reading and writing CD's. When I took it to some local service center he replaced the lens but still it didn't worked. Now I want to take it to SONY service center. But he told they will charge around Rs.1000 for replacing lens but a new one is available in market for Rs.2100. Can anyone tell about how it costs if repaired it in SONY service center...
