Hi, Anyone who has a service manual of panasonic sa-ak87. I already had a bad experience with panasonic service technician here in the Philippines. I paid for the huge amount of the cost incurred during the repair which took almost 2 months. After testing the repaired unit I noticed that it is still defective, I was told by the technician to use it for one week and it will return to normal operation. I am also a Technician, but I have no option other than have them repair it because I don't have service manual for reference. Appreciate anyone who have a kind heart to send me a service manual so I can repair it myself. Thanks!
