i had purchased Aiwa portable DVD Player XD-DW1 from singapore. the machine is being used in india. unfortunately the lense of that machine went bad and i had to replace it with another one. after installing the new lense my players plays the discs with jerky pictures and frame jumps. the technician at my place says that he requires to do some settings from remote control to correct that fault and the service manual is not available at his place. as the player is in remote corner of india and can not be transported to service centre i need the service manual in electronic form or any hints or solutions to this problem. any help will be appreciated. thanks in advance.
