VERY GOOD SERVICE.FAST ANS VERY HONEST PRICE .RHAANK HERNAN
 ;
Thanks to this service manual I repaired my old camcorder! The manual perfectly explains how to disassemble the camcorder step by step.
;
This manual is very useful because it presents the technical specifications of the cd player, including the manufacturer of the reader, this helps if you need to replace it. It also displays the settings and layout of the circuit.
;
Manual was a good representation of service infomation for the EWV404. It worked well for my repair.
;
Great quality copy, right what I was looking for, all I need to fix my radio.
Thanks
