I have a Hitachi Camcoder
Well you are indeed going to have trouble obtaining that. You see this is one of us engineers biggest problems. Spare Parts.
Usually a manufacturer doesn't "Hold" parts for more then 12 months.
Plus one needs a Service manual,or part manual, in order to obtain the Special Parts Number that identifies that particular part to the manufactures parts provider. Without this number it is almost impossible to obtain the part.
The ONLY shots you may have is AL Try looking, Asking on eBay.
Or Contacting Hitachi, and you may need to try a few, around the country,and ask for a Service Manual, I have searched on the net, but cannot find any.
Then if you locate a manual glean the parts number, and then go back to Hitachi, and try to obtain the Part.
Or maybe a better bet would be to contact an Hitachi, local or head office, and ask for a referral to an authorised service center, and let them attend to it, they will be able to actually GET spare parts, original ones, also they will get them cheaper too.
Of course before you allow an repair to proceed ask for a "Quote" before hand, this way you know whats what.
