Hi Thanks for using FixYa. Error
code C31:23 means that the FWD back tension value is too high due to grease
sticking out of the "Gear Assy, Gooseneck", adhering to the band of
"TG2, Arm Assy" or "Table Assy, Reel”. First remove all
batteries and then shake the camera hard (or alternatively hit the bottom hard
with your hand -at your own risk-), this will remove the error. If it still
does not then you have to give the camera a couple of hard taps, on the side and base. Please do rate the solution if
the issue is resolved or post a comment for further assistance. Thanks Rylee
Poor contact of drum motor connection(flexi found at the upper part of the drum assy). Solution, disconnect this wire from the connector and cut 1mm from the end so that it will make a new contact. WIre will be shortened a little bit but it still can work this way since this flexi can not be ordered alone, it comes complete with the whole drum assy. Good Luck
dear try to change the battery ,if still it doesnt work then ...i need nt tell you that ur camcorder is dead ,.. and for that ..... their are circuit protector (commonly known as fuse) in DD board which supplies the power to the VC board .. and for repairing the DD board to need to take to the service center as their is allot minor soldering work to be done on the board.
This is for Sanyo VPC-HD1, VPC-HD1A black screen problem how to clean auto iris unit.First you have take apart camera : remove 4 screws from right side (in battery compartment) 2 screws from bottom, 2 screws from top (there are different short one is from rear) and last screw from front,
now pull left cabinet from top and take appart.Be carefull !!! there is flash capacitor you need to discharge it before doing anything else.You can discharge with 1Kom 5watt resistor .
After that remove 1 screw holding speaker, disconnect and remove speaker.Now pull power board PW-1
there is a screw holding lense ring remove that screw, disconnect 2 connectors from lense assy
(from ccd just pull, from lense unlock and pull flat cable now you can remove lens assy.
Next remove 3 small screws holding heat sink (rear of lens assy) after that remove spacer (black tape from top of lense and another small tape at rear top of lense. Now you can see 7 white screws and 1 black screw remove all of them.Black screw holding iris unit.Now carefully lift zoom motor focus motor 2 sensors nd filter assy and iris unit they came out all together.Next thing main thing you have to open iris unit it is easy to do with sharp blade on the edge of iris unit you will find 2 locks holding
metall casing of iris unit put blade between metal and plastic case and pry to remove metall case.
Now you will find iris 2 blades there are different you need to remember wich is wich.Now carefully remove both blades (they might stick to each other because of grease) and place them into isoprophyl alcohol after that put them on to napkin fold napkin so blades are inside and dry them
you also need to clean iris unit where blades are going from grease and also clean zoom motor and focus motor shafts to remove grease. Now put everything back together and i hope you can do that.
Problem seems in power supply section at VC-516 (main board). If you know how to open and repair it, just check Fuses at VC-516 board and these are located near connector coming from battery / dc-in jack area. One fuse is open in this case.
