Sony CCD TRV-238E camcorder has two issues, first, a wire in the harness( PD-124) is almost cut, which causes bad contact in the LCD panel, I've tried to used a sort of glue to fix it but without success, soldering the two parts is almost impossible ( see picture), the area is too tight.
Second, when the connexion for standard flexible are cut it is possible to scratch the two parts and connect them with extension wire and welding, but in the case of the CONTROL KEY BLOCK's flexible which is used to connect the CONTROL KEY BLOCK to the mainboard, connexions are not made of copper! (carbon maybe, trying to polish will destroy them!), actually, they are worn out (see picture).
Because these spare parts are no longer available in my country, please I need your advice to fix harness and CONTROL KEY BLOCK's flexible.
