We bought a vlf c-scope 950D which was not operating at all and we found that two intergrated circuits were missing. We need the schematic or service manual of it in order to repair it. Please DO help me!!!!!!!!

Attach a photo from pcb so to see who ICs are missed and i"ll tell you the type of them. -
Check if there is solder on the reverse side - they may be for a different model??Comment

We bought it second hand, the detector was fully operating but something happened to it and my father gave it to a technician to repair it. A month after my father got back the device, with still no operation at all. That's why we need the schematic diagram or the service manual to repair it.Comment

at one repair russian forum I detaily described a problem, did give full ICs part list, commented with board photos. when I did not get good respond, although the thread was responded, I thought to ask Service Manual. in one moment my thread was re-moved from main forum in dust hole forum. after 3 days the thread was deleted by moderator.
happened I did violate forum rules because I ONLY asked the service manual...
please make what Geo asked you. PCB pics at sunny day in hi resolution, both sides.Comment

Dan, if yours has the blue blobs like in geos pic try checking them. These tantalum caps can be unreliable long term.
do you have a multimeterComment
