• Switches off after a short time. Take-up reel jolts. (VN7500 tip from NIKON)
• The plastics which surround the CRT may be melted by the sunlight.
• Mechanism jammed. intermittently.
• Failure of flexible membrane may result in various faults.
• Camera switches off again immediately since the supply table is not driven.
• Unstable picture. Oil on the tape or on the tape path may cause picture distortion, head clogging, tape eject or no drum rotation.
• Service information. The CCDTR805E is equipped with the guide rail base (1) assy P/N A7040251F.
• Noisy audio. A rustling sound or sound interruptions may occur when using mp tapes. (extract of circuit diagram attached)
• The take up reel table does not rotate with an inserted cassette.
• Does not accept cassette. Mechanical crunching noise.
• Tape jams. (NIKON - VN7500 information)
• VCR skew problem in certain mode. Skew may occur at the noise bar during CUE/REV or pause.
• Intermittently does not accept tape.
• Mechanism loads halfway without cassette, rewinds a few seconds and stops.
• Caution light on when loading.
• Misindication of data code and time. When switching from REC to STOP while the time is indicated on the data code display, the 12-hour format on the EVF or the LCD may change to the 24-hour format (e.g. 15:00 PM instead of 3:00 PM). (+ extract of circuit diagram)

• Intermittently dead. (picture attached) (service info for NIKON -VN7500)
• No mechanical operation. The bulletin illustrates a procedure to be followed to determine if the T reel and S reel need replacement.
• Does not load tape. No eject. Fault occurs intermittently. .
• TG1 arm falls out.
• Mechanical noise. Mechanical noise during rew, or noise captured during REC.
• Irregular loading. The cass tape may stick to the drum resulting in the tape being ejected. (last emergency - drum pg error).
• Ticking noise from mechanism in all modes. (NIKON - VN7500 information)
• Pixel repair for LANCLink Interface. (VN7500 tips)
• Transport noise in FF, REW and PB.
• Destroys under side of tape.
• Service manual amendment. Flange back adjustment.
• Intermittent transport.
• No eject. Powers down with caution indicator blinking. (VN7500 tips)
• Faulty data communication. No SP/lp distinction in playback.
• No eject.
• When in REW, drum reverses. When loading the drum slows down, then the tape is unloaded.
• No eject intermittently. Capstan motor possibly doesn't rotate. Intermittently ejects. Capstan motor not rotating.
• No unloading or ejecting of tape.. Although the unloading operation during eject is normal the cassette compartment does not rise.
• Eject inop ( TG-1 lever comes off it's guide ) (VN7500 tips)
• Switches continuously from SP to LP.
• Drum runs at high speed when power is applied.
• Unit will not close door. When applying power, mechanism ejects OK, but will not set back to load/unload state.
• No mechanical operation. The bulletin illustrates a procedure to be followed to determine if the T reel and S reel need replacement.
• Damaged cabinet. Loosened grip belt.
• Eats tape.
• Motor noise. Drum motor noise may be recorded by the microphone. (service info for NIKON -VN7500)
• Cassette compartment won't rise
• Cassette ejects but new cassette cannot be inserted.
• In playback picture is broken from top to bottom. Vertical trembling of a part of the picture.
• RK gear goes under supply reel in REW and breaks.
• Extension cable J-13 info.
• Does not load tape. intermittently.
• Damaged CRT or viewfinder. The EVF cabinet surrounding the CRT is damaged. The damage is patches of plastic having been affected by surface heat.
• During playback alternating dark/bright vertical bars appear on picture. The symptom is most obvious on dark passages. (VN7500 NIKON repair tip)
• No tape loading, loads ok without a tape. No drum rotation.
• Loads tape then ejects immediately. (VN7500 tips)
• Mechanical noise. Mechanical noise during rew, or noise captured during REC.
