I received a good service manual, with good resolution. Improve the instructions for the purchase because they are not well understood.
For the rest, so good.
Thanks Angel.

Very good documentation for the Grundig 2077 model (as well as similar 800/900/1000 series radios). The first two pages are a summary of reception specifications and output capability. The third page is the tuner dial indicator and dial cord routing diagram. the final ~5 pages are the schematics for the various models (including 2077). The scan quality of the schematics are good, adn can be easily read if zoomed in. The documents are in German, not English as stated. It would have been nice to have the tuning sequence and settings, and some trouble shooting materials... or component and wiring map.

Very good detail, all pages clear, exactly what I needed

Excellent service, and just what I needed to service my TU-7700. All pages of the manual are clear and easily readable.

Use the InfoLITHIUM battery. Use a compatible disc with the camcorder. Clean the disc with the supplied cleaning cloth. Use a compatible disc with the camcorder. Remove the disc, and insert it again after one hour. Remove the power source. Reconnect it again and operate your camcorder again Retry turn the power on by the power switch. If it does not recover, check the focus MR sensor of lens block (pin ql, wa of CN2101 on the VC-439 board). If it is OK, check the focus motor drive IC (IC2104 on the VC-439 board). Make EEPROM data correct value. (Note 1) Inspect or replacement of the mechanism deck, IC (IC4301 on the MD-129 board) and drive block Inspect or replacement of the codec IC (IC3001on the VC-439 board) peripheral circuits Inspect or replacement of the Audio Codec IC (IC3001 on the VC-439 board) peripheral circuits Inspect the lens block zoom MR sensor (pin qh, qk of CN2101 on the VC-439 board) when zooming is performed when the zoom lever is operated, and the zoom motor drive circuit (IC2104 on the VC-439 board) when zooming is not performed. Check both C: 32: 60 and E: 61: 10 of the self-diagnosis code.

Inspect PITCH angular velocity sensors (SE6801 on the CM-069 board) peripheral circuits. Inspect YAW angular velocity sensors (SE6802 on the CM-069 board) peripheral circuits. Checking of flash unit or replacement of flash unit. (Note 2) Inspect the flash memory (IC3101 on the VC-439 board). (Note 1) Inspect the EEPROM (IC2602 on the VC-439 board). (Note 1)
