Sweet! I won the item on eBay and couldn't adjust the geometry or even keep a steady picure. This guide has the full schematics (not available anywhere else as far as I could tell), and was a bargain for the wealth of knowledge it contains. I hooked it up to my testing equipment, tweaked a few potentiometers and got it playing videogames in no time. Thanks!

It was just what I need to fix my old BMW's CD player. Very convenient also. Thank you.

Great Manual! It contains all the wiring schematics and mechanical exploded views that are essential for service and repair. I was surprised I even found this for such an old machine. Only wish I knew of this site many years ago.

Great manual very clear copied. You are making an incredible job. I appreciate a lot the rapidity and your efficiency. Thanks a lot

Abgleich / Alignment
D Abgleich
1. Chassisplatte
Me�geräte: Tastkopf 10:1, Farbbildgenerator, Spektrumanalyser oder HF-Millivoltmeter Servicearbeiten nach Austausch bzw. Reparatur: - Tuner: Abgl. 1.3
Abgleich 1.3 Tuner-AGC
Vorbereitung Spektrumanalyser oder HF-Millivoltmeter symmetrisch an Tunerkontakt 10, 11. Senderbild oder Generator über die Antenne einspeisen, 70�80dBµV.
Abgleichvorgang
Mit den Tasten "z -" oder "+ g" 102dBµV (360mVss) einstellen. Ersatzweise wird ohne Spektrumanalyser oder HF-Millivoltmeter mit den Tasten "z -" oder "+ g" das Bild so abgestimmt, da� es gerade zu rauschen beginnt. Dann Dialogzeile "AGC" über " " (DIALOG CENTER) �> "OK" soweit zurückstellen, bis das Bild wieder rauschfrei wird. �> SERVICE �> "OK" �> Service Code "8500" �> aufrufen. Dialogzeile "End" mit "with mem" beenden.
Hinweis:
Es werden in den Chassis CUC 20xx TDA 8843/8375 bzw. TDA 8843-N2/8844-N2 eingebaut. Bei dem Typ TDA 8843-N2/8844-N2 ist ein PLLDemodulator integriert und somit entfällt der AFC-Abgleich im Service Menü. Achtung! Nach einer Reparatur bzw. Wechsel des NVM (IC82005) mu� kontrolliert werden, ob der NTSC Quarz 3,58MHz bestückt ist. Bei nicht bestücktem Quarz, mu� über das Service Menü der Menüpunkt "NTSC 3,6" auf "aus" gestellt werden. �> OK �> SERVICE �> OK �> Service Code "8500" �> NTSC 3,6 "aus" und das Menü mit "with mem" verlassen

Alignment
1. Chassis Board
Measuring instruments: 10:1 test probe, colour video generator, spectrum analyser or RF millivoltmeter. Service works after replacement or repair of the following modules: - Tuner: alignment 1.3
Alignment 1.3 Tuner AGC
Preparations Spectrum analyser or RF millivoltmeter symmetrical to tuner contact 10, 11. Feed in a standard test pattern or generator via the aerial, 70�80dBµV. Call up the dialog line "AGC" via " " (DIALOG CENTER) �> "OK" �> SERVICE �> "OK" �> Service Code "8500".
Alignment Process Adjust 102dBµV (360mVpp) with button "z -" or "+ g". Alternatively, without using a spectrum analyser or RF millivoltmeter, adjust the picture with button "z -" or "+ g" so that noise just appears on the screen. Then reset until the picture is again free of noise. Dialog line "End", terminate "with mem".
Note:
The CUC 20xx chassis is fitted with TDA 8843/8375 or TDA 8843-N2/8844-N2. Type TDA 8843-N2/8844-N2 has an integrated PLL demodulator so that the AFC needs not to be adjusted via the Service Menu. Attention! After repair or replacement of the NVM (IC82005) it is to be checked whether the NTSC 3.58MHz quartz is fitted. If this quartz is not inserted the menu option "NTSC 3.6" in the Service Menu must be set to "off". �> OK �> SERVICE �> OK �> Service Code "8500" �> NTSC 3.6 "off" and leave the menu with "with mem".
