It has all the information you will need to fix it. The main circuit diagram is only A4 but being a PDF, you can print it to any size - I did it on two sheets of A3 and it didnt lose any detail - just made it readable when pinned up above the bench. I've found the fault, just need to buy some obscure bits to get it going again!
I cant fault the process, I paid for the manual in the morning and it was ready to download by lunch time.

Very good copy in a 54 pages PDF archive. This is my sixth purchase here. :)

Another excellent buy! File too clear and explanatory.

A manual hard to find. It was very helpful to restore my device.

I am very grateful for this manual. Without it could not repair my receiver.

Der folgende Abgleich Nr.2 für die Schirmgitterspannung ersetzt entsprechenden Abgleich im Service-Manual 720100261000, Seite 3-1. Abgleich 2. Schirmgitterspannung UG2 Vorbereitung Graubalken-Testbild einspeisen. Bildschirmhelligkeit so einstellen, dass die Abstufung vom dunkelsten Graubalken zu schwarz gerade noch sichtbar ist, ca. 2,7V an IC150-(17). Kontrast: Minimum An den Messpunkten R, G, B (auf der Bildrohrplatte) Oszilloskop anschlie�en und den höchsten Schwarzwertpegel ermitteln. Abgleichvorgang Mit Regler UG2 (Splittrafo) an dem Messpunkt mit dem höchsten Schwarzwert eine Spannung von 110V�115V für14"-Bildröhren und von 145V�155V für 15"�21"-Bildröhren einstellen.

The following adjustment No. 2 for the Screen grid voltage substitutes the adequate adjustment in the Service Manual 720100261000, page 3-2. Adjustment 2. Screen grid voltage UG2 Preparation Feed in a grey scale test pattern. Adjust the screen brightness so that the gradation from the darkest grey scale value to black is just still visible (2.7V to IC150-(17)). Contrast: Minimum Measure test points R, G, B (on the CRT panel) to determine the test point with the highest black level and connect this point to the oscilloscope. Adjustment Procedure With the control UG2 (Splitt Transformer) adjust the black level at the test point with the highest black level to 110V�115V for14" picture tubes and 145V�155V for 15"�21" picture tubes.
