Dokładna dokumentacja, pomogła w szybkiej naprawie telewizora. Dziękuję!
 ;
jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.
;
Wszystko w porządku.
Instrukcja czytelna i kompletna.
Dziękuję.
all right!
thank you.

Instrukcja jest OK. Schematy czytelne, opisane niektóre procedury.
11. D/D Drive & Convert Circuit. This circuit is used for supplying B + voltage to horizontal deflection output transistor (Q708). This circuit makes to add side-pincushion correcting signal to B+ voltage. 12. Horizontal Deflection Output Circuit. This circuit makes the horizontal deflection by supplying the saw-tooth current to the horizontal deflection yoke. 13. High Voltage Output & FBT (Flyback Transformer). The high voltage output circuit is used for generating pulse wave to the primary coil of the FBT (Flyback Transformer (T701)). A boosted voltage (about 26kV) appears at the secondary of the FBT and it is supplied to the anode of the CDT. And there are another output voltages such as the dynamic focus voltage. 14. H-Linearity Correction Circuit. This circuit corrects the horizontal linearity for each horizontal sync frequency. 15. Vertical Output Circuit. This circuit takes the vertical wave from the TDA9113 (IC701) and performs the vertical deflection by supplying the saw-tooth wave current from the TDA8172 (IC601) to the vertical deflection yoke. 17. Dynamic Focus Output Circuit. This circuit takes H and V parabola wave from the TDA9113 (IC701), and amplifies these waves to offer to the FBT (T701). 18. H & V Blanking and Brightness Control. This circuit eliminates the retrace line by supplying a negative pulse to the G1 of the CDT. The brightness control circuit is used to control of the screen brightness by changing the DC level of G1.
19. Image Rotation (Tilt) Circuit. This circuit corrects the tilt of the screen by supplying the image rotation signal to the tilt coil which is attached to the CDT near the deflection. 20. Static Convergence Control Circuit. This circuit corrects the convergence of the screen by supplying the convergence signal to the 4H (STC) coil which is attached to the CDT near the deflection. 21. Moire Reduction Circuit This circuit reduce interference between the periodical display pattern and the CDT's slot (or dot). The positions of every other one dot video signal beams (red, green, and blue beam) are shifted finely, thus reducing interference. 22. OSD Circuit. This circuit is used for performing the OSD (OnScreen- Display) function. When a user selects the OSD Select/Adjustment control, the adjustment status displays on the screen. 23. Video Pre-Amp Circuit. This circuit amplifies the analog video signal from 00.7V to 0-4V. This circuit is operated by taking the clamp, R, G, B drives, and contrast signals from the Micom (IC401). 24. Video Output Amp Circuit. This circuit amplifies the video signal which comes from the video pre-amp circuit and amplified video signal is applied to the CDT cathode.
