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.
Instrukcja bardzo czytelna. zawiera co potrzeba. Polecam

4 Connect the GND probe of DMV to the GND of the Y B/D, and connect the positive probe to the lower leg of R44 to check the _Vy voltage (_175 ± 1 V). When there is abnormality in the voltage, turn the variable resistor (PS2) of DC/DC Pack (_Vy) on Y B/D to adjust it. 5 Connect the GND probe of DVM to the GND of the Z B/D, and connect the positive probe to the upper leg of B34 to check the Vzb voltage (_105 ± 1 V). When there is abnormality in the voltage turn the variable resistor (A2) of DC/DC Pack (_Vzb) on Z B/D to adjust it. 3) Measuring the Vs voltage margin and determining the voltage 1 Switch the signal of the signal generator to the 100% Full Red signal. 2 Turn the voltage adjusting knob of the Vs DC power supply in the voltage-down direction, and turn off the cells of the screen. 3 Turn the voltage adjusting knob of the Vs DC power supply in the voltage-up direction until the cells of the screen turn on. The first voltage, which turns on the cells of the entire screen, is named as Vsmin1. Record the value of Vsmin. 4 Turn the voltage adjusting knob of the Vs DC power supply in the voltage-up direction slowly until the cells of the screen turn off or until overelectric discharge happens. The first voltage, which turns off the cells of the screen or causes over-electric discharge, is named as Vsmax1. Record the value of Vsmax1. (Note that the Vs voltage variable should exceed the maximum of 195 V.) 5 Switch the signal of the signal generator to the 100% Full Green signal. 6 Repeat the previous adjustment step (2), and record each voltage as Vsmin2/Vsmax2. 7 Switch the signal of the signal generator to 100% Full Blue signal. 8 Repeat the previous adjustment step (2), and record each voltage as Vsmin3/Vsmax3. 9 Switch the signal of the signal generator to 100% Full White signal. 0 Repeat the previous adjustment step (2), and record each voltage as Vsmin4/Vsmax4. !- Switch the signal of the signal generator to 100% Full Black signal. != Repeat the previous adjustment step (2), and
record each voltage as Vsmin5/Vsmax5. ![ At this time, the maximum voltage is set by adding 6 V to the Vs voltage (Vsmin1 to Vsmin5). Set the voltage within the setting range (180 V < Vs < 195 V) while considering other characteristics as well. !] Turn the voltage adjusting knob of the Vs DC power supply, and determine the Vs voltage. !\ Adjust the Vset-down waveform by setting the Vs voltage as described in 2-3-4. 4) Adjusting the final voltage waveform 1 Check the voltage waveform as described in 2-3-4 (3. How to adjust), and readjust the waveform when it is out of range. 5) DC-DC Pack voltage setup range V1st : 100V to 160 V Vsc : 100 V to 160 V _Vy : _160 V to _200 V _Vzb : 100 V to 160 V
