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 jest OK. Schematy czytelne, opisane niektóre procedury.

(3) R ch 1) Connect Oscilloscope to TP5201 <R>. 2) Add 2.25 ± 0.02 V to TP5211 <RLBS> 3.95 ± 0.02 V to TP5210 <RHBS> by DC power supply. 3) Confirm that the signal level under 10 IRE and above 80 IRE is increased with above condition.
60 mV
4) Turn RV5401 <GL, GAIN> to the right direction and adjust so that �0 IRE ~ 10 IRE� might be 180 ± 10 mV.
10 IRE 180 mV 0 IRE
5) Change TP5411 <GLBS>, TP5410 <GHBS> to OPEN. 6) Turn RV5402 <GL, BIAS> to the left direction and adjust so that �10 IRE ~ 40 IRE� might be 380 ± 10 mV.
40 mV 60 mV
40 IRE G ch 380 mV 10 IRE
4) Adjust RV5201 <RL, GAIN> so that signal level of �0 IRE ~ 10 IRE� might be 130 ± 10 mV.
10 IRE 0 IRE R ch 130 mV
(5) B ch 1) Connect Oscilloscope to TP5601 <B> 2) Add 2.20 ± 0.02 V to TP5611 <BLBS> 3.95 ± 0.02 V to TP5610 <BHBS> by DC power supply. 3) Confirm that the signal level under 10 IRE and above 80 IRE is increased with above condition
60 mV
5) Turn RV5209 <RH GAIN> to the left direction by aplox 150° and adjust so that �90 IRE ~ 100 IRE� might be minimum.
40 mV minimum 60 mV
(In Case that �100 IRE ~ GND� is above 3.7 V ; Adjustment is N.G) (4) G ch 1) Connect Oscilloscope to TP5401 <G>. 2) Add 2.25 ± 0.02 V to TP5411 <GLBS> 3.95 ± 0.02 V to TP5410 <GHBS> by DC power supply. 3) Confirm that the signal level under 10 IRE and above 90 IRE is increased with above condition.
2.0 ± 0.02 Vp-p
4) Turn RV5601 <BL, GAIN> to the right direction and adjust so that �0 IRE ~ 10 IRE�might be �160 ± 10 mV�
65 mV 90 IRE
