Helpd me mont a new carradio when prewius mont was a mess.
;
Very good service and quick service, very good quality of service manual!
;
Great tape deck manual!
I'm very positively surprised, because it is a very long manual, lot of pages, drawings, diagrams, description of how to make the alignment and adjustment procedures.
It is as good as the old "Naka" manuals from the 1970's - if somebody have seen them, they know what I mean by that.
I recommend to buy this very much !

I am a vintage hifi collector. No way to fix that device without the appropriate service manual...thanks to your site I got it and every thing is easier now. I got the manual right after ordering: fast cheap accurate ... thank you
;
Wonderful job clear. Qick fantastic. These people are really good. If even a problem arise they are wonderful assisting you. These scheme is so net despite this is a very old TV. Thank you for everything!!!!!!!!
2-2-6. Adjustment for the Power Board When the Panel is Replaced
2-3-2. Notes
(1) Without any special specification, the Module should be at the condition of preliminaries more than 10 minutes before adjusting. . Service signal : 100% Full White signal . Service DC voltage : Vcc : 5 V, Va : 65 V, Vs : 190 V . DC/DC Pack voltage : Vsetup : 220 V, Vscw : 115 V, _Ve : _35 V, _Vy : _75 V . Preliminaries environment : Temp (25 ± 5°C), Relative humidity (65 ± 10%) (2) Module should get the Aging for the equilibrium after finish the assembling. Aging condition is shown below. . Service signal : 100% Full White, Red, Green, Blue pattern signal (Service time of each pattern : within 5 minutes/cycle) . Service DC voltage : Match the voltage with the set up voltage in the first adjustment. . Aging time : More than 4 Hrs . Aging environment : Temp (60 ± 2°C), relative humidity-Less than 75% (3) Module adjustment should be followed by below sequence. . Setting up the initial voltage and adjusting the voltage wave form of Vsetup . Measuring the Margin of Vs voltage and deciding the voltage . Adjusting and checking the voltage of DC/DC pack (Vsetup, Vscw, _Ve, _Vy) . Adjusting the voltage wave form of Vset-down . Measuring the voltage margin of Vset-up and deciding the voltage . Adjusting the wave form of final voltage But, these items above can be changed by the consideration of mass production. (4) Without any special specification, you should adjust the Module in the environment of Temp (25 ± 5°C) and Relative humidity (65 ± 10%) c If you let the still image more than 10 minutes (especially The Digital pattern or Cross Hatch Pattern which has clear gradation), after image can be presented in the black level part of screen.
The label shown in the picture above is stuck on the upper right position at the back side of the panel, on which the Va and Vs voltages for each panel are described.
Vs adjusting VR Va adjusting VR
The Vs and Va adjusting VRs are located at around the center part of the power board as shown in the picture. After replacing the panel, adjust each VR so that it becomes the voltage described in the above label (± 0.5 V). Voltage measurement is performed between pin 1 of CN807 and chassis GND for Vs, and between pin 6 of CN807 and pin 10 of CN806 for Va.
