This manual is very helpful, correct shematic diagram, and good exploded view.Perfect!

Alte gescannte Servicepläne sind oft doch etwas undeutlich . Stromlaufpläne werden auf mehrere DIN A4 Seiten aufgeteilt. Alles ziemlich umständlich und zeitaufwendig. Aber mit etwas Mühe geht alles.

Great item, high resolution, detailed, very easy to work with.
;
fast delevery of the manual and very complete manual, now my Akai works again, will buy again, thanks.

Adjust the VP (vertical) and the HP (horizontal) position using the 4, buttons. Press the Memory Initialize key of the R/C to store the value in memory. If you do not have this key, short the pins of the 2 pin connector PI1 for one second, then remove. Select PIP mode and shift the sub-picture using the SHIFT button. Distance between PIP and edge of screen should be equal when shifted. if it is not, repeat (i)-(5). Surround Operation Check Adjustment Preparation Input the following audio signals to the audio input of the VIDEO INPUT terminals. When checking surround: L CH: 400Hz sine wave 475mVrms R CH: 5kHz sine wave 475mVrms Set the INT. SPEAKER : ON Set the volume controls of FRONT and REAR to center. Set the BASS, TREBLE and BALANCE to center. Note: Front waveform: Front speaker output of the set. Rear waveform: Rear speaker output of the set. Surround Off Check Set to SURROUND: OFF and check shown below is obtained.
