Awesome manual. Complete diagrams of all board assemblies as well as how to get to each part of the t.v. down to the individual screws and their locations. Get it.
This is exactly the service manual I needed.
Complete with all schematics, partslists, PCB layouts and alignment instructions.
This manual covers both the T-4970 en T-488F Onkyo tuner.
IF PRINTED CIRQUIT BOARD WIRING VIEW WAS ONE TONE LIGHTER, THEN 5 STAR RANK HAS TO BE MY CHOISE.
