 : panel designation, adjustment for repair.

 Indication of resistance, which dose not have one for

rating electrical power, is as follows.

 All variable end adjustable resistors have characteristic

curve 

 unless otherwise noted.

 The components identified by 

q 

in this basic schematic

diagram have been carefully factory-selected for each set

in order to satisfy regulations regarding X-ray radiation.

Should replacement be reauired, replace only with the

value originally used.

 When replacing components identified by 

q 

, make the

necessary adjustments indicated. If results do not meet

the specified value, change the component identified by

q 

and repeat the adjustment until the specified value is

 to R381 adjustment on Page 15, 

16.)

When replacing the part in below table, be sure to per-

form the related adjustment.

. Voltages are dc with respect to ground unless otherwise

noted.

 All voltages are in V.

 Reading are taken with a color-bar signal input.

. Reading are taken with a NTSC 358 color-bar signal input

 Voltage variations may be noted due to normal produc-

tion tolerances
