All capacitors are in µF unless otherwise noted. pF : µµF 50V or less are 
not indicated except for electrolytics and tantalums.

All electrolytics are in 50V unless otherwise specifi ed.

All resistors are in ohms.  kΩ=1000Ω, MΩ=1000kΩ

Indication of resistance, which does not have one for rating electrical 
power, is as follows:

All variable and adjustable resistors have characteristic curve B, unless 
otherwise noted.

Readings are taken with a color-bar signal input.

Readings are taken with a 10MΩ digital multimeter.

Voltages are DC with respect to ground unless otherwise noted.

Voltage variations may be noted due to normal production tolerances.

All voltages are in V.

 symbol are critical for safety. Replace 

The components identifi ed by X 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 necessary, replace 
only with the value originally used.

When replacing components identifi ed by Y, make the necessary 
adjustments as indicated.  If the results do not meet the specifi ed value, 
change the component identifi ed by X and repeat the adjustment until 
the specifi ed value is achieved. (Refer to Section 3: Safety Related 
Adjustments on Page 16.)

When replacing the parts listed in the table below, it is important to 
perform the related adjustments.
