CONFIRMATION

• All voltages are in Volts

•Voltage is DC with respect to ground unless otherwise noted.

•

Readings are taken with a 10MΩ digital multimeter.

• Readings are taken with a color-bar signal input.

•

Voltage variations may be noted due to normal

 

production tolerance.

•Circled numbers are waveform references.

•* : cannot be measured

•: B + Line

•----- : B − Line

• : Signal path

A BOARD: IC502 STV9379 (KV-32FS12/32FS16 ONLY)

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

•The components identified by in this manual have been carefully factory-selected for each set in order to satisfy regulations regarding X-ray radiation. Should replacement be required, replace only with the value originally used.

•When replacing components identified by , make the necessary adjustments indicated. If results do not meet the specified value, change the component identified by and repeat the adjustment until the specified value is achieved (refer to Safety Related Adjustments on page 20).

•When replacing parts shown in the table below, be sure to perform the related adjustments.

Note:

: ALR

HIGH RIPPLE

 

 

The components identified by shading and mark are critical for safety. Replace only with the part number specified.

The symbol (displayed on component side of the circuit board) indicates fast operating fuse. Replace only with fuse of the same rating as marked.

Les composants identifiés per un tramé et une

marque sont critiques pour la sécurité. Ne les remplacer que par une piéce portant le numéro

spécifié. Le symbole indique une fusible a action rapide. Doit etre remplacee par une fusible de meme yaleur, comme marque.
