RV901

HV ADJ

When replacing or repairing the shown below table, the

following operational checks must be performed as a

safety precaution against X-rays emissions from the unit.

 Beam Current Protector Circuite Check

(1) Hardware logic circuit

Turn the POWER SW on, and check that the RASTER

fades in.

Connect a variable resistor (20 k

 or more) and an

ammeter in series between FBT pin 

!]

 and – 15 V line

(– side of C637). Decrease gradually the resistance of

the variable resistor from maximum to minimum, and

confirm that the Beam Current Protector Circuite

works (TV Rester disappears). The current must be

within the range shown below.

Standard current: Less than 1.09 mA

(2) Software logic circuit

Turn the POWER SW on, and check that the RASTER

fades in.

Short b of C639 and GND.

Connect a variable resistor (20 k

 or more) and an

ammeter in series between FBT pin 

!]

 and – 15 V line

(– side of C637). Decrease gradually the resistance of

the variable resistor form maximum to minimum, and

confirm that the Beam Current Protector Circuite

works (TV Raster disappears). The current must be

within the range shown below.

Standard current: Less than 1.14 mA

Confirm one minute later turning on the power.

 HV Protector Circuit Check

(1) Confirm that the voltage between cathode of D913

and GND is more than 17.5 V DC.

(2) Using external DC Power Supply, apply the voltage

shown below between cathode of D913 and GND,

and confirm that the HV HOLD DOWN circuite

works. (TV Rester disappears)

Standard voltage: Less than 23.40 V DC
