7-2

CKE5507L/LM

7-3 No Raster

Check the horizontal drive

circuits. (IC401)

Does the drive pulse appear

at Pin 26 of IC401?

Yes

Check Q403 and T401

Does the drive pulse

appear at the collctor of

Q403?

Yes

Check its related circuits

(R414 and C411)

WAVEFORMS

Check flyback pulse at the

collector of Q402 connection of

CN502 and its related circuits

(D403, D409 and T501)

Does the drive output

pulse appear at the base

of Q402?

Yes

106.4 V (Q403, Collector)

CH1 P-P = 106.4 V CH1 RMS = 44.92 V

8.48 V (Q402, Base)

CH1 P-P = 8.48 V

CH1 RMS = 1.252 V

3.80 V (IC401, #26)

CH1 P-P = 3.80 V

CH1 RMS = 2.376 V

1.080 kV (Q402, Collector)

CH1 P-P = 1.080 kV CH1 RMS = 208.0 V
