5 Troubleshooting

5-1 Parts Level Troubleshooting

Notes:

1. If a picture does not appear, Click the Brightness and Contrast button on the front panel, and then increase the value

of Brightness and Contrast.

2. Check the following circuits.

• No raster appears: Power circuit, Horizontal output circuit, H/V control circuit, and H/V output circuit.
• High voltage develops but no raster appears: Video output circuits.
• High voltage does not develop: Horizontal output circuits.

5-1-1 No Power Supply

Check and replace FG601, D601,

D701, Q701, IC601 and ZD601.

Done.

IC601 Pin 1 waveform is right?

Check and replace

IC601, ZD601, D606, IC701.

Check and Micom. (IC201)

•

Check and replace IC651.

•

Check every IC connected to 12V.

Yes

Check the Voltage at

C607 plus polarity point.

Is the Voltage 400V

with PFC : 400V

without PFC : it is different

according to input voltage

Check and replace

FG601, D601, D703.

Yes

The secondary voltage of

T601 is right?

(Is it same the schemetic diagram)

Check TR, IC and biode

related to every B

line.

Yes

•

Check IC651 (KA78R12) Pin 12?

•

Is the voltage 12V

Appear 4V

Pin 4 of IC651?

Yes

CONFIDENTIAL

WAVEFORMS
