5. ELECTRICAL ADJUSTMENT

Notes:
• Before the adjustment:

Electrical adjustments discussed here are often required after replacement of electronic components and mechanical
parts such as video heads.
Check that the mechanism and all electric components are in good working condition prior to the adjustments,otherwise
adjustments can not be completed.

• Instruments required:

• Color TV monitor

• Dual-trace oscilloscope

• Audio signal generator

• AC milli-voltmeter

• Blank video cassette tape

• Alignment tape (VROEFZCS)

• Screwdriver for adjustment

• Color bar generator

• RF signal generator
