Vertical Deflection Troubleshooting
No Vertical Deflection: The first instinct of the technician is to go after the vertical output IC1501 and understandably
so. It is a drive component with heavy current usage and heat dissipation, and it is usually the cause of the
failure. It is almost a given that F651 and/or F652 on the G board will also open. .
The first check that you should perform (and this applies to all Sony televisions of the last seven years) is to
check the voltage level of the clock and data lines on the I
2
C bus. They are conveniently labeled SCLK and
SDAT. The DC voltage should not be lower than 4.6 volts. If either of these lines is loaded down, the vertical
oscillator will not start. This is the number one cause of multiple component replacement for a simple vertical
problem. You should always check the clock and data level whenever you have a strange problem, particularly
if it appears that multiple symptoms are present. Although most television chassis’ will not produce vertical
deflection, some will generate other symptoms. As an example: The AA-2W used in Sony’s KV32/36XBR200
sets will display a magenta raster with no video and insufficient vertical height that can easily cause a technician
to look for separate failures and blame the y/C Jungle IC. Assuming the bus is okay, move onto the next
scenario:
