Sony KP-46WT520 Service Manual page 63

Circled numbers are waveform references.
The components identifi ed by X in this basic schematic diagram have been
carefully factory-selected for each set in order to satisfy regulations regarding
X-ray radiation. Should replacement be necessary, replace only with the value
originally used.
When replacing components identifi ed by Y, make the necessary adjustments
as indicated. If the results do not meet the specifi ed value, change the
component identifi ed by X and repeat the adjustment until the specifi ed value is
achieved.
(Refer to adjustments in Sections 3-1 and 3-2.)
When replacing the parts listed in the table below, it is important to perform the
related adjustments.
