Final Check - Sony KP-57XBR10W Service Bulletin

TV Products Service Bulletin No. 531
Apply a 1080i signal to the Video 5 input and go into service mode. Turn on internal
crosshatch signal and adjust as needed. Please note, a 1080i signal MUST BE APPLIED to
the Video 5 input for the internal crosshatch generator to enter the 1080i mode. If this is not
done, the pattern displayed will not be 1080i but stay in the NTSC 480i mode. Please note:
If a 1080i crosshatch generator is available, use this signal to adjust rather than using the
internal pattern (this is a preferable method). If the mode checks OK, continue to the next
step, if not, adjust the set in the Fine Mode. After any new data is written (by pressing
"MUTING: then "ENTER"), press "Flash Focus" in service mode so that TV can calculate
the new offset data.

Final Check:

Now check each mode with a live video signal to verify correct operation. If problems
still exist, please readjust. If a 1080i source is available, please check this mode.
Final steps, please enter the menu and select the Video Icon and view the set in Standard
Picture Mode and then in the Vivid Picture mode. When Vivid is selected, please lower the
brightness level slightly (10%). Blacks should appear black, not gray. Please select the
mode that looks best to the dealer. Please Circle the Mode you selected to leave the set in:
Standard / Vivid ). Also, confirm that the Dynamic Picture Function is ON (in the Video
Icon Menu).
