Glad you made progress. If you are doing the PIN problem
next watch the diodes around the Hoz output. Also electrolytics
in the PIN circuit. Its best to use OEM semi's if you can find them.
Adjustments are often done through an OSD service menu. If you
change anything there ALWAYS write down the old number so you
can go back if needed. Also when you exit the menu it wont
save the settings if you dont follow the manual.
