I have a JVC AV-32P903 32" HDTV. I can get into the service menu, however I have absolutely no idea what the values mean. After pressing VIDEO STATUS & DISPLAY at sleep timer 0 min I get the following on my SERVICE MENU: 1. PICTURE/SOUND 2. YC SEP 3. LOW LIGHT 4. HIGH LIGHT 5. RF AFC 6. PIP 7. IC2 BUS 8. PP 9. IP 0. SELF-CHK Since I have a geometry issue I proceed into '1. PICTURE/SOUND'. After entering, I see the follwing values: A01, A02, A03 .... up to A16 S01, S02, S03 .... up to S60 D01, D02, D03 .... up to D20 F01, F02, F03 .... up to F65 Which values with adjust tilt, pin cushion, and pin balance?
