Hi. Having recently bought a 2nd hand Panasonic AE300, and gone through this forum looking for information about it, I haven't found anything describing what the various options in the hidden 'service screen' menu do, apart from the 'Flicker' option. FREEZE MSG OFF/ON PIC SHIFT OFF/ON RUNTIME PRT OFF/ON FAN FULLMODE OFF/ON AUTO SETUP NORMAL/SPECIAL SERVICE CHECK SERVICE MODE FLICKER ADJ Some I've sussed, but other's I'm not brave enough to try for fear of breaking something. Anyone been through them all and worked out what they do? Also (just out of interest), on the SERVICE CHECK screen, there are various lamp hour readings - anyone worked out their meanings? On mine they are: Total 232H Reset 0 231H50 135 205H50 0H00 0 0H00 0H00 0 0H00 The Total (232H) is what also appears on the standard Options screen. Reset will be the number of times the counter has been reset when you change the lamp. The rest, I'm not sure - perhaps something to work out the total based on number of hours in low and high, and is used for the 1800hr and 2000hr limits? Cheers, Niall.
