The following information is excerpted from the Service Manual.
To get to the Service Menu:
Set to "0 minutes" using the [SLEEP TIMER] key.
While "0 minutes" is displayed, press the [VIDEO STATUS] key and [DISPLAY] key simultaneously, then enter the SERVICE MODE (Fig.1)
Before entering the SERVICE MODE, confirm that the setting of TV/CATV switch of the REMOTE CONTROL UNIT is at the "TV" side and the setting of VCR/DVD switch is at the "VCR" side. If the switches have not been properly set, you cannot enter the SERVICE MODE.
To see the input signal:
press 1. ADJUST
The following screen appears (see attachment).
The signal displayed on the screen is displayed.
NTSC3 : 525i (Composite / S-video input)
525I : 525i (Component input)
525P : 525p
1125I6 : 1125i
750P6 : 750p
PCVGA : PC (VGA)
PCXGA : PC (XGA)
PCNG : PC (except VGA/XGA)
H525I : HDMI 525i
H525P : HDMI 525p
H125I6 : HDMI 1125i
H125P6 : HDMI 1125p

I couldn't find in the Service Manual where it states the lower left-number on the Self Check screen was the lamp hours. That's what I remember, though.
