Could have been all 3 flashing as I have a colour blindness problem & am having a hard time seeing these. Got better lighting to see it.
Left it unplugged overnight. Upon plugging it in this AM this is what it does;
Standby//temp light comes on for 2 seconds then goes off.
Then Lamp light flashes by itself for abt 20 secs. Goes off
Standby/temp comes on for 2 secs, then goes off
Lamp light then flashes for abt 20 secs., goes off
Standby/temp light comes on for 2 secs, then goes off
Lamp light comes on for 20 Secs., goes off
Then all 3 lights (timer, Standby/temp & lamp) come on flashing
& continue flashing (forever)?
My daughter (her TV) says all three lights flashed when it started shutting down (before we replaced the lamp & ballast)
