Question about Panasonic PT-50DL54 50" Rear Projection HDTV-Ready Television
When I turn on my Panasonic PT-50DL54 TV, The power LED flashes green several times, then flashes red three times, pauses then flashes red three times. This sequences of three red flashes repeats over and over. The TV never does come on. I bought a shop manual that says there is a problem in the Fan SOS circuit. Any idea on how to narrow it down further.
Problem is fan stoppage this is probable caused by excessive
dust in fan take off back and locate visually the cooling fans in unit
use canned air to remove dust until fan moves freely. if all fans
are clean maybe one fan is not giving rotation detect signal
look at voltage on white or yellow wire from fan s/b 5v then 0v
when fan rotates if one stays at 5v replace it
