I owned 2 Panasonic TV 1 is 37" LCD and a 42" Plasma is that Flushing Light comes from the Power ON or is it the Green LED light for Tuning?Pls.be specific what size of LCD do you have?Model or Year you bought it?
Anyway try to contact your nearest Panasonic Service Ctr in
your area...but I think it's the POWER of your TV that must be Repaired ...
There is NO Fan inside of any Panasonic LCD TV neither in Plasma ...
