42" Panasonic plasma TV model: TH-42PX60U, year: Nov 2006, no power,
no blinking or standby LED lights. The TV was on while this happened.
Upon troubleshooting I discovered F401=8 amp ceramic time lag fuse to
be open. From extensive googling after no obvious shorts in power
supply using Fluke DMM model 29 series II. I found the following
common repair tips:

Q406=N-ch MOSFET # RJK5020=Panasonic # B1DEKQ000003=shorted
R410=10 ohm, 5w ceramic thermal cut off=Panasonic # D1F5100E0003=open
F401 & F402=8 amp ceramic time lag fuse= Panasonic # K5D802BNA005= one
or the other open

well on this TV none of the above parts are defective except F401.
According to a Panasonic service bulletin for a similar model:

http://www.tvrepairtips.org/files/tip/286/tt-08-27.pdf

they say to add a C426=ECQB1H103JZ but on that bulletin it's if Q406
is shorted but not on mine and the board on the service bulletin is
somewhat different than mine. I haven't yet replaced F401 or placed a
100 watt light bulb in place. But would like some tips before I
proceed. Thanks.
