Follow the power cord inside the set---be aware precautions and care need to be taken when opening the set--easy to damage screen etc if not done properly.
In this set usually not a fuse if dead unless no power light--nothing at all.....
Testimonial: "thanks so much !! there is no power light, nothing ! I took the thermal fuse assembly off the projection housing and forgot that I hadnt put it back before I plugged the set up so it touch the lamp housing and the tv shut off so I am guessing it is a fuse but I can see the fuse but its behind all kind of cirvuit board and I see no way to get it out ?"

I feel bad for you having such problems with the vendor and the technician too.
The location of that filter could be a small window in the back cover itself. could be a plastic window to the left side of the unit and is only a piece of plastic poliuretane kind of black sponge about 5 by 3 inches size .
What im interested telling you about the shut down condition and is maybe even most important than where is the air filter (who is one of the more than ten posibilities why the tv goes to shut down.
Note:
if the air filter is totally obstructed i would give one of ten probabities of suspicious why the tv shuts down:
first because the tv's air duct is not really isolated. The fan can eat air by any side of the air filter base as i said if the filter is totally obstructing which is really extreme. besides maybe the other 2 fans could help to cool down the unit in that case scenario. In my experience Most time the air filter holds tons of dust but is not totally obstructing the air passing, and really some other problems are in the set.
This is the really critical to know: if any of those fans stopped or maybe any sensor is overheated or the lamp is coming to dead or who knows.. a diagnosis is needed for this symptom really common in DLP technology.

Hi,
3 times LED blinks in Panasonic PT-47WX42 shows problem with convergence out chips failure as this tv has two big black ICs STK392-110 as convergence output, replace them to fix tv problem.
Click Part Store to see an image of required chip and price info.
Local tv tech is recommended if you have no experience of working in tv circuit boards.
Thanks.
