I got a tip on here about blowing out or cleaning the cooling fan, but can't seem to find it. Am I missing it, or does this model not have one? P.S. it has no picture, and LED blinks 4 times then stops and blinks 4 times.

Re: can't find the cooling fan
Unfortunately, you apparently got information from someone who has not had training on your set. A 4 flash on your set indicates a vertical stop, meaning that the vertical drive circuit has shutdown. Possible causes are a bad vertical drive or vertical output IC. I can't be more specific because I would have to check a couple of things, starting with the 135 volt power supply line to see if it is coming up. You can stop looking for a cooling fan because this set does not have one.

You said you "cleaned" the fans. Have you tried removing the large fan -- on the left side when you are standing in the back of the TV -- and actually pulling out the fan itself? One side of the fan casing has a sticker -- with the model number written on it -- and the other side is the fan itself. Carefully pull the fan out -- it's held by magnets, no screws -- then clean the spindle thoroughly with a Q-tip dipped in rubbing alcohol. Also, clean the opening on the casing itself -- the hole is too small for a Q-tip, so use a toothpick, again dipped in rubbing alcohol.
For additional cleaning, use compressed air to blow the hole. After the alcohol dries, use another Q-tip and spray a little WD40 on one of the tips. Sparingly apply the WD40 to the fan spindle. Place the fan back into the casing, screw the cover back on and try the TV again.
This is probably a heat issue (assuming you aren't the one turning off the TV and aren't having regular power failures). This TV has two fans to help keep the components cool; if the temperature increases, the TV will shut down to protect those components. Also check if the ventilation slots are blocked and clean the dust off them. (When you have the TV open, you can blow out dust as well - much like dust removal for a desktop CPU.)
ok.. my first instinct for this problem is airflow... check to see if the filter is cloged or blocked...make sure the fan is blowing to cool it. if this all seems right then you might have what is called a faulty ballast. which may need replaced. or the fan might be jammeded.
Yes the fan activates when the TV gets a certain level of temp now if this never comes on it would need to be replaced with a new fan motor. I would keep a eye on it if you TV seems to be too darn hot because this can cause falures if it does not cool off the unit.. Thanks and please rate.
