Hello my name is Eric,
Welcome to Just Answer
I can help you with this issue,
Four blinks is usually the error code for a bad fan, usually its the big one in the rear vent, but could be an other one.
Try spinning the fan with a straw (poke it through the vent)

You can use a flashlight to see if both fans spin upon turn on.
Here is a photo of the rear fans with two arrows pointing at the fan vents
The fans are not that hard to replace , just a philps screw driver is needed
The middle (rt side) fan is (#57) Main Chassis Fan 1-787-333-11 D.C. FAN
Left side (#51) Main Exhaust Fan 8-835-860-11 MOTOR, DC SFF21C/C-NP
I'll bet one on them does not even spin, its stuck or won't spin freely.
its the fan on the same side of the lamp that is not working.I was able to take the cover off the tv..but i see a bunch of cables..now are these cables all for the fan or is there just one....also do you have a part number for that fan
There is just one connector for the fan, just make sure you do not remove the fan and then forget the direction it is in. There are two screws holding it in. move the little blue things to the new fan , making sure the fan faces the same direction and where the wire goes through also.
to buy a fan click here login as a guest and search for part# XXXXXBest of luck
I was able to remove the fan...thank you for all your help
Mark the direction it is in so you have the new one blowing air in the correct direction.
Best of luck
