Sony flat screen four blink code question
 
This is my son's set. It was given to him about six months ago by
someone who didn't know what the four links most likely meant. I
removed the fan, disassembled it, cleaned the shaft and bushing with
isopropyl and relubricated it with a small amount of ATF,
(transmission oil). It has been fine until recently when it started
sporadically shutting down again with a four blink code. So I'm going
to investigate it again. I know that I can purchase a new fan, however
I just thought that maybe a different lubricant, one that doesn't get
sticky when subjected to high temperature is what I need. Has anyone
done this successfully? Thanks, Lenny

Realize that the blink code only indicates an airflow problems that may or may not be the fan itself. Clean the entire area including the air "tunnels". There are flow sensors around that can trip this error as well. Basically, clean the entire area with a vacuum or compresed air. Also, this error condition can occur if the cover switch is not completely compressed. Verify that the access door is completely closed and secure.

Thanks for the tip Dan. We're going to look at it tonight. Lenny

Oils for automatic transmissions are tolerant of heat, but an accumulation
of fine dust will wick oils out of bearings.
As long as the ATF isn't smoking, it's still lubricating and isn't going to
turn waxy or thick from a little warmth.
