Fujitsu airon ASTA24LCC 2 flashes green and red then 5 red flashes any idea what it means


Had similar problem (ie. 2 green & red flashed followed by 5 red flashes - Fan blowing but not cooling ... I also noted that the outside unit fan wasn't going). Tried restarting several time after waiting only a minute or two after turning the mains power off but with no change. So turned the unit off at the mains power and then fired it up about 2hrs later and it was all working fine.

you need to change your power box there is a bad connection with the wires. its over heating you might whant to buy another at game stop or take it in to get fixed. the more you messed with it it might mess up your whole system.

TV turns itself off, then on automaticlly


The fan should run for a few minutes after shut off to cool the lamp down.

If I read and understand correctly somewhere in the cycle you are getting 5 red blinks? that is an error code........

Either you or I can Google the model number of the set with 5 blinks.....or visit the Sony site to see what it means.....

Powering on


OK ... after a lot of trial and error, I got mine to work. I think it may be a really low charge or something. I had to press the power button until it was completely dark ... no flashing faint green or any colors. Then when I plugged it in, I got a solid red and left it for awhile. Then when I pressed the power button I got yellow, red and green ... the computer recognized it and then got a solid yellow.

Before when I had it plugged in, I'd get a lot of red random flashing ... and it just didn't seem to charge at all ... even after a full day.

I think the issue was that it was in this "flashing state (red when connected, very faint green when disconnected)" It wasn't easy to get it to turn off completely. Most of the presses of the power button didn't change the state at all. But if I got it just right, I could see the faint green light go off. That's when I plugged it in and got a solid red light, and eventually a good charge.

Hope this works for some others.
