Display Screen Proximity?

Hi.

I have had thesame problem, butcontinuously.

The errorwas the same 4SNS/1/40000000: TLOP -130.000.

In the end,after muchlooking,it was abad cable connectionoftemperature sensorof the LCD. iMac 24" early 2008.

I havechangedthe cable andproblem solved.

AlthoughI respondvery late,I hope it canserveto youor othersto look for thesame problem.

Ciao.

which cable did you replace I have been having problems with my monitor, you can read my previous posts. It would be great if it was just a simple cable and not the monitor that needed replacing. Hense the question which cable?

Thanks

The monitor, at the top, has a temperature sensor. The cable is black. In my case, the sensor cable was not good contact, so I gave the error. I just managed contact and everything returned to normal operation.

I also took the iMac to an Apple specialist and was told they had to change the whole logic board, not the sensor.

They just want to make money, in my opinion do not care about the consumer, because in my case, I asked 700 euros, when I got to repair that cost me nothing, just my work.

In your case, check your cable makes good connection.

If not this cable, tests the other cables of the temperature sensors or the same sensors. On the Internet you can find schedules of all temperature sensors in your computer. On the Internet you can also buy the cables and sensors.

You only need to test what sensor or cable is failing you.

If you're not very good with these things, find a friend to help you. As a last resort, if you do not detect which sensor is failing you, you can change all the cables and all temperature sensors before replacingthe motherboard.

Sorry for my bad English.

If I can help you more, tell me.

luck

Thanks for the reply and you English is fine, my wife is Colombian and speaks the same way, lol

I checked the connection on the sensor and it is good. The top of the monitor does get very hot but I don't know how hot is to hot so it doesn't help any.

It is really strange my computer works fine using the Mac monitor without any issues as long as I have an external monitor installed. If the external moniter is unpludgger the computer will start normally, allow me to sign in, show my desktop screen and and the exact same look that is had when it froze on me over a month ago. Then the computer freezes and the mouse pointer is hard to control and will not allow me to open or close anything and the dock station will not pop up. When I start the computer normally without a external monitor the file system gets corrupted every time and if I reboot holding th "C" with the OSX disk it will not boot to the OSX. After ten minutes the screen goes to white most of the time, black a few times and for the first time, just a minute ago it turned red.

If I reboot with the external monitor installed it functions normally and works great. I can also boot to the OSX with "C" key and fix the corrupted file system. That makes no sence. If it was a monitor overheating issue how would an external monitor change that?

I have learned that tech support does not have the equipment to properly test hardware parts they just replace struff. I also understand that it is a time issue and the hourly rate to do a thorough test to find what is really wrong is not cost effective. I have spent atleast 6 hours already. With what I have learned I could do it now in 2 hours to get to the same place. If the fix ends up to be simple and cheap then it would be cost effective. If it ends up to be the monitor then I saved nothing and wasted a lot of time and energy, but I did have fun. I only wish I had the equipment and experience (or book) to properly test each part.

Any advice or thoughts as to what the problem could be?

Hello, from what I understand from your last post, you not only havethe fan problem, the Mac monitor only works when you haveanother monitor connected externally.

OK, I can not help you because I have no experience and I'm not technical. I can only say that my Mac monitor also becomes very hotwhen working normally.

As you mention, the monitor of your mac works, it is not broken and the video signal arrives perfectly (if only when you have an external monitor connected, but arrives).

The authorized Apple repair shops do not think they give you the solution. I would try at a diferent computer retailer to find the right person who really know the problem and give you an easy and economical solution.

Sorry I can not help yourself more.

good luck
