Error in Diagnostics 4SNS/C0000008: TLOp--124

Hi

I have the above error in diagnostics. It appears to point to LCD Temperature Sensor. I have tested another LCD with my Mac and it isn't the LCD itself. This results in fans running at full speed as well as LCD Proximity reading as - in istat menu app.

Any help would be appreciated

Thank you

Soluzione Prescelta

The error TLOp points to: ''Excessive LCD panel area temperature, Verify that the DisplayPort cable is securely connected to both the LCD panel and the logic board. This is straight out of the Apple manual.

I would say since you tried a second display and it too showed the error that points to the LVDS connector on the logic board its self the contact within it has a problem, the solder joint of the connector or the rest of the sensor logic within the logic board needs to be investigated.

I would first check that the the LCD thermal sensor cable connector is correctly in place. See step #8 of this guide:

The thermal sensor cable and connector looks fine. I've examined the pins inside the connector too and they look fine.

I do suspect the lvds connector now that Dan has mentioned it. There's a pin that looks slightly out but because it was working I didn't suspect it. But the more closely I examine it the more I think it is the LVDS connector on the logic board.
