LCD Temp Sensor broken on Logic board

Hi

My LCD temp sensor on the logic board snapped off. The pads on the board are not intact so will not allow the wires to be soldered. Ive heard there is a way to override the temp sensor by running the temp sensor wire to some other place on logic board (could be a load of BS) but I thought I'd check with the experts here to see if anyone has had this issue and resolved.

Obviously I can replace the logic board but I want to try and fix this if I can as it's another project machine.

Thanks

@faisalgondal any chance you can post a better picture? This one is to blurry and difficult to check.

Yes it can be done but we need to see a better picture to mark the jumper way for you.

Thanks @oldturkey03

I'm guessing I take the connector side off the LCD temp sensor cable and solder onto the points shown?

@faisalgondal yes you could give that a try.

Thanks. I have 2 wires coming out of the LCD temp sensor, black and grey. The Black would go to the blue line according to your diagram, and grey to the green line. What do I connect to ground? Thanks

@faisalgondal - You also lost the inductor L5521 as well. I would recommend you leave the connectors active. Instead solder on wire leads to the socket pins and then solder the leads to the points OT pointed you to. You will need to solder the indictor inline with the lead that needs it.

Thanks Dan. Yes L5521 is lost too.

So with the sensor cable, I stick the new sensor on the LCD the other side expose the black and grey wires and solder to points shown by OT? And nothing else?

Thanks both
