What's the actual question ? is it a dry joint fix ??

I have canbus fault everything points to this part. It's been fixed before it seems so was hoping to bake it but don't think the screen can handle it

This has the canbus resistors on it. I would use a magnifying glass and look at most soldered joints now that you have it out. It would be a "cold" joint, usually cracked all the way around a hole etc or on one of the chips. Hope you are good at fine soldering.

If you're trying to reflow the solder you'll probably need to be somewhere just over 180C for about 20 minutes.

Forget the oven, unless you want to remove everything plastic from the PCB board, that green connector at the top left will melt way before the solder becomes a liquid. You could protect parts with heat resistant tape and use a heat gun. The problem with heat guns is your likely to warp the PCB if you dont heat it all and let it all cool down slowly.
As already suggested it is better to find the dry joint /s and repair them all with new solder.
Or send it away for a proper repair to those that do them all the time.

Hi
Once again apologises in forgetting to tell u to disconnect the battery before doing a canbus OHMs test
Please let us know what u find after testing the following pins on ur OBD2 port using a multimeter
Test probe to pin 6 other probe to pin 14 , read ohms
Test probe to pin 3 other probe to pin 11, read ohms
Hope it helps

LCD's screens don't like it much above 100°C
Not sure if that is LCD

I happened to have an IPC sat on the shelf here, so if it helps, these are the four resistors that form the terminators for the two CAN interfaces. It's not certain, but they would be likely culprits.

The two resistors in the centre, marked 62R0, next to the IPC connector.

R36, R37 marked on the silkscreen, again both marked 62R0, near the middle of the board.
If you've got a small soldering iron, you can just reflow these four with low risk of causing any more damage. Lead -free solder always looks a bit like a poor solder joint anyway, so I would just reflow them with a little leaded solder so it flows nicely. If you aren't used to surface mount components, heat the solder in the joint, not the component, and only one end at a time so it doesn't float away. Find some electronic junk to practice on - ebay is a good source of it I find
