I would not suggest that. Most systems are matched to the control board by flashing the system software. best to have a qualified tech do it. If you try to flash them and it fails the unit is usually toast.

Check engine light, not registering temp

Hi, You'll need to get the trouble codes read. I'm guessing the code probably has something to do with your engine coolant temperature sensor or the engine coolant temperature sending unit.

2001 6cy camry has check engine light on. code 1135

Hello. You can do this yourself.

You need to replace the Air-fuel sensor. I would strongly suggest that you purchase and install a Toyota sensor, however. The "aftermarket" sensors do not have the exact same voltage signals, and will not rectify the condition; the light will remain on. We see this quite a bit in our service dept.

We hope that this helps you out.

Large light blue spot when TV is on

It is a defective light engine and is not a user replaceable part. In most case the part will cost close to 1000 if not more.

Its not a cheap fix, as the part alone costs over 300usd I would leave it to a professional myself.
