How do I check the printed circuit board? (Slew-Cursor defect)

[Muts]

I have a problem with my TM Throttle. The Slew-Cursor does not function. Only the Center Button gives a Signal.

I replaced the Cursor but the problem is still there. My suspicion is a defect on the circuit board. Have anybody an idea, how I can check the curcuit board?

Thrustmuster offert me a new board, but I will be sure, there is realy an defect.

I checkted (continuity check) the cable from the Board to the "Mainboard". There was no issue.

 

Thx for any ideas!

Here You will find some information about the I2C Connection. If you had a logic analyzer you could check if the signal is transmitted correctly.

 

 

When you fixed your PCB, it would be a great oppertunity to replace the unit with a usable alternative.

 

If you make a detailed pic of the PCB (so I can read the writing on the IC's), I might could give some tipps. Do not want to disassemble my throttle tonight ;)

:)Thanks for your support. Following a detailed pic.

Alright. I assume the rest of the throttle is working without issue?

You got a Voltmeter/Ohmmeter?

The connector which is not plugged in. Pins from Right to left

1: 3.3V -> You should be able to measure this voltage. Use the Via Bottom Left as Ground

2: I2C SDA -> This will connect directly to the connector which goes down into the throttle. Check with the OhmMeter

3: I2C SCL -> Same as above. Check the connection.

 

If this is all correct, unscrew the bottom of the throttle and check if the flat cable is connected into the mainboard. Let's hope your cable doesnt have a damaged wire.

Just saw you are also from Switzerland :D
