SA1012 contrast fault and solution

1. Problem details 

2. LCD details

3. Solution    

Incidental, these Bias levels might be different on certain clusters. This will result in less sharp images, or less contrast. If so, they can be slightly adjusted by soldering a resistor to a +5V, ground, or -15V(or -12V) point.                     

                                             

                                                                                                                                                                                                                                                             

For example, if you got a LCD show contrast fault,

Step 1. Power on the dashboard, measure the voltage of V1 to V5

            

Step 2. Compare to the design Bais voltage and find out which one is much different.  

Step 3. Adjust the measured volt close to Designed BIAS Levels.                     

For now we want to add V2 more 0.20Volt, it can find for V2 need to add a 2.1K ohm resistor.
