Hi All,
I am having a bit of bother with the following two components:
TC7106CPL 3.5 digit display driver:

JX5094PHT 3.5 digit LCD display:

Now, I have connected up both components with the configuration as shown in Figure 10-8 as found here:

The problem I am having is that the LCD constantly displays all of the LCD segments, as if the test pin was active. From the datasheet, it says that pulling this test pin to +Vsupply will do this, but I have not got this connected to anything. Using a multimeter, I found that the voltage on this pin was around 9Volts (n.b Vsupply is 15V)
I am struggling to understand what has gone wrong and I thank all in advance for assistance.
Cheers,
Paw
