TFP410: Dim Display Issue

Part Number: TFP410

Hello,

We are using TFP410 in our design, we had configured it in "24-bit, Single-edge, Rising, Single Ended Mode" i.e. "VREF=0.75V, BSEL=1, EDGE=1, DSEL=0", Disabled the I2C "ISEL=0", and driving it in 18bit mode by grounding the unused pins, We had probed HSYNC on HSYNC Pin, VSYNC on VSYNC Pin, BIAS on DE Pin, PCLK on IDCK+ Pin [Grounded the IDCK- Pin] and Data Signal on Dx pins, Signal looks to be fine.

But the issue we are facing is the overall Display is Very Dim, I have attached the snippet of the schematic and the snap of the display. Hoping for reply and resolution soon.
