Digital_Igloo

Please help. A drink got spilled on my Helix LT and the display is messed up. It's like the brightness is so far up everything is washed out and unreadable. Unit functions perfectly (audio, usb, etc). The splash screen looks fine, it's just everything else is messed up visually. I had my local Line6 repair center look at it and he replaced the LCD UI board but that didn't fix anything. I'd like to avoid just randomly replacing circuit boards. Could you please offer a hint on what might be messed up? It seems the display board is fed by the MCU-DSP board. It sucks having an $1100 door stop. THANKS in advance.
