Here’s what you can do:
When the TV is powered on, these voltages should be present at the labeled test points on the board. Use a multimeter set to DC volts, grounding the black probe to the chassis. Test Point Expected Voltage Common Symptom if Missing No display, backlight stays on White screen or no display 20V to 30V Slow motion picture or no display VGL / VOFF -5V to -10V Slow motion, colored lines, or distorted picture White display or washed-out colors No picture or unstable display 3.

While a single official "datasheet" PDF for the entire board is rarely public, technician-sourced data confirms the following details: IPS Alpha 19100165 (MDK336V-0N) T-Con Board - ShopJimmy Here’s what you can do:
Find a replacement board based on your specific TV model number. Walk through a voltage test if you have a multimeter handy. When the TV is powered on, these voltages
White or Faded Screen: A completely white screen or a "washed-out" image often indicates a failure in the voltage regulation circuit of the T-CON.
While primarily for IC chips, entering MDK336V here may yield the datasheet for the primary controller chip on the board. This is a good alternative if the full board schematic is missing.
Disclaimer: Repairing electronic components involves handling delicate circuits. Ensure the TV is unplugged and capacitors are discharged before handling the T-CON board.
