Using a multimeter, technicians check for VGH (typically +20V to +30V) and VGL (typically -5V to -10V). If these are missing, the screen will likely remain blank or display a slowly fading image. Where to Source Parts Where to Source Parts Distorted or "washed out"

Distorted or "washed out" colors are often caused by a failing Gamma IC (AS15-F or similar) which manages the reference voltages for color accuracy.

The T-CON board acts as the "brain" of the display panel. It receives video data from the television's main logic board (via LVDS cables) and translates it into the specific timing signals required by the Source and Gate drivers to activate the individual pixels on the LCD. Used extensively in the Sony KDL-40R470A and related 40-inch LED/LCD models.

Typically includes a Samsung or Sony proprietary timing controller chip 12V (VCC), VGH, VGL, and AVDD (Analog Supply) Status Indicators
