The is a critical T-Con (Timing Controller) scaler board frequently found in 32-inch Samsung LED and LCD televisions. This board acts as the intermediary between the TV's mainboard and the LCD panel, translating video signals into the specific electrical pulses required to render an image.
Typically -5V to -7V, used to turn off the pixels.
Usually around 15V–17V, powering the source drivers.
Issues like a or jumping picture are often traced to the CKV (Clock Vertical) and CKVB (Clock Vertical Bar) signals. Technicians often perform a "tape cut" or "track cut" modification on these specific lines to bypass internal panel shorts when a full panel replacement isn't viable. Common Troubleshooting Steps
This board is standard in models such as the Samsung UE32D4003 , UE32D4000NW, and LE32E420E2W .
Before attempting a repair, confirm that your board matches this specific PCB number. While many T-Con boards look similar, using an incompatible version can lead to permanent panel damage.
When troubleshooting display issues like a , horizontal lines, or a "no picture" condition (where backlights are on but the screen is blank), the 32AP11S4LV1.1 schematic diagram becomes an essential tool for identifying voltage rail failures or signal interruptions.
