This specific T-Con board is manufactured by Samsung and is predominantly found as an internal part within their 32-inch LCD/LED TV models, such as the , UE32D4000 , LN32D403 , and LE32E420 series.
Measure voltage on both sides of the fuse relative to the chassis ground.
Accurate voltage measurement is the first step in troubleshooting. The following points, typically present on most T-Con boards, are essential for the board to function:
Let’s say you have a dead 32-inch TV with the 32AP11S4LV1.1 board. Here is how to use the schematic diagram to diagnose it. 32ap11s4lv1.1 schematic diagram
The is a specific type of T-CON (Timing Controller) board manufactured by Samsung. This small PCB serves as the vital bridge between a television's main processor and its LCD panel. It is responsible for generating all the essential timing signals and voltages required to "drive" the screen and create a viewable image.
: The panel receives clock feeds on both its left and right boundaries. A short usually manifests on only one side.
This specific board version is frequently discussed in repair communities regarding two main issues: This specific T-Con board is manufactured by Samsung
The most reliable source for this schematic is through online communities dedicated to electronics repair, especially Russian and Eastern European forums where this board is commonly discussed.
The T-CON board generates several specialized voltages required by the LCD panel. If any of these are missing or incorrect, the screen will malfunction. The schematic helps locate test points for crucial rails like:
(Low-Voltage Differential Signaling) input to receive video data from the mainboard. Components : Often features the DC-DC converter IC. Common Issues & Troubleshooting The following points, typically present on most T-Con
Unlike open-source hardware, these schematics are proprietary. However, you can find them through:
(-8V) : Gate Low voltage. This negative rail continuously discharges or switches off the TFT rows. HVDDcap H sub cap V cap D cap D end-sub (7V) : Half- AVDDcap A sub cap V cap D cap D end-sub
: Common reference voltage for the liquid crystal cell matrix. Corrects flicker and optimization. 3. Common Failure Modes and Troubleshooting Steps
