Note: If VGH is below 22V or VGL is above -4V, the T-Con will fail to open the panel's transistors, resulting in a white screen.
A: No. The new EEPROM will be blank. It must be programmed with the correct .bin firmware file for your specific LCD panel using an EEPROM programmer. Swapping it without programming will result in no picture or a severe display malfunction.
Dual Flexible Flat Cables (FFC) to the source driver PCBs (source cobs)
If you cannot find a free PDF, professional sites like or Doctor Reparacion typically sell the full PDF for $5-$10. Given the cost of a new TV, this is a reasonable investment. t-con mdk336v-0n pdf
These chips work together to take the low‑voltage differential signaling (LVDS) data from the main board and convert it into the precise control signals that drive each pixel on the screen.
A: Yes. Schematics are a universal language. Focus on the reference designators (R1, C2, IC3) and voltage notations. Component values are numeric.
Based on the part number , this component is a T-Con (Timing Controller) board , commonly found in LG and Vizio 4K LED televisions (typically in the 49" to 55" range). Note: If VGH is below 22V or VGL
Most T-Con boards have a tiny, surface-mount fuse near the LVDS connector. The PDF will show its exact location (often labeled F1 or FB1 ) and its rating (e.g., 3A, 4A). A blown fuse is the most common failure.
: Between 13V and 20V . Missing voltage can lead to vertical color lines or a white display. Common Failure Points IPS Alpha 19100165 (MDK336V-0N) T-Con Board - ShopJimmy
If any capacitor reads close to 0 Ohms on both sides, it is shorted and must be desoldered and replaced. Step 3: Test Voltage Sequencing It must be programmed with the correct
If you have an EEPROM programmer (like CH341A), you can:
Includes a main logic chip, DC-DC converter IC, and SMD fuses (often marked "162 NCC"). Known Compatible TV Models The board is found in several legacy 32-inch display units: Panasonic: TC-L32C12, TC-L32X1, TH-L32X10M, TX-LR32S10. DP32649 (Version P32649-06). HDLCD3212. LED37T28P (with HE370BF-D01 panel). Troubleshooting & Repair Tips
: Power down the device. Unclip and clean the contacts of the flat ribbon cables leading from the T-Con board to the panel source-driver boards using isopropyl alcohol.
Replacing the board is straightforward if you have basic electronic repair skills.
While the Internet is cluttered with low-quality scans and malicious links, focusing your search on the LCD panel number and using reputable forums like Badcaps or ElektroTanya will yield results. Once you have the PDF in hand, remember the golden rules: check the fuse first, verify VGH and VGL second, and then move to gamma correction.
