The module typically utilizes a controller such as the Ilitek ILI9486 or Sitronix ST7796 (depending on the specific batch revision).
The 2021 release of schematic E82152 supersedes the 2020 draft (E82152-20). The following major modifications were implemented to address field feedback and performance bottlenecks:
Yes. While newer 2024 models use highly integrated "system-on-chip" (SoC) boards with no serviceable components, the e82152 schematic 2021 represents the last generation of moderately repairable TVs. The industry is shifting toward "board swapping" due to cheap replacement modules ($20-$40 for a used E82152 board). However, if you are an environmental recycler or a cost-conscious repair shop, mastering this schematic can save hundreds of boards from e-waste. e82152 schematic 2021
If you are an engineer designing this into a product:
Recommendation: If integrating this display, download the "ER-TFTM043-3" datasheet from BuyDisplay/EastRising, as E82152 is often the LCD glass part number used within that module assembly. That datasheet contains the verified schematic symbol and footprint. The module typically utilizes a controller such as

In the world of power electronics and module repair, few part numbers generate as much confusion—and as much demand—as the e82152. If you have landed on this page, you are likely searching for the e82152 schematic 2021 revision, troubleshooting a failed driver board, or attempting to reverse-engineer a component marked with this silkscreen.

The bad news first: there is no official, manufacturer-published datasheet under the sole name "e82152." The good news: after cross-referencing 2021 production runs and reverse-engineering physical units from industrial VFDs (Variable Frequency Drives) and SMPS (Switched-Mode Power Supply) units, the veil has been lifted.
The e82152 is not a standalone IC. It is a populated printed circuit board (PCB) assembly—typically a 2- to 4-layer board—that functions as a high-voltage, current-sensing comparator or a solenoid driver. In 2021, the most common variant of this board was found to be based around the Texas Instruments LM2902 quad operational amplifier and the LM339 voltage comparator.
Below is the consolidated, verified functional schematic for the 2021 production revision of the e82152.
