on the secondary side, measure the voltage on the primary filter capacitor (should be around
Handles video processing and Android OS. RAM and eMMC Storage: Runs the TV firmware. 2. TP.MT5510I.PB805 Diagram and Functional Sections
Feedback mechanism for voltage regulation. B. LED Driver Section (Backlight Driver)
Check F1 Fuse, Main Filter Capacitor, PSU IC, and Standby voltage ( Corrupted Firmware (needs USB flash), or CPU failure. Check 1.1V1.1 cap V Core voltage. Sound, No Picture Tp.mt5510i.pb805 Diagram
This is rarely a hardware component failure and is usually a firmware corruption issue within the EMMC chip.
To access factory settings (proceed with caution):
Built-in Wi-Fi, RJ45 Ethernet, 2x HDMI, 2x USB, AV Input, Coaxial, and RF Tuner on the secondary side, measure the voltage on

Integrated next to the primary power stage, this section bumps up the voltage to meet the demands of the TV's LED strips.
Technicians often need the diagram to identify recovery pins for forcing a software update. Check 1
Includes WiFi, Ethernet, HDMI, USB, and AV inputs. 2. Schematic & Wiring Information
| Test Point | Standby | Operational | | :--- | :--- | :--- | | | 0V | 3.3V | | BL_ON | 0V | 3.3V | | PWM_DIM | 0V | 0V–3.3V (varies) | | VCC_PANEL (12V) | 0V | 12V |
Stepped-up voltage can be measured at the cathode of the secondary boost diode. If this matches the 12V rail exactly while the TV is "on", the boost circuit is not switching. Common Faults and Troubleshooting Solutions Probable Cause Diagnostic & Repair Step Dead / No Standby Light Blown fuse or failed primary PWM circuit.
The most critical part of the diagram for repair technicians is the pinout of the main connectors.
