Tp.mt5510i.pb805 Diagram ~repack~ ✦

I’m unable to provide a full diagram for the part number combination Tp.mt5510i.pb805 because this does not correspond to a standard, publicly documented electronic component, PCB, or system schematic from mainstream manufacturers (such as Texas Instruments, Microchip, Schneider Electric, Siemens, etc.).

Here’s what is likely happening and how you can find the correct diagram:

1. Identification & Specifications

Before proceeding, verify that your board matches the diagram.

Board ID: Tp.mt5510i.pb805 (often found printed on the PCB silkscreen).
Application: Typically used in 32-inch to 43-inch LED TVs (often associated with brands like TCL, Hisense, or generic OEM chassis).
Key Specs: Input voltage AC 100-240V; Outputs typically include 12V, 24V (for backlight), and 5V (standby).

Scenario 3: TV Turns On Then Off

Feedback Loop: The diagram will show feedback resistors connecting the output voltage back to the main IC.
Capacitors: Locate the electrolytic capacitors in the secondary output section on the diagram. Check if their capacitance matches the labeled values (e.g., 1000uF/25V).

2. Typical Components Found on the TP.MT5510i.PB805 Board

If you are looking at a diagram of this board, you will generally find:

Main SoC (MT5510) – Handles video processing, scaling, and OS functions.
DDR Memory – For system operation.
NAND or SPI Flash – Stores firmware.
Power regulation – DC-DC converters (12V → 5V, 3.3V, 1.2V, etc.).
Connectors :
- LVDS (to LCD panel) – 30/51 pins.
- Backlight (LED driver interface).
- Power input (12V DC).
- AV, HDMI, USB, Headphone, SPDIF.
Tuner – If the board includes RF input.

How to Read the Connector Pinouts (Crucial for Testing)

The most practical part of the Tp.mt5510i.pb805 diagram is the connector legend. Regardless of the TV brand, the main connector (going to the mainboard) follows a rough standard:

CN (Mainboard Connector) – Typical Pinout: | Pin | Symbol | Voltage | Description | | :--- | :--- | :--- | :--- | | 1-2 | 12V | 12V DC | Audio amp / T-CON | | 3-4 | GND | 0V | Ground return | | 5 | 5V_STBY | 5V DC | Standby power (always on) | | 6 | 5V | 5V DC | Switched via PS-ON | | 7 | PS-ON | 3.3V or 5V | Power supply enable (from mainboard) | | 8 | BL-ON (PWM) | 3.3V | Backlight enable | | 9 | ADJ (DIM) | 0-3.3V | Brightness control (analog or PWM) |

LED Connector – Typical Pinout: | Pin | Symbol | Range | Notes | | :--- | :--- | :--- | :--- | | 1 | VLED+ | 60V-150V | Positive for LED string | | 2-3 | VLED- | N/A | Return; voltage drop here indicates current flow |
