Service Manual _hot_ - Tp.ms3458.pc757

Check the large filter capacitor (450V). It should hold roughly 300V DC (in 220V countries) or 160V DC (in 110V countries).

Supports both single and dual-channel 8-bit/10-bit FHD (1920x1080) and HD (1366x768) resolutions. Voltage Distribution and Test Points

Verify continuity on the HDMI lines. If shorted, the main chip may be damaged. 4. Where to Find the TP.MS3458.PC757 Service Manual

Reprogram the SPI Flash IC (usually an 8-pin 25Q64 or similar chip) using a programmer like the CH341A.

Official service manuals for these generic boards are rarely published by manufacturers. However, you can obtain equivalent documentation through these sources:

Short Circuit (Blown Driver): Voltage stays strictly at 12V and never boosts. Inspect the boost MOSFET and the driver IC. Backlight Current Modification (Proactive Repair) tp.ms3458.pc757 service manual

| Test Point | Standby (V) | Power On (V) | |------------|-------------|---------------| | +12V_IN | 0 | 12.0 | | +5V_STB | 5.0 | 5.0 | | VDD_CORE | 0 | 1.2 | | DDR_VDD | 0 | 1.5 |

Measure the voltage across the LED output connector during power-on. It should spike high (e.g., 60V–100V+) and then slowly drop down if the LEDs are open-circuit. Check the large filter capacitor (450V)

Ensure 1.2V Core and 3.3V Flash rails are perfectly stable.
