If the primary side is alive but there is no output, look at the secondary diodes. A shorted rectifying diode on the +12V line will force the PWM IC into hiccup/protection mode. Symptom 2: Red Standby LED Stays On (Won't Turn On)

If all voltages are correct, the SPI Flash memory chip (usually an 8-pin IC like 25Q64 or 25Q128) likely has corrupted firmware. You will need a USB programmer (such as the RT809F or CH341A) to re-flash the correct firmware binary file onto the chip. Symptom 3: Sound is Present, But No Picture (Black Screen)

To prevent future backlight failures after replacing LED strips, locate the current-sensing resistor bank (low-resistance SMD resistors connected to the source pin of the backlight return MOSFET). Removing one or two of these parallel resistors increases the resistance loop, reducing the current driven to the LEDs by 10% to 20%, which drastically extends their lifespan without visibly affecting screen brightness. If the primary side is alive but there

Missing = Processor will not boot; power indicator stays red. Missing = Boot loop or completely dead logic block. Panel VCC (LVDS Fuse) +5V or +12V DC Missing = Sound but no picture; screen glowing blank white. Troubleshooting Common Faults Using the Schematic Symptom 1: Dead Board (No Standby Red LED)
