TROUBLESHOOT

• Verify the state of TV set. Switch the TV on ,then verify the LED color. Red is standby state and green is working state.
• Checking Supply Power. If the color of LED is yellow, the power supply for signal board, N801 supply 5V and N802 supply 3.3V,N804、N806 supply 3.3V power (Test the PIN 2).N805 supply 2.5V(Test the PIN 2),D803 supply 8.3V,V401 and V402 supply 1.8V. All these are on main IC N401,N501.
• After turning on the power, if blank screen appears (no back light lamp), just press POWER button several times, if blank screen still there. Check if the voltage of every power supply is normal.
• Check if the crystal oscillator X501(14.318180MHz) X401(24.576MHz) oscillate or not, and oscillate frequency is right or not.
• Back light control signal (BKLON) of XS801 has high level (about 2.5V) or not. If not, check whether fault soldered or short circuit happened, 6) If back light lamp is on while there is no display, check N407 and N501’s reset circuit and the output of the oscillator to confirm the CPU and SCALER are working or not. If RGB is abnormal, check N501;If RGB is working correctly and the other channel is abnormal, check N501.

Verify the state of TV set:  switch the TV ON by “Power on/off” switch, Then verify the LED color of touch button. Red is standby state and blue is working state.

Checking Supply Power:  If the color of LED is green, the power supply for signal board. F801 supply 5V, N804, N803 supply 3.3V power(Test the PIN 2). N808 supply 2.5V(Test the PIN 2), D806 supply 8V, N804 supply 1.8V. All these are for main IC N001, N401, N504.

Digital signal part:  Turn on the power => N001 RESET and IO port initialize => N504 electrify, reset, initialize => Turn on back light lamp => Successful start And LOGO display.

• After turning on the power, if blank screen appears (no back light lamp), just press POWER button one times, if blank screen still there.
• Check if the voltage of every power supply is normal.
• Check if the crystal oscillator Z001(22.1184MHz) Z501(14.318MHz) Z400(24.576MHZ) oscillate or not, and oscillate frequency is right or not.
• Back light control signal (BKLON) of XS806 has high level (above 3V) or not, if not, check whether fault soldered or short circuit happened.
• If back light lamp is on while there is no display, check N001 and N504’s reset circuit and the output of the oscillator to confirm the CPU and SCALER are working or not. If RGB is abnormal, check N504;If RGB is working correctly and the other channel is abnormal check N504.

White calibration adjustment.

• Receive black or white signal under AV or PC mode, adjusting brightness and contrast to set the brightness to 5 Nit in dark area and 90 Nit in bright area.
• Adjust white balance. 
• Enter factory menu, select User RGB Menu
