If your Pioneer Monitor has no power and both the red and green LEDs are unlit, the cause might be a cable disconnection. Check if the connection between the POWER SUPPLY and PANEL IF assemblies is properly made.
Why Pioneer Monitor has no power (green LED not lit)?
If your Pioneer Monitor has no power and the green LED is not lit, it could be due to a defective 114-pin FPC. Check if the FPC is broken or not securely inserted.
What to do if Pioneer PDP-505PU Monitor has abnormal screen (Data of every other dot are abnormal)?
If your Pioneer Monitor screen is abnormal, with the data of every other dot being abnormal, it could be due to a defective 114-pin FPC. Check if an abnormal area in the screen changes when the FPC connected to the address corresponding to the abnormal area is replaced with the one corresponding to the next address.
What causes abnormality in a one-eighth area of the Pioneer Monitor screen?
If there is an abnormality in a one-eighth area of your Pioneer Monitor screen, the cause may be a defective infrared receiver. Check if a pulse is output when the key corresponding to Pin 2 of the CN4852 is pressed.
What to do if the Pioneer PDP-505PU power is sometimes interrupted?
If the power to your Pioneer Monitor is intermittently interrupted, the cause may be defective system cables. Check to ensure that all system cables are securely connected.
Why is the Pioneer Monitor remote control unit not effective?
If the remote control unit for your Pioneer Monitor is not working, it may be due to cable disconnection. Check if the cables are disconnected or not securely connected.
What to do if Pioneer PDP-505PU Monitor power is interrupted, and red and green warning indications appear?
