If the key input is not effective, check the connection of the system cables.
What to do if the power is interrupted, and the red and green warning indications appear on the screen of Pioneer Monitor?
If the power is interrupted and the red and green warning lights appear, check if the system cables are securely connected.
Why Pioneer PDP-434PU Monitor has no power and both red and green LEDs are lit?
If there is no power and both red and green LEDs are lit, check if the TRAP switch is properly set.
Why Pioneer Monitor power is (sometimes) interrupted?
If the power is sometimes interrupted, check if the unit works properly when detection of the TRAP switch is canceled.
How to fix Pioneer Monitor with no power (both red and green LEDs unlit)?
If there is no power and both red and green LEDs are unlit, check if the connection between the POWER SUPPLY and PANEL IF assemblies is properly made.
Why Pioneer PDP-434PU Monitor has no power (green LED not lit)?
If there is no power and the green LED is not lit, check if the FPC is broken or not securely inserted.
What to do if there is abnormality in a one-eighth area of the screen of Pioneer PDP-434PU Monitor?
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 to do if Pioneer PDP-434PU has abnormal screen (Data of every other dot are abnormal)?
Check that an abnormal area in the screen does not change when the FPC connected to the address corresponding to the abnormal area is replaced with the one corresponding to the next address.
