How do I get the display screen to illuminate?

If the LCD screen on your JL Audio JX250/1 amplifier is not lighting up when you turn it on, there may be a few possible causes:

• Faulty power connection: Check that the amplifier is receiving power by verifying that the power light is illuminated. If the power light is not on, there may be a problem with the power connection, fuse or wiring.
• Blown backlight: If the power light is on but the LCD screen is not illuminated, the backlight may be blown. In this case, the LCD screen may still display information, but it will not be visible without a backlight.
• Faulty LCD screen: If neither the power light nor the LCD screen are illuminated, there may be a problem with the LCD screen itself. This could be due to a faulty display panel, cable or connector.

It is normal and indicates to avoid driving in this zone in any gear.

your problem is a faulty ccfl BackLight Inverter, the display uses the backlight to illuminate the lcd screen, the inverter is used to illuminate the cold cathode light in the back of ther lcd theirs countless places to laern about it on google

try checking the illumination light on the back of the radio if that doesnt work then try looking at the red ignitionswitch wire and make sure it is connected to the 12vt constant (the yellow wire)

in most cases the fibre ribbon gets worn out.
you can try a local cellphone repair shop, or sony service if you can afford it.
the ribbon needs to be replaced.
