How do i dim the display on my hitachi kc50 clock radio

There is a display button on the unit, if that does not dim the display, there is almost nothing you can do

Vacuum fluorescent display is worn out .. there is no repair. Replacement is the only cure.

I believe the problem is either a faulty light sensor the unit has to dim the display when the lights dim since it was designed for bedroom use with alrms and snooze button. or it is simply a failure in the circuit that drives the LCDs. Mine has been dim for a long time but I can still see just enough to adjust the sound settings. I tune and set stations by sound. so the display has not been an issue since we do not use it for a clock or alarm. I doubt there is a fix for the dim display.

From the manual:

This alarm clock radio features an adjustable display backlight, with dim, medium, and bright settings. To select a backlight setting, press the Snooze/Dimmer Bar until the desired brightness is reached.

Mine is dim also. Apparently sending it in for repair is not an option.

Unfortunately, the CD740 radio has reached end of service life. Parts are no longer available & we cannot repair them. We apologize for any inconvenience. If you need further assistance, please call us at -800-367-4434, Monday - Friday 9AM to 6PM central time.

TRY........with radio on and set on "AM", hold "Clock" button about 7 seconds and let up - bringing a setup menu. Using tuning knob,scroll to "Hardware". Press tuning knob in, bringing up contrast menu. Press tuning knob in, bringing up "contrast level". Turn tuning knob counter-clockwise to "00". Brightness, dimming level should be "170". Turn radio off to exit, then adjust "Dim" button to your liking.

I just got a similar model at Big Lots a few months ago. A T439S. There some funky stuff they do with those displays it could be that the lamp is wearing out. 7 years is good life for them.

A-ha! Those manuals sure do come in handy sometimes. I found the solution. In addition to functioning as a snooze button for delaying the alarm, the snooze button is also a brightness button for the time. If you press snooze one time it changes the time brightness from bright to dim, press it again and it goes from dim to motion sensitive only, press it again and it returns to bright.

I just tried this and resolved my problem. I hope it helps you as well.
Enjoy!
