I have a digital alarm clock that has a large LCD display. A while back some of the sections of the number on the clock went out. The problem persisted after changing the batteries.

The way the sections of the display go on and off has no specific pattern. They are not the same sections that behave this way. The electronic board of the clock has an unidentified IC and a couple of transistors, capacitors.

Any ideas are welcome.

Poor connection somewhere. Check solder joints, reseat any plug-in cableing, etc.
