Short diagnostic checklist and safe next steps — expands on points from / (buttons) and / (control/digital board).

Start with simple isolation tests: swap the power cable and outlet with the working monitor, and remove any power strip or surge protector. Disconnect the video cable so the monitor is powered but has no input. With the monitor unplugged, press-and-hold the power button for 10–30 seconds to bleed residual charge, then plug it back in and power it on. If the set still turns on/off with no video connected and after swapping cables, the fault is almost certainly internal (power board or digital control board) rather than the PC or signal.

Symptoms that point to internal board failure: repeated on/off cycles, clicking sounds, backlight flashing while power LED blinks, or completely unresponsive OSD/buttons. If you are comfortable with basic electronics and safety (unplug first, wait several minutes), open the rear to inspect the power/control boards for visibly bulging or leaking electrolytic capacitors — a common, repairable fault. The small daughterboard behind the front buttons and its ribbon cable are another likely culprit: reseating that connector sometimes restores button response without further work.

Safety and next steps: do not work inside the monitor if you’re not experienced with mains voltage and charged capacitors. If your tests point to an internal fault and you’re not confident doing repairs, get a repair quote and compare it to the cost of replacing the VX2235WM — older panels are often cheaper to replace. If you plan to proceed, note the exact model and any LED blink pattern or sounds and post those details; they make diagnosing which board or part (or simple ribbon reseat) is needed.

It's not the buttons, it will be a fault on the digital control board within the monitor. Unless you are an electronics expert you will have to get it professionally repaired.
