Fix Fault Digimate

Just bought a Digimate L1918 (second-hand) and it says 'no signal' on the screen - what am I doing wrong??

my digimate monitor has a faulty pcb number CRT51B can it be repaired??

my monitor refuses to start up the switch starts green and the screen lights up then the start button changes to orange and the screen goes black??

I've got a Digimate 17" model L-1715 LCD Monitor. When you plug it in and switch on, the power light comes on red, but no display. After two or three seconds, the power light dims, but still nothing h ... more

digimate comes on but goes off right away l-1715
