Hello All,
I powered up my KRC2sr controller this morning, the teach pendent and external monitor are always black. I tried to power up several times, there are two different scenario.
Scenario 1-
-the teach pendent and external monitor are always black
-no beep sound from motherboard
-the led on keyboard is off
Scenario 2-
-the teach pendent and external monitor are always black
-1 long beep with 2 short beeps, pause around 4 seconds follow with 2 short beeps sound
-the led on keyboard is on
The 3 fans are working.
Scenario 1 looks like the BIOS doesn't work at all.
Scenario 2 looks like the video card is bad.
Could anyone give me some advice to diagnostic this problem?
Thanks.
