1) Is the TV plugged directly into an outlet or is it plugged into another device, such as a cable box or audio receiver? If it is, try plugging directly into a wall outlet. Sometimes, devices like cable boxes don't provide enough current to power on more powerful newer TVs (like Plasma, LCD, etc) .
2) Check the manual to see if the flashing LED is a code for something you need to troubleshoot. The number and color of flashes may correspond to a problem that may or may not be easily fixed.
Hello. Hope you got working already. But if you're still having the problem, unplug the power supply (the small black box behind the printer where the power cord is attached) with the other end still plugged in to a known working power outlet. Look around the black box, it should have a green LED on around the silver contacts. If not, properly secure the power cord by unplugging and plugging it back in. Otherwise, you got a defective power supply. Try not to use extensions or power strips, plug printer straight to the wall power outlet or plug it to a different known working power outlet. If the power supply is working fine, plug it back in the printer in a correct position. Properly insert it and make sure it pushed all the way in the printer. If you're still getting all blinking lights once plugged in, your printer might be damaged by the the lightning strike. If that's the case, you can call Lexmark and ask for assistance with that. Well, these are the troubleshooting steps you can do to determine where the problem is. Good luck!
it could be th epower supply and it could be the monitor.
power ON button should not flash orange regardless what you do. it should stay green. then orange. not orange to green to orange.
try the monitor on another PC if you can fine one.
the other thing is are the 2 monitor similar (CRT to CRT and LCD to LCD), you can't mix the the two, they will work but need different video driver to function correctly.
This is an easy fix so here you go nice and simple:
Problem: Your motherboard circuit has been cut.
Causes: Power disconnected during operation. Power outage or short in the surge protector.
Symptoms: Flashing green light on both motherboard and power supply. System will not power on.
Step 1: Ensure that both the power supply and the motherboard lights are flashing green, not solid or off.
Step 2: While the power is on, disconnect the power supply from the motherboard. This connection is the largest of the connections and should be listed as the 'P1' or 'Primary' power connection.
Step 3: Wait until the green light on the motherboard stops flashing and check to ensure that the green light on the power supply is now solid. If it is not solid, disconnect the power to the power supply and wait until the light turns off completely. Then reconnect, it should be solid now.
Step 4: While the power is on, reconnect the P1 connection to the motherboard and you should now see that the light on the motherboard is solid.
Step 5: Power on your PC. The problem should not persist.
Warnings: If the power supply light remains flashing after you have restored power to it while it is disconnected from the motherboard, it may be a system failure in the power supply itself requiring replacement. Always be careful when working with an active or live power machine.
The part where you see some color bars and blinking green led is what we call MONITOR SELF TEST. A diagnostic pattern consisting of four colors (red, green, blue and white) appears, and the LED flashes slowly. this happens when signal cable from the monitor is disconnected from the tower and leaving the power chord for the monitor plugged in. If the monitor works properly on a different computer. then its a problem with the computer's video card sending out signal. im 85% sure that its a problem with your video card.
