Tip: The max point reward for answering a question is 15.
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.
I have the same problem with my Trimble Juno SB. It just happened today. But when I plug mine in to a power source the LED is green. But when I hit the power button it flashes red one time. I have tried soft and hard resetting it. And I even tried the 'restore factory settings' reset. Nothing works, It just stays off. The screen never comes on.
Did no one else read the question? It isn't for a laptop. It is for a Trimble Juno SB.
I suggest that you remove the battery and use the charger only in turning on your computer. If it turns on just fine without the battery then you would need to replace the battery. If it doesn't then it's either the motherboard or the charger which has a problem. David
Try to power drain it. Unplug all the power related devices that are connected, like a monitor data cable or external printer, just unplug all the cables in the back after you shut down your computer, press the power switch of your computer and keep it pressed for about 45 secs, release it, plug everything back and check it if its working. As well double check if that particular socket is usable, plug something else in to see if its working.
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!
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.
sounds like a dead battery. Plug the origional charger into it and the front led (below the flash) should flash red. If the red led in the back of the camera flashes or stays lit, then you have the wrong charger plugged in. (the camera won't power up if the back red/green led is on when plugged in)
