Power supply has a continues blink instead of a solid led light.

replace the power pcb board it's faulty

Problem is with one of the circut boards in the tv, It will have to be replaced.

A solid green light means the computer is operating normally.

A solid yellow light indicates the power supply is operating normally but the computer is not processing data.

This could mean there is a problem with the CPu or another component on the motherboard.

((A blinking yellow light indicates the power supply is receiving power from the wall, but not functioning properly.
This generally means the power supply itself is bad and should be tested or replaced.))

A blinking green light means the computer is in standby mode.

You should consider visiting Dell Support and downloading the manual for your

your Dell computer. So use the LED power light codes if your Dell computer has them.

hope this helps

detarch all accessories or hardware connected to the system , then bring out the power pack itself out completely look for a soldering led to test the functionality of the power pack itself if it rotates the fan of its pack by looping the first hole to the third hole cable in the power pack connector that will head into the motherboard. therefore, check the mother board if there is any damage on it like some component if all this is false . then plug the power pack to the outlet and fix the connector of the power pack to the motherboard after detaching both cd drive , floopy disk drive leaving the hard disk and the memory . then change the memory card and press on the system there should be a solution from all this . the problem should be from the Memory not to be able to start up the system but go through those process i have given you before concluding it was the memory ok....


kindly rate this solution......

Here are some troubleshooting steps. From your description, my impression is a bad motherboard.

Solution:
First, disconnect the power cable from the back of the external hard drive:
If the power supply LED continues to blink:

1. Connect the power supply to a different outlet (or instead of connecting to a power strip, connect directly to an outlet in the wall).
   
   
2. If the power supply continues to blink after changing outlets, this indicates that the power supply is defective and needs to be replaced.
   
   
3. If the power supply stays solid, then reconnect to the external hard drive and see if the drive spins.

usually blink code on front gives direction but first thing to do would be to determine if surrounding sustain boards are causing draw on power supply by disconnecting them one at a time from power supply. y is on left looking from back and x is on right looking from back. if led goes solid with either board disconnected check supply voltages and if come up and stay up replace that board. if no change then you would need to verify vs on command coming from logic main to power supply. should be labeled on power supply connector and should be 3 volts. if present replace power supply if not present verify if logic main board sitting underneath signal board has one solid and one blinking led on if verifying normal operation and if so replace small signal board

Had same problem with my Dell Pwoerconnect 2016, power it on and all LEDs light up but nothing works.
The problem was traced to one or both output capacitors ( 10v 680uf ) on the ( tiny ) power supply.
Capacitor symptoms include bulging or rounded tops instead of flat like new one and the rubber plug in base of capacitor protruding.
Capacitors need to be replaced.
I have successfully replaced with 10v 1000uf and 10v 1200uf, both Rubycon and Sanyo brands.
Power to the switch board is now restored and the switch is able to function just fine.
Give it a go and see if it works for your Powerconnect.
