No beeps are heard, no CPU fan is turning on, only blinking yellow light. This brand usually experiences this problem.

  1. First, check the power supply. Disconnect connectors from the board and make a jumper wire for the green wire to any black wire. If the PS fan does not spin then it's busted, else proceed below.
  2. Reconnect connectors except the one with 4 wires, 2 yellow and 2 black, then switch on. If CPU fan turns on then you have a bad processor.
  3. If the fan is still not turning on then check the USB port pins for short circuit.. disconnect it from the board and switch on.
  4. Do the same with other hardware connected to the board.
PS: The metallic casing of computers must be connected to the common ground of the power utility to protect it from stray currents that result to damage of sensitive components such as processors, memory and hard disks.

I have a 36'olevia HDTV.......it has a detachable power cord and it also has a power switch in back. When I plugged it into the wall,turned on the power switch, and pressed the power button, I got no


The light is likely the standby light if it is on when set is off and goes out when set turned on or changes color when set comes on.

The fact the light is on should rule OUT the main fuse for the set, most likely the problem is the power supply itself inside the set

The Standby supply is part of the main power supply and when set is plugged in and off it runs 7/24.

Have you had problems where the set was "hard to turn on" or you had to try to turn it on several times before it would stay on?

Not working or coming on


Check to make sure the power cord you are using is getting 120 volts and that it is plugged in properly to the pc. If you are sure your power cord is powering to 120 volts, plug it in to the computer and see if the power supply light (in the back of the computer) is coming on. If it is, then the power supply is good, if not, you need a new power supply unit. If your power supply does not have a power light on it, listen for the cooling fans to come on when you press the power button, if they don't, it is very possible that the power supply is bad and will need to be changed.

The TV will not turn on. No power light


Check the power supply; look for bad caps with leaking/bulging tops, check to see if you have standby +5vdc at the power supply connector, the front red indicator will not be on if you do not have this +5vdc standby voltage due to shorted out Q7 and ZD4.

Make sure the switch on the back of the power supply is set to the position that has the line on it. If you still can't get any power, then try another known good power supply, if you still don't get any power then you know the motheroard is bad.

Computer will not turn on


May sound strange, but is the power supply switch in the correct position?
If the button is pressed, makes your continuity test, and not even the fans come on, check that the switch jumper has not come loose from the motherboard, and finally, if the motherboard is plugged in and no fan comes on when you push the power button, there may be chipset damage from an electrical surge or overheating.
In this case, a new mobo is your only option.

it could be your power switch, veriy that it isnt the power supply by

1.) un-plug it from the main board
2.) look at the main board connector(one coming of the power supply)
3.) you should see green wire and next to it a black one
4.) using a paper clip bridge the too wires
5.) if it works proceed to net step if not get a new power supply

to check case switch and board switch

1.) plug in power supply to main board
2.) look at the pins where the power button connects to
3.) using a metal object (blade screw driver) bridge the pins

if the board should start up>
then its your power button on the case that is bad, you can try to repair it, chage it or buy a new case,

if it doesnt work.
1.) ensure that jcms(jumper to flash the bios) is set correctly
2.) unjack each drive one at a time to see if any is causing stalling
3.) get a new main board

Power supply light has blinking green light


If the power box is bad, The computer will not come on. if you only get a green light, you would need to start with replaceing the power box, if you get a new one and the same thing happens, then the mother board is bad too.
