Green light flashes 8 times


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

Screen won't turn on


You can try to do the monitor self test.
Monitor Self Test:
1. Physically test the monitor autonomously from the computer.2. Switch both the monitor and the computer off, and then disconnect the VGA cable le from the computer.3. Turn the monitor on, pressing the power button for about three seconds. The self-test screen will come up .4. If the image is clear, bright, and shows red, green, and blue, the monitor is working properly. Video issues may be due to the video resolution in the computer, and not the monitor.5. If the image is not apparent and intense or the colors are not accurate, then the trouble is with the monitor or some of the (OSD) settings. In this case, test your particular monitor's information for OSD.
It is always important to check the color of your power light for so you can distinguish if the monitor is defective. Getting red lights on the the power panel states that the power section of the monitor is faulty.

When i switch my ps3 on it switches off and lashes green and orange light


There is no orange light built into the PS3 system, you may be mistaken orange for red. If it's bright it can be hard to tell the exact color.

Does the lights blink? If so, you have the infamous YLOD, aka. Yellow Light of Death. This is the number 1 cause of pS3's dying. It is an overheating issue linked to your CPU and GPU (the processor chips) You will need to find a local PS3 repair shop who can repair this. Do not try to attempt repairs seen on the internet yourself. You could make things much worse and render the unit totally unresponsive. The repair process takes about 3 hours.

It can be fixed.

IS THERE A DISC STUCK INSIDE?



If you have a unit that is not backwards compatible, any non 60g or 80g then you

can retrieve your disc.



Power off the unit using the toggle switch on the back. Hold down the 'eject'

button and turn the toggle switch back from off to on. This will run a fan test

and eject your disc. Remember, this will only work on the 20, 40g models. Not the

backwards compatible units with the 4 usb port holes and the memory card slots.

Dell Inspiron Vostro 530s won't boot.


Hi,

I work for Dell, If the power button led light is flashing amber or amber (the Power supply is faulty) The Yellow light you saw inside the motherboard is the "Flea Light" (that is one way you could check if there is still power on the motherboard). Since the motherboard was replaced there are a few more things to check:

1. Video card (integrated or expansion)
2. Monitor (Make sure it displays self test feature when the cables are removed)
3. Monitor Cables (VGA / DVi)
4. Power Cable on the Monitor (try a different cable)
5. Power Supply (you already checked, but i suspect this is causing the problem)

Hope this helps.

Won't switch on


What brand TV is this? Sounds like the power board may be out. You could check for power at the power board with a Multimeter. You need to have power run to the TV but TV not powered on. Board usually has a led green or red light to indicate power to the board. Sometimes this light can be seen without taking the cover off, sometimes you may have to remove cover to see power board and definitely to test with multimeter. Hope this helps. J
