SOURCE: Monitor black screen with blinking amber/green light

You need to reset the display. The display is in a safe mode. Resetting the display is a simple procedure and Planar has the instructions on their website in their online customer support section.

SOURCE: Dell dimension 2400 blinking amber light

1. Remove All External Devices
2. Check the Computer's Power LED
3. If the power LED has not changed unplug the Power Cable From the Computer Disconnect All Hard Drive Power and Data Cables and power on the computer. If still no go.
4. Remove All PCI, PCI-E, and AGP Expansion Cards .
5. Remove All Memory From the Computer
6. Reseat the ATX and 12-Volt Connections . The ATX connector will be a 4 pin square connector connecting to the motherboard from the power supply and the 12-Volt Connection would be the biggest connector with a lot of colored wires.
7. If still no go.
8. Disconnect the Power Connection to the Chassis Fan
9. If the light still flashes then it could be a power supply or motherboard failure. Try a good know power supply first and if that does not fix the problem it is the motherboard. Also check the back of the tower for 4 lights lables ABCD or 1234.
Rate if useful.

SOURCE: lg tv very slow to turn on

slow turn on's are usually a power supply problem, capacitors in particular. Are you comfortable with opening up the set? If it is under any kind of warranty don't open it, take it back to the place you purchased it.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

LG symbol on screen flashes on once and red light blinks twice slowly, no sound either. What does 2 blinks indicate ? please advise


Corrupted firmware. A firmware update is necessary. 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/

No video no picture, caps look okay, what could be wrong or how to tshoot to determine which PCB is bad etc


Does the screen flash on briefly then go black when first switched on? See my posts in march for my answer to this fault.I traced the same fault on my own tv down to a faulty led in the backlight strip. Also my tv did the same thing,standby light flashed twice and then went out.Hope this helps

Computer will not turn on


  • Blinking Amber/yellow: Initial state of LED at power up.
    Indicates system has power, but the POWER_GOOD signal is not yet active.
    If the hard drive LED is off, it is probable that the power supply needs to be replaced.
    If the hard drive LED is on, it is probable that an onboard regulator or VRM has failed.

Powers On if I plug it in, and power supply fan runs...


Think of blinking amber as the initial state of the LED. As long as the system is receiving power from a power source and can pass that power through the system board to the LED on the Control Panel it should, at least, blink amber. As a result, a blinking amber Power Button LED is a reliable indicator that the system is receiving power from a power source. This, in turn, tells us that the source and power cord are likely to be functional. The Blinking Amber LED also tells us that the power supply to system board connection is good as well as the connections between the system board, I/O Panel and Control Panel. Depending on the components installed and the condition of those components, the LED may progress past blinking amber and move to solid amber. If the LED does not progress past blinking amber it indicates that the system is not able to properly distribute power to the system components. This is discussed in the next section of the interaction.


It does not indicate that the power supply is bad. It simply indicates that, for whatever reason, one of the power supply 'rails' is not operating within its specified range or, simply, that there is a short somewhere in the system.
The LED state could be the result of a misconfigured or incorrectly installed system component. A bad drive, for example, may be shorting out one of the rails. Incorrectly installed memory can cause a blinking amber front panel power button LED.

Computer Won't Power Up


If the blinking amber LED is on the computer itself and not the monitor, this is most likely a power supply issue. First thing to try would be replace the power supply. If the blinking led is on the monitor, it probably has bad capacitors and needs to be replaced. (or repaired)
