Re: No Green

Check the crt board and follow the green signal path, could have a shorted transistor or a resistor out of tolerance on that line, check all the components on that line

There no diplay eccept lots of blue, red, green lines on the monitor, please help

Try another monitor if it works the way it should then it's the other monitor. If the result is the same reboot the computer in safe mode by tapping the f-8 key when you see fhe first splash screen choose safe mode. If it still messed up then you have a graphics problem. Take the computer in and have it tested.

I have a Samsung LED computer monitor (model S23A300B). The monitor connects to my Macbook air. The Samsung monitor recently stopped showing the picture on my laptop. Instead, red, green, blue and white...

Try the plugging the setup into a different monitor to eliminate the lead however it sounds like the monitors died. With cost of screens even if you can get hold of one you'll be better off getting a new monmitor.

Monitor will not stay on

Generally Monitors have a single light in fron pannel, with dual mode colors as Green and Orange.

Green: Everything is OK .
Orange: Everything is OK, except it is not getting
any signals from computer or other source.

Try with any other monitor with your CPU, it may happen that CPU actually not providing any signal to Monitor. Try checking the "NUM LOCK" button on and off, whether it makes the light on keyboard to flash on or off.
If NUM LOCK is woking OK, there is surely some problme with your monitor and you need to get is checked physically with an engineer.

My monitor will not come on, the on/off light flashes occasionally and the monitor gives over a very brief light

make sure that your cpu is working. if the cpu is dead, there will be no display in the monitor. If the monitor light is flashing as you said, it could be the CPU not sending video signal to the monitor. also check if the cpu beeps when you start your computer. if not, check your cpu. try to re-seat your RAM modules. this will solve most of these types of problems

The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.
