Monitor model 1702FP wont start. lights keep cycling


Hello,

The flashing power and signal lights are caused by 4 bad capacitors on the main driver board. Here is a link to information showing where they are and how to replace them.

Green light flickering & Sunset red screen display.


You've got components that have gone bad, probably from age and the normal heat inside a CRT monitor case.

I hate to say it, but it's really not worth fixing. You can usually find a used but working 17" monitor for under 20 bucks.

Monitor light blinking


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 occurr 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 statebecause 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.

No display, clipping sound appear


The clipping sound is the internal safety switch that keep shutting down the monitor.
It means there is an internal problem on the main board (overvoltage, bad component , short).
Try unplugging power cord and leaving it unplugged two or three hours, this will reset ICs by draining power completely from circuits, it is called hard reset, it rarely works.
CRT monitors waste up to 15 times more energy than TFT screen, if your CRT starts giving troubles, then it is a good time for upgrading it to a new TFT.

Problem with 17" ViewSonic Monitor


The same problem w/ my viewsonic E70 17" monitor.The viewmeter or viewmatch color on screen do not appear when power ON, although the green led power is ON.

But if you rest your monitor for about 10 hrs or more the viewmeter will appear when you power ON the monitor.

You can now start your CPU.

Remember : No viewmeter screen on monitor when power ON, means no supply coming out the picture tube or high voltage.

But if there is Viewmeter on screen , this normal and OK>

Power light flashes with no display


That usually means that the connection between the PC and the monitor has been interupted- check that the cable (probably has blue ends) between the two is firmly connected, and power it back up. If that doesn't work, you have one of three problems; a broken VGA cable, a broken monitor, or a broken video card. Finding out which- you'll actually need someone tech-savvy there to help you figure that out. Try plugging the monitor into a different computer. If that fails, use a different VGA cable (cables are pretty cheap at monoprice.com), and if that fails, it's your video card.
