Phillips 170b monitor not working

Hi, My monitor went black last. If I turn it off and on again it lights up so you can see whats on the screen but then goes black. I've tried it through the USB connection and the same thing happens. I've tried just turning it on without it connected to the computer at all and the same thing happens. Any help would be very much appreciated.

Re: Phillips 170b monitor not working

Most monitors come with a 3 year warranty....if you are within this warranty SEND IT BACK. This problem is usually down to a faulty transceiver. Easy to replace but be sure to disconnect electricity as you can get a fatal shock

hope this helps

Re: Phillips 170b monitor not working

Exactly the same problem here. Phillips 170B Monitor about two years old. Lights up for no more than 2 seconds then goes blank. Switch on/off and exactly the same thing. I suspect than the screen goes really dim rather than switching off because sometimes I can see the screen image very faintly.

Re: Phillips 170b monitor not working

This is most likely a power inverter problem & they are not cheap to exchange/repair. Buying a new monitor is probobly your best bet.

Phillips 170B volume adjustment bar automatically pops up

Usually for the volume bar to just pop up something would have pressed the volume button. It is possible that the volume button has gotten a malfuntion on it and this makes it to pop-up all the time. Try getting underneath the volume button cleaned. But preferably this should be done by an expert.
Hope this solution has been helpful?

Blank Screen

Common problem in monitors are bad caps in the power supply, that is the first place to check, look for bad caps with bulging top/bottom, see example of failed VIEWSONIC monitors due to bad caps here (worst case will be bad lamps):

Turned it on a minute later went black

Good day sir/ma'am hi, if you monitor turns black, here are the more common probable reasons;
  1. Your PC went to standby the screen saver kicks in, just reset your PC then the monitor will power on again.
  2. If not, your PC is not giving you video signal, check to see if another monitor will work, we then know what part is bad, the monitor or the PC.
  3. If the monitor is the culprit, then your monitor's back light or inverter board just went bad. you need to replace it.
There are usually two main circuit board on your monitor, the power supply board and the main board, at this point, you need a professional to do the work.
The process is opening the monitor and locate the LCD screen connection to the main board, to check if the contact is snug. we then test. if still nothing happens, Then we go to the power supply board, to check for connection problem, It would help if there are light signs, like blinking, orange, red, green and the likes? Anyway, if the power supply board is not the faulty one, we substitute the main board with a good one and test to see if it will work, test again. If still no respond, we test a new LCD unit, then test, at this point the monitor is working already, if not, we then replace the power supply board. Huh, very expensive, we already have a new monitor. Reminders, these are to be done by a trained personnel. If you attempt to service this, its expensive, so I suggest you let the service shop do this for you to replace only the faulty part.

sound like the power supply or the monitor bulb is going.
try the monitor on another PC if you can get one, if it works, then you have to find ou the manufature of the video card and get the driver.
