Question Dear Philip
I hope you may be able to help. I have had a Dell Dimension 4700 Desktop (with a Dell E153FP 15" flat panel monitor and an inbuilt ATI Radeon X300SE video card) for 18 months. The other day the screen suddenly went blank and the monitor "on" button began to blink green and amber. About 5 minutes later the monitor suddenly started working again (displaying the web page i had been reading) but then a minute or two later the screen flickered, went blank and the blinking light returned. I have not been able to re-establish any sort of picture despite turning off and rebooting. The computer itself seems ok, the diagnostic lights are all green and all the connections / cables seem intact. The monitor light continues to blink when attached to the power supply (and for a short period after the power cable is pulled out) even when disconnected from the computer but there is no picture on the screen. I do not have access to any other monitors to test the system and I am reluctant to invest in a new monitor if the problem may be related to the video card or elsewhere.
Thank you
Sam
Answer Sam;
From your description, this sounds like a failure in the internal power supply of the monitor. You may consider having the unit repaired, but the cost is likely to be prohibative, around $95.00. I would recommend that you upgrade to a newer and possably larger display, and you should be able to do so for less than $200.00. Again, from the description, the monitor is to blame. I would recommend taking your display to some other computer, even a laptop if it has the correct connector, and confirming that the issue follows the monitor. Abscent that I am atleast 90% sure that the issue is with the monitor its self, not the computer.
