The blue light of the monitor keep flash and no picture appears on the screen

If i turn off the computer or the screen for a long time(normally a night or just a few hours)And turn the machine back on, the light on the monitor will become blue and start flashing and no picture appears on the screen. in order to get it work, i have to turn the pc on and off for so many times (just like doing some sort of warming up) it normally takes about 5-10mins to get the picture shown on the screen. But when i get the screen working, as long as the monitor and the pc is on, nomatter how long i keep it on,or how often i restart the pc. the screen works well. some one please help me.

Re: the blue light of the monitor keep flash and no...

Is it a Princeton monitor? If it's several years old, that's generally caused by capacitors wearing out on the main board. The monitor is hard to take apart, but if you do get it apart, you will see bulging capacitors on the board. These should be replaced with new ones, preferably of a higher voltage rating, and rated at 105 degrees C. These capacitors can be found in small quantities on eBay. Also, if one capacitor looks bad, change all capacitors of the same type. So if you see one that is (say) 1000 uF, 10 volts bulging, replace all those with 1000 uF / 10V, or better, with 1000 uF, 25 volts. If you see 470 uF / 25 volts bulging, replace it with 470 uF, 35 V. The repair is not easy unless you're accustomed to soldering, so you might want to just replace the whole monitor.

Re: the blue light of the monitor keep flash and no...

I have exactly the same problem with my Medion 17" TFT monitor. It is not the video card (tried changing it) or the motherboard. Fitting a different monitor makes the problem go away. The monitor does not display the "No Signal" message when unplugged from the PC either. It must be a fault in the monitor, and as it seems to be a design fault. I suggest you contact Medion and nag for a replacement.

Samsung monitor blue flashing light, black screen


The picture board of your monitor has developed fault. That is why the screen is black.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity, because the fault is not something you can fix in other not to complicate issues..

The repairer will help diagnose and replace the faulty picture board and your monitor is back and better.

Take care.

Screen will not come on. power light keeps going

Make sure all connections are tight at all plugs and monitor at the motherboard if you have integrated graphics. If possible, try another monitor. You could also try re-loading the drivers, but it sounds more like a hardware issue.

Fujitsu-Siemens P15 TFT power/picture problem. it take time to turn on.

It does indeed sounds like the capacitors, I had this problem last year with a Medion monitor where it would turn on and off, when I spoke to Medion they did say that it would need a repair but at the time I wasn't enclined to pay the repair fees for something that may happen again!

Personally I would stick with your plan of getting a new monitor because my view on monitor hardware issues is that if it's happened once it will happen again even if you do repair it resulting in a lot of hassle!
