Question about Relisys TL565 15" LCD Monitor

Screens works for 5 mins then goes blank!!!!!

After booting up my pc (currently being built using various bits and pieces that i can find) the led on the monitor changes from amber to green & the screen comes on including boot screen etc. PC boots up and will run fine for about 5 minutes, then the screen goes blank. Turning the monitor off, then back on brings the screen back but goes blank almost immediately again. Shining a torch at the screen shows that it is still working. I'm assuming the backlights are working (as they stay lit for the first 5 minutes or so) and that the capacitors(?) running them are overheating or something causing them to cut out. I can't afford to buy another monitor at the moment so want to fix this one myself but need a detailed walkthrough so i know exactly what i'm doing. Any help would be greatly appreciated. Thanks

It could also be that the video card is not compatible with this monitor. After the pc boots up, can you get into windows? Does the monitor always go out at a specific time on boot? Say for example; you boot the pc, windows startup splash screen comes on; screen does a quick flash and goes blank. Then it maybe the BIOS setting for the video. Try changing the IRQ setting. You could also try putting the video card in another slot. Do you have the manual for the motherboard? Ray

No power in the Monitor

Sounds like a fairly drastic fault, possibly in the power supply section. Probably not worth fixing with the cost of new LCD screens, but maybe worth asking at a local repair place.

My VGA signal is active but I have no DVI signal.

You must just have one port to be active.

Let's say you want to use the VGA then it should only be the one plugged-in and vice versa
you can't have both ports to be connected at the same time.

My monitor AOC 912Sw-4 does not turn on. Power button`s led is flashing all the time.At the beginning I waited some minutes and I could use it normally, but right now it is impossible see any image on it.

only choice is to give the monitor for service.
anyway read this, this help you.
is your CPU working properly? if that the case, your monitor is in need of a service.
reasons for why a monitor goes blank?
Reason 1: Wetness
The number one reason why computer monitors go blank is - wetness. Believe it or not, when your computer monitor is exposed to humid air, sometimes water can condense and accumulate in the monitor. This causes the monitor to malfunction and go blank. I've had this happen to my desktop PC at least three times before. What you need to do is to leave the monitor alone for some time and allow the water to evaporate. That usually solves the problem.

Reason 2: Faulty Graphics Card
The next reason why your computer monitor goes black is due to a faulty graphics card. The best way to detect this kind of problem is to connect up a new monitor to your PC, then check if you have a blank screen. If you continue to have a blank screen, then it's likely your video card is faulty.

Reason 3: Faulty RAM
This one is less obvious and less common, but it can happen. You might sometimes get bad RAM modules which prevent your PC from booting up even to the basic BIOS startup screen. To detect this kind of problem is more troublesome, you might need to remove those RAM modules and insert them into another computer.

Reason 4: Loose Connections
Another reason why your monitor goes blank is due to loose connections. The connection from the monitor to the mains is usually a culprit, as is the connection between the monitor and the video card. Check those connections before you declare your computer monitor as faulty.

Reason 5: A Short Circuit In The Motherboard
And the final reason why your computer monitor goes blank? It's possibly because of a short circuit in the motherboard. This is the most undesirable outcome of course, as you might have to replace your entire motherboard. However, it's possible that this can happen - so keep your fingers crossed and hope it doesn't happen to you.

have a nice day.

Blank Screen while Green LED is Blinking.

It's because I accidentally plug the cable to the built-in graphics card port. Now I connected it to the right one and my monitor is working great!

Blank screen


Try replaced with another cables, or used a DVI cable instead. Still the same, then it's your inverter that need to be replaced or repaired. Good lucks!

My samstron monitor goes dead after 5 min


The problem is not yet serious, no parts yet to replace. That is a result of a "cold solder" of the parts inside. Open the case, clean it with a soft brush and look for these cold solders on the circuit board... resolder what you find and check every pin...

see picture, the rings are somewhat the start of disconnected pin from being soldered.


After that test the monitor..... That's it... Fixya me okay...

Monitor flashes image for split second then goes blank but green LED flashes as well

while the monitor is still powered on, but with the LED flashing, unplug the monitor from the PC. press the power button, and the monitor should go off, now plug the pc back into the monitor. Turn the monitor back on and it should work.

Occasionally this will not work for me, but if I repeat it it normally works

Hope this helps - my problem is intermitant so it may be different to what u guys have
