My samstron monitor goes dead after 5 min

I m using a samstron 15" monitor. well it so happens that after running for 4-5 min the monitor goes blank and it remains in this state for next 2-3 hours and after it is turned off for 2-3 hours it works for 5-6 mins again and the same problem occurs. its green led keeps blinking as if it is out of sync but it happens without any tweaking in any display options. the current refresh rate is 60hz at 1024x768 resolution. please provide an early remedy.

Hi,

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.

1995 dodge stratus keeps going dead in driveway. I jump it off and let it run 15 mins to charge battery up. Turn off and crank right up, but the next day it is dead again.


With engine running used a voltmeter and check voltage at battery, you will be checking alternator out put voltage, should have a reading of no less then 13.0 volts, if less bad alternator, the reason it keeps going dead is that the car is using the battery to run it .till the battery has no more power, then you jump it and the battery is charge up again and will run again till it goes dead again.

Have 10 Broken monitors with simalar problems. 1. Dell e153FPB- Video for 2 seconds than screen goes blank. 2. Dell e153FPB- After 20 mins, Display stops working. 3.Dell e1724FPB-Video for 2 Seconds than...


Pleasec look through my albums so you will know what to look for.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My monitor went black, and the power switch just flashes.


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.

After 15 -20 min my monitor goes blank


This could indicate a problem with the graphics card. Take the card out and clean it, then clean the slot that it fits into. (I normally use a small dry paintbrush).

Replace the card, making sure that you push it down gently but firmly and ensure that the plastic clip has gone back correctly that hold the card in place. Rescrew the card back to the casing correctly and reboot.

Hopefully this will resolve your problem. If it does not, to determine whether or not your graphics card is faulty. Change the monitor lead over to the onboard graphics port instead of the agp/pci port and reboot. If the monitor works properly with no problems, then you have a bad graphics card.

I hope this helps.

Monitor displays breifly then goes to blank screen


The green power light indicates that the monitor is receiving from the computer correctly. I suspect it is going into high voltage shutdown. There is a safety circuit that monitors the high voltage and shuts the monitor down if it sees anything amiss. So the monitor comes on and then shuts off. High voltage problems are generally not worth trying to repair. Another example of a worthless safety feature. High voltage failures are not dangerous, and adding the safety circuit just kills the unit when it may have some life left or worse, sometimes it is the shutdown circuit itself which fails!
Hope this helps.

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


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
