It is possible that the fuse has failed and has cut off the power. If so there sould be a failure in the smps- switch mode power supply- which has to power the low tension DC voltages. If you are confidentt open the rear sie and use a multimeter to check for fuse failure , if so check for short in the smps. replace the driver or capacitor or the rectifier. check for any short also on the surge protector. If the DC comes out then we have a serious issue and could be failure of the mother board. you will need to check for microprocessor failure, LCD driver/processor faulty. You will need to be proceeding in this flow chart. Helpful? Good day

Samsung monitor 2232bw plus backlight fade in black backgrounds scenes


Most common failures in these LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply C242 470uF 10V, C241 & C242 1000uF 16V, C261 & C319 680uF 35V failed as indicated in the attached picture, replace them at once.

If the power supply board is working then it is back light problem, first do a flash light test. If you can see the image in the flash light test, follow the steps how to test back light voltages: https://how-to-repair.org/repair/lg-tv-repair-manual-pdf/lg-led-tv-no-backlights-32ln5300-32ln5310-32ln5700-voltage-test-troub/2pyuXwNkBMA.html and follow the steps how to repair back light LEDs: https://www.youtube.com/watch?v=_poWTEihIJU Fix Led Backlights for TV or Monitor Lg Led Tv No Backlights 32ln5300 32ln5310 32ln5700 Voltage Test Troub Lg...

The cpu is running,the motherboard is with green light inside,but the monitor blanck


what king of monitor you have., crt or LCD, does the monitor led indicator has a green light, is there any beep when starting the cpu? how many beeps you have heard when the cpu was starting?.

if there is no led indicator light in you monitor the posibilities of that is the monitor was the problem.
solution: try to check your plug in monitor if it is properly inserted in the power plug or in the vga plug correctly.

if when you power the cpu and your monitor led indicator, turn green and back in the standby mode. listen to the beep sound of cpu if theres any.
solution: try eject the mem card. in the slot and clean the contact with the eraser. and put it back into the slot again after you clean it.

The monitor HPL1940T refuses to on


Is there a LED light on any part of the screen after you power it on?
1) If there is, try replacing the VGA/DVI cable (cable from PC to monitor). If nothing shows up, it means there is a hardware defect and you will need to send it in for warranty or repair.
2) If there is no LED light to begin with, replace the power cable and try it again.
Still no light - repair/replace it. If LED appears - See Number 1)

Power led will not light on


mcdevito75 here, You didn't say whether or not the monitor comes on without the power light lighted. I'm thinking the monitor will not come on along with the led light not comming on, if so, check all connections at the computer back and of course in the wall or surge sockets. If all is well and Monitor still does not come on, bring the monitor to a Staples, Best Buy, they will test the monitor for you.

AOC color monitor model 5En...during power on all led lights blinks then stops blinking without display action. all led lights on no more action observed.


actually if u repair an aoc monitor alone without getting connected to cpu once u switch on the monitor all led's will lit on ( green light ) it will remain on situation until u connect the vga connector to cpu that's the time led's will lit off and only the power led will remain in green condition.some aoc 5en once u power on power led is in green condition and if not connected to cpu it will be in orange condition.hope u get some idea but i am not sure if it will work with ur monitor. but as long as LEDs lit on i think no problem with ur monitor.

Can't find video signal


If screen says "Signal cable not connected " all the time till power led switches to Amber chances are monitor is ok and problem is with graphic card or cpu.Connect to Known working CPU and confirm that monitor is the problem.
If same problem persists on another working cpu after changing signal cable,the interface board in the monitor could be defective.
