SOURCE: Monitor goes blank

Sounds like the back light inverter board is bad. It's a very common problem. LCD's use four small cold compact fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it) The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display. If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad. The inverter board and CCFL's are replaceable. Good Luck, El Duderino

SOURCE: problem in monitor

you need to either buy a new inverter board, or if you are competant with soldering onto boards, you need to replace the c5707 transisters at points q740, q739, q760 and q759 on the larger board. best place really for the replacement c5707s is ebay

SOURCE: Dell E153FPd Power stays on but video goes off after 2 seconds.

3 ideas here. bad connections on the coils inside. the inverter board has gone bad, or bad capacitors on the power board or inverter board. all of witch should be serviced by a qualified service center.

Hi, i have viewsonic 1940w. When i turn it on it makes buzzing sound and after 5-30 seconds it goes in stand by mode(orange light). Sometimes screen flickers to. If you turn off monitor and on again you...


I fixed this same Viewsonic problem by replacing the electrolytic caps on the power board and re-soldering the power transformer joints. The noise is coming from the transformer, if you torque it the noise stops. Cold solder joints must have been the cause (large posts did not heat up enough during construction). The bad joints might have caused a cap to overheat too, not sure but one was swollen and leaking and after replacing them the squealing was stronger and allowed a longer running time to locate the cold joint.

Monitor flickers and goes blank after 5 seconds and keep repeating this very often.


Hello,

If you turn the monitor off then about 1020 sec turn it back on and have a picture for five sec again it sound like the power supply in the monitor. but if that did not solve the problem, the picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault and will need to be replace.

I advice you replace the picture board on the screen of your monitor to solve the problem of the blank screen.

Take care.

Flickering screen


Hello,

The flickering problem you have is caused by a failing power supply. There are parts called capacitors that are failing and causing the power supply board to put out pulsing voltages until it can stabilize. We have a repair guide posted on our web site at: http://www.ccl-la.com/blog/index.php/samsung-214t-repair/ If you can soldethen you should be able to do the repair yourself. If you don't want to do the repair we offer a repair service for this unit. You can get details for that service here: http://www.ccl-la.com/blog/index.php/service-request-form/

Problem with monitor


Hi.
Are you able to see a slight image on it at dusk and maybe with the help of a flashlight. since your blue light stays on the video board, may be okay.
It sounds like you have bad capacitors on your powerboard or possibly a burned out transistor on the inverter.

Only way to really tell is to open it up.
If you unplug the screen to video board ribbon, you may notice a different effect in the screen lighting.
There is a chance one of your bulbs is creating a problem
Should the screen happen to light up all white, then your power board and inverter are okay and the problem may be in the video board.
If it looks pinkish or dark or flickers then the bulbs or a bulb may be the issue.
If it flashes on then goes off, it's in the power or inverter board.

Monitor displays breifly then goes to blank screen


The power -inverter board probably needs an overhaul.
I redo many of these.
If the screen was pinkish or flickering before it finally got to this point, it is possible that a bulb has gone bad.

Monitor image flashes off and on


Sounds like you've done all the trouble shooting. If you just need that extra nudge, I would agree... it sounds like you'll be needing to shop for a new monitor.

Screen displays fine for a second, then goes blank


Dor, BenQ has a 3yr warranty on their monitors. I would contact their tech support and receive an RMA to return it for repair. It will cost you shipping out there but they will ship it back. I has a BenQ FP731 myself and it blew a capacitor inside that allowed the screen to stay on. Fixed it and had it back in 5-7 days. Good luck.
