This type of issue is usually trace to the power supply board. When the capacitors start to fail you get the flickering and dim picture until they can get fully charged up and then its ok until you turn the unit off and they discharge, then it starts all over again. Here is a link to a repair guide with disassembly instructions and what to look for and replace to get the unit back running again.

This sounds like a power supply problem, how old is the monitor? If it is not new in the last year and is used regularly it sonds like a faulty capacitor in the power supply. If you are aware of the precautions necessary when handling capacitors and a moderatly competent solderer then you can replace then yourself - a complete set of capacitors usually costs around £3 or $5

I have an ASUS model X83V and my screen has been flickering (not in brightness, but actually going fuzzy and "jumping"). The flicker can take upwards of 1 hour or more before it goes away, but usually...


my son has this same machine and after a year of almost daily use it developed this same flicker you describe, about every 4 secs, then it got much worse, almost like an old tv rolling. i took it all apart and inspected it all. didn't see anything really troubling.

yesterday it worked fine all day while i installed a bunch of updates for another problem. i left it on all night doing some other things. this morn when i got up it was still ok. then after a while it started in again, every 4 secs.

so i've been troubleshooting the damn thing all evening and have come to the conclusion its from over heating, probably cause of the crappy heat sink connection. i noticed if i take it outside in 40 degree weather and leave it a couple mins on the hood of my truck, it goes away. bring it back in and after 5 mins it comes back. take it back out and its fine again in a few mins. also, yesterday my house as much cooler. my fire was out and it was in the upper 60's in here, today as soon as it got to 76 in here, and it was above that all day, it started acting up

so i think my next step will be to try and make a better union between the chips and the heat sink itself. you should try a test with yours. start it up, make sure its flickering, put it in a cold space for a few mins. just be caustious of condensation.

Dim monitar with flickering screen


Hello,

The problem can be caused by 1 of 2 things either your power supply is going out or the backlight bulbs are going out. The most likely cause is the power supply. If you are willing to do a little soldering you should be able to do the repair. If you go to our web site at: www.ccl-la.com/badcaps.htm We have a section on monitor repair. Look under the Samsung 930B it is the same as your monitor.
If you don't want to do it yourself we do offer a repair service, email me if you are in need of that.

I hope this helps.

Sumsung 930b goes dim,and flickers after about 3 min.


This sounds like the inverter has gone bad. If the bulb were bad only, you would see a faint image on the screen with a flashlight.

The problem is on this monitor, it will probably cost about $100 or so to take it to a shop to get it fixed, and that is nearing the cost of a new monitor.

If you are a little bit handy, and can disassemble the monitor, you can replace the inverter. The hardest thing about this, is getting the monitor faceplate open. Just use something firm and softer, such as a nylon spudger (this is something you can find online) or you can carefully use a thin scredriver. You just have to be careful, those cases are really tight.

Here is a good guide for general ideas on how it is done.

MacBook Screen Problem


Hi there
If I understand you correctly from start up the screen is dim but does brighten up after time? But now after start up you are getting a flicker how ever a restart solves this.

On the dimming issue. Check your energy saving settings and brightness key is working OK.

The flickering is a bit of a concern.

Just a couple of questions.
Are there any dead spots on the screen? Areas where there are no pixels.
When you tilt the screen forward and backward, does this effect the brightness or flickering?

Flickers on cold startup after 5 min then goes away in 2-3 min.


I had same problem. Tech's said the power was noisy. I cleaned up the power but the TV still did exactly as you describe. Problem will progressively get worse with longer bouts of flickering. I was under warrenty and sent the TV back. After 3 months I am still waiting for a repalcement.
