My B350 monitor stays on for about a minute or two then goes black/blank. It also flickers during that minute or so it is on. Only 6 mos. old!

This model monitor definitely has a flickering problem as reported by many people and it is very annoying. Mine developed in the 1st 2 weeks and I returned it for a refund. Not sure what the Samsung warranty is but I would try to return or exchange it. At minimum send for repair.

Return it if you still can. That's most of buyers do, including myself. Don't exchange a new one since the problem exists in almost all B350 monitors (as far as I know, every one has exactly same problem. Some shows early, others later). Besides, monitor neck (stand) is made of plastic. 27inch is too heavy for plastic. I returned my B350 and got a 24inch ASUS and 100% of its stand is made of metal. Also, take it as a lesson. NO MORE SAMSUNG! Plasticky electronic products never last.

We have the same problem with our TV. The screen is normally very dim, then gets very bight. We've never had the screen go black. We have also noticed the same phenomenon that J. Wu mentioned about the lamp.Have either of you solved this problem? Were you able to exchange it?

Very similar issue: flickering problem on this 55 inch. This all began about 24 months after purchase. Does anyone have a solution other than calling a service technician and paying for the repair yourself?

Every time I'd turn the screen on it would be perfect, then after about 5 seconds the entire screen would become a dead pixel. The PCB going bad is apparently a common issue with these monitors. I told the seller about the issue and they paid to have it shipped back to them, no hassle. Got another one and it's perfect, no dead pixels.

Mine stopped working as well. It lasted for about 6 months. Sometimes it decides to turn on. When it does, after some time, it flickers on and off and then shuts off completely.I have a second one, that's just as old, that is working perfectly fine.... for now.

I have an acer al2216wbd running as a secondary monitor on my Mac Powerbook running OSX 10.4. When it works, it works great, but... there is this one issue where the monitor refuses to work after the computer has been put to sleep. It blinks on for less than a second, then goes black. The only way to get it back is to plug the monitor into another computer, have it autoconfig, then plug it back into my powerbook. To avoid this issue, I have to turn off the monitor before the computer's display is put to sleep. I believe it has something to do with drivers, but there's little info out there.Update: I returned it, turns out I had a defective monitor. Replaced monitor doesn't have the aforementioned issues.

I haven't had any problems with mine, but I did have a similar problem with another model and this is how it started before the whole screen went dark. I had a technician come by. He said it was the mother board and that he would fix it but he couldn't guarantee it wouldn't happen again. He said that it's best to replace the mother board, and if you have to do that you might as well buy another tv. I took a chance and he fixed the problem temporarily, then it died, so I threw it away and bought this LG. I've had it since July 2013 and it's worked fine. Mine is the same model in a 50-inch. I did buy the 5 year warranty just in case since it's new technology. With these smart tvs it's best to get the warranty because you never know. If it's still under warranty, you should return it and have them replace it before your warranty expires because once the mother board gives out it's too expensive to fix and you're better off buying another tv.

Return it. I'm not kidding. My first monitor had color shift , the next worked for a year and then started flickering. That was followed by 4 refurbish units, each one with its own set of problems right out of the box. Finally talked the local rep into getting them to send me a brand new unit. Well, that was last February. The monitor has since developed a flickering problem. So now I'm waiting on another refurbished unit that will probably be defective in some way. HP has horrid quality control, and they're repackaging broken monitors and sending them out. It comes with a DVI cable. Return it. I'm not kidding.

There is a timeout setting in the device so that after a certain time of being on, the screen will blank out. I think I have it currently set at 3 minutes so after it turns on, you can see the display for 3 minutes, after which, the screen will just be black for the remainder of the time that it is on.

No...What ever your output display card is...is converted to HDMI. If you buy it let me know if stays on. Mine stops working when it is on for about an hour.

No. I pulled mine apart because of the same issue and found it was the back lighting (shine a flashlight when it is on and you will see your screen still works, just no backlight). The lower CCFL wires for mine had a bunch of unidentifiable crystal like corrosion which might be due to bad SIC insulation but my CCFLs worked fine. I cleaned the corrosion and tested good. Prior to that I swapped out all of my electrolytic capacitors on the supply board. Still nothing. Considering getting a new one to match my good one or buy two new monitors and move on.....not sure yet.

I have also had intermittent connection on the Mini Display Port connector. I would get a blinking display or lines in the display. Make sure it is well seated, then it seems to work better. I am not sure if it is only this cable, or inherent in the Mini Display Port connection.

Ivan had a legitimate question Cliff with a sarcastic answer from you. My monitor has the same problem and is worthless at this point. If we figure it out I will fairly rate this product. Our security system is a high test system and not from the big box stores.

Mine did the same thing, after about 20-30 hours of use it stopped. The bulb will also occasionally flicker, though this didn't begin until it reached about 500 hours. For the money, I had no real complaints, but if you can afford it, I would go for the factory original...... most of these aftermarket bulbs do odd things, and rarely do they work perfectly out the box.

I would no rush to replace the power adapter just yet. If you can-try a similar power adapter with the same power and plug. IF you have one you can try it and see if the monitor fires up. If you have a compatible battery you can also try that. Normally the power adapter is OK. It is probably the monitor itself. I have never found a defective power adapter in all of my 52 years. I have seen circuit boards that are faulty on new products. If all else fails-ask the gift giver to exchange it for you.
