SOURCE: Gateway Flat Screen FPD1830

My Samsung 215TW started flickering like a strobe light when I would turn it on... then after a while, the speed of the flashing would change, and eventually, it would go out. After turning the unit on/off several times, I could get it to stay on, but after a while, it would start to get odd video noise (strange colors appearing on the screen), and then it finally quit.

Once the monitor went dead, I noticed that I could still see the image on the screen, albeit very dark, so I took my desk lamp, and placed it next to the screen, and I could see that the monitor was still active, meaning that there was an actual image on the screen, it was just that the fluorescent lamp that lights the screen was not staying lit.

I got tired of waiting for Samsung's customer service (thats a story all within itself), so I took the monitor apart in search for the problem (I am an electrical engineer and electronics specialist). I saw that there were two circuit boards, one being the power supply board, and the other being the video signal board. Knowing that there was still a video signal present, I focused on the power supply board, as it contains the transformers to ramp the voltage up to the necessary voltage to light the lamps.

I instantly noticed that several of the radial electrolytic capacitors on the board were bulging and looked like they had swollen and then blown. There are 5 caps on my monitor that needed to be replaced: (1x) 47uF/50V, (2x) 820uF/25V, (2x) 330uF/25V.

The 47uF and 820uF caps are on the power supply side of the lamp power circuit, and the 330uF caps feed the control signal into the IC chips that control the ballast of the lamps themselves, one for the upper lamp, the other for the lower lamp.

Once I replaced these units, my monitor started functioning correctly, and I dont have to give Samsung my absolute most favorite monitor ever for a refurb unit that most likely will have 15 dead pixels on it (mine has ZERO).

Go to your Windows display settings and hit the Advance button and try changing the refresh rate on the monitor.

See if that helps.

SOURCE: Samsung 226bw visible flickers just after it is turned on

You may have a faulty inverter or loose power inverter connection. OR
You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

My Dell 1704FPV monitor keeps flickering its brightness from dim to bright? it also has started to flickers through different colours like red and green?? i dont want to buy a new one if i can help it? any...


You will have to open it up and inspect the inside for capacitors with bulging top or seal, or leaking caps first.
Report back what you find so we can guide you further. It can be bad caps, transformers, transistors, bad solder joints, etc.
You can buy replacement board from here (must verufy which version you have): http://www.lcdrepair.us/Invpowersupply.html

Pink screen


Not a motherboard issue. If the screen looks pink it means the backlight tube inside the screen ain't reaching full brightness (the tube has gone bad). If it flickers? Well... remember them good old florescent tubes and what happened when they go bad? Same thing.

You have a bad tube in your screen and ... hence, a defective screen.

I have a monitor that comes on for about 3 seconds then the screen turns black and the light turns orange


Hi cw12345,

I'd would say that the backlights on the screen are broken. One difference though is that the foreground goes pink.

Kind regards,

Your power/inverter board is in need of an overhaul.
The capacitors are failing and possibly a transistor.
If the screen showed any redness or pink whebn it was working, Then there is a slight chance that one or more of the 4 lightbulbs in the screen was going bad and finally went.
If you take it apart and send me a picture, I may be able to tell by looking at it.

Emachine E19T5W Monitor


I have more or less the same problem. Mine only stays on for a second though, but it started out like yours. I took it apart and found that the CCFL bulbs at the top of the screen were so poorly put together that they arced out and in the end melted the end of the back panel bulbs off. The monitor only lasted a year and a half and now it's toast unless I can find new back panal bulbs.
If the screen feels excessivly hot around the corners or if you here a snapping noises (arcing) yours is going the same route as mine. If you want to get rid of yours I'll take it.

Make sure your VGA cable is seated properly. If it is seated OK, it could be the start of a problem with a backlight. When a backlight goes bad, it typically shows up as pink/red color where white should be displayed.

It sounds like the monitor whose writing comes up in pink has a problem with the RGB usually IC driven and all of them sound like they have faulty power supply boards. Will investigate further and give a more detailed answer. Hope this helps for the time being.
