Question about Samsung SyncMaster 204B 20.1" LCD Monitor

Gateway Flat Screen FPD1830

When the monitor is turned on after being off for a while, the screen is starts to come on, then flickers to black. Leaving the on switch "on" does not seen to make any difference, but after turning the switch on & off for a random number of times (the screen flickers on & off each time), the screen finally appears to "catch" the message, and flickers bright & dim a few times, to finally come to a fully bright screen. At this point, there is no more flickering until the monitor is turned off for a while.

The "on" button light is "on" when the screen flickers black. When the screen finally does work, there is some "crackling" noise coming from the back of the monitor.

There was been no new hardware introduced within the last year. This flickering started a few weeks ago.

I get the strong feeling that something is warming up during this flickering period and may soon no longer work.

Any ideas?

Re: Gateway Flat Screen FPD1830

I can not solve the problem, but I can add to it..My fpd1830 screen stays black with the power button green and flashing. I replaced the inverter board with a new one and it still does the same thing!!!!!
The inverter board is not always the solution to the black screen!!!!!!!!!

Re: 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).

Re: Gateway Flat Screen FPD1830

I have the same problem with my Gateway LCD Monitor. It takes a few mintues for it to come on. This started a month or two ago and is getting worse by the day. I've been unhappy with the Gatewary computer and monitor since the day I bought it and it has been one problem after another. I will never buy another Gateway.

Re: Gateway Flat Screen FPD1830

I have the FPD1830 monitor and experienced the problem of not having the monitor operating on start up. I have used a hair drier to heat the back of the monitor as I turn it on and off repeatedly. This works but is steadily getting harder to get it to operate. I want to replace this monitor.

What is a better LCD replacement monitor (brand, model) than the one that I have?

Re: Gateway Flat Screen FPD1830

The problem is most likely coming from the CCFD inverter board (the power supply to the lights behind the screen). If the screen is "flashing", then there is a problem in the CCFD area of the monitor. If the problem is "flickering" (screen jumps around or is not stable), more than likely you have a LCD board issue. If either of these issues are occuring, you have two choices: Repair the monitor or replace it, in either case it could be expensive.

Re: Gateway Flat Screen FPD1830

Well, this problem is going to only get worse. You can probably send it back to the manufacturer if you still have a warantee, but if you can't just buy a new monitor.

Just received a used FPD1830 monitor, connected to an aspire1 netbook, the power light comes on green and then goes directly to orange, the screen stays black.

Try it desk top PC first, this model is know to have bad caps in the backligts inverter board.
So check the caps and the fuse in the inverter board as shown here:

Basic LCD monitor and TV troubleshooting guide:
Failed TV and Monitors:

Learn about bad caps:

Capacitors kit: he can make you a set of caps for you.

Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
Please leave rating if it helps.

Lcd monito fpd1830 is not showing the display

If the indicator light is on but black screen, then replace all fiur caps (100uF 25vdc) with on single cap form DIGIKEY PANASONIC FM or FC, it muat be LOW ESR type! (this is very common problem, I fixed about 30 of these already)
See my pictures here:

The caps look OK but have high ESR as shown in my albums.

It can be bad caps in the power supply, bad inverter circuits (check the green color fuse (F1, 4A 125V) close to the heatsink and a trim pot), bad inverter transformers, bad lamps.
You open it up using flat blade screw driver starting along the bottom edge of the case. Post back what you see insdie so we can guide you further.

I've had my monitor for a year now and last night my screen went black. It flickered a few time before it completely turned blank. If you look closely you can see my desktop on the screen but it is almost...

pmeyers843, If in fact your LCD is only a year old, I would first contact Gateway to see if they could do some sort of swap-out with your unit whoose switch-mode-power-supply and/ or cold-cathode-fluorescent-tube power supply (called an inverter circuit) has failed prematurely. Yes, this does happen to a lot of monitors of all brands not just Gateway! But it is way more likely to happen after 36-48 months into the life of well used lcd monitors that have lots of "ON" hours use! I also suggest you pay a visit to youtube and view some videos of LCD repair to show what are some of the components that typically cause a failure similar to your's. Get back to me if you need more info. I hope that this helps to solve your BLACK SCREEN problem. I'mlouie12fix on fixya or
Good luck. Bye for now.

Gateway FPD1830 Monitor Flickers then goes black


It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. Look in our monitor repair section for step by step repair guide for this model. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.
