I have a Gateway FPD1830 LCD monitor that is just over 2 years old. The problems started about a month ago. For a few seconds after I turned the monitor on, the screen would flicker. Then everything would be fine.

About a week ago, I turn the monitor on, it flickered and then went black. The green light remains on showing the monitor is getting power. I can turn the power off and back on and the same thing happens: it flickers for about two seconds, then goes black.

Needless to say, it is very frustrating to try to use my computer like this.

From my limited (and newly acquired) understandings of how LCD monitors can go bad, it is either a backlight problem or inverter type problem. I am willing to crack it open and replace parts, but I'd rather not waste money trying to fix something that isn't the problem.

I have not tried anything other than leaving the monitor off for a while (which has no effect). I am convinced this is a hardware problem. I've checked all the cables and everything seems fine. What should I do: replace a backlight, replace an inverter, or scrap the whole thing and buy something new?

Borrow a good vid card and monitor to test your system with. If another monitor works, then it's probably your monitor. If the other monitor doesn't work, then replace the vid card with the borrowed one to see if that's it.

17" LCD's can be had for $200 almost anywhere. I've seen sales as low as $100.

I have no clue about inverters. If you turn it upside down does it work? (just kidding Smile
Good luck!

Have you confirmed that your graphics card is operating properly? I would check that before considering messing with the monitor itself. Is there an old monitor you could hook up to test whether the card is sending a good signal to the display? It is more likely that a 2-year old graphics card is malfunctioning than a 2-year old monitor.

GregofVT - No sweat! I was locked in the page and couldn't get out - so I couldn't tell what was going on.

Reminds me of what an old boss used to tell me - "Some is good, but more is better" Smile

Unfortunately, I do not have another monitor at this time... I will try to get ahold of one and check it out.

It just seems very odd to me that it could be the graphics card. The weird behavior seems to depend on when I turn the monitor on, and has nothing to do with what the rest of the computer is doing. The monitor does not show a message that it is going into power-saving mode (which it would do if it stopped getting a signal). So the only way it could be the graphics card is if it only went bad as the monitor was turned on but there was still a continuous signal. Could that happen?


Thanks for the help though

The graphics card could have a break or a short that could result in a poor/bad signal being sent to your monitor. The extra load on it (in sending stuff to the monitor) could precipitate a malfunction of the card. Since the signal is being sent the monitor thinks it's working and won't give the "No Signal" message.

Hello,

Does the monitor cable detach from the LCD display? If so, have you tried swapping it with a different one?

Regards,

I just tried hooking this monitor to a completely different computer. Unfortunately, the exact same problem still occurs.

I do not have another cable with me.

However, I did notice that even while the monitor was unplugged from either computer, the "No Signal" message flickered and disappeared.


Thank you for all the suggestions so far, but are there any other ideas or suggestions? Please help!

Unfortunately if it did the same thing on another machine than it's the monitor and not the vid card.
You could try it on a third machine just to be sure.

Final shot here.....Try wiggling each end of the cable while it's plugged in and acting up. Does the wiggling change anything? If so, then it's possibly the cable.

I have the exact story like yours with mt monitorn FPD1830... word per word. Over 2 years, the flickering...everything.

It's better to buy a new one or just keep it turned on - it's like a neon light with a bad "starter". The "starter" it's the equivalent to the inverter.

I can't believe that the warranty expired one month ago!

Gateway "chat help" wanted me to buy another one instead of repairing it... they know something's going on with this monitor.

Not sure how to post this, but it appears that something is not right with these FPD1830 monitors. I too just began experiencing the same issues with my 2 year old monitor over the last two months and last week, it died. That is, it flicks on, then goes dark, when turning it on and off ...or using the Source Set switch to go from analog to digital. This monitor has both an Analog and Digital input, and neither feed works from the video card. I ran an analog line to the monitor only to get the same results. I tried this with a laptop as well as with my desktop...same flickering results".

Quite frustrating. I did hook up an old 17" CRT thru the analog line and I'm back in operation....after spending some 5 hours trying all sorts of ways to get flat panel to work, to no avail.

If anyone comes up with a fix that involves "a hard whack with a rubber mallet" or something cheaper than a $99 inverter...please pass this along.
Thx,
Mark

Flat panel monitors are nothing new. They've been used in laptop computers for years. I've replaced many inverters over the years. And, a few broken panels as well.

Did I hear, "Gateway"?
They must have very low specs on the monitors they buy. Some years ago they were buying 17" CRT monitors from Sony,,,but they had a serious flaw and readily failed.
Even the MAG monitors they bought had problems.

I worked closely with a service center in Longwood, Fl. that rebuilt those monitors and sold them at very discounted prices. I still use one of the rebuilt Sony's for a repair bench monitor.

You could probably replace one part, then another part and still maybe not get your monitor working properly. The parts you would get are probably just like the ones that failed and will fail themselves in like time. If one part of a monitor is of poor quality, then the entire monitor is suspect.

My suggestion would be to take it to a certified service center, or just replace it with a new, brand name monitor. Take a good look at the warranty before you buy.

Good Luck and God Bless,

I also have a FPD 1830 that has given me trouble with in the first 8 months. I had it repaired under warrenty backlight issue. Returned it to me with in a week good turn around time. with in 4 months the monitor died on me again. One day it was working fine. I got up the next day and a I had nothing but a blank screen. It had just passed the warrenty but the regional manager okayed the repair of the unit which was realy just replace with a referbished unit, I know that cause they told me that as they were handing it back over the counter to me. I was glad then that they did take care of it but 9 months later I actually witnessed the flickering screen till it no longer showed any picture. I hooked up my old faithful CRT up the computer so I could use it to get on line and go onto gateways customer service chat line. I was offered to buy three different video monitors for a replacement and also a repair of $350 for the monitor that I have now. Clearly they do not want to service this model. I had asked the service rep. twice if there was a history with this model, no response to that question directly, but he did have a monitor that he could sell me for 299.99 with free shipping. I asked him how do I know that that monitor wasn't going to give me the same problems as the one I have now. He I could tell just wanted to get me off the chat and move on. Maybe cause it an hour and half into the chat and I still didn't want to buy his new monitor. Needless to say I am frustrated that I spent probably $650 dollars on the monitor and it is a little over two years old as indicated by the manufacture date on the back of the unit and is no longer working. Gateway was not interested in correcting the problem. I would repair the monitor myself if I knew where to get the parts and it probably is the inverter as others are stating.
Any one have any ideas on the repair?

Sounds like were all in the FPD1830 monitor regret club.
Sad

Thanks

Hello,I am new to this post. I "googled" monitor flickers and found this site.
Glad I did, even though my reply is a couple months behind.

I have a 3 year old Gateway FPD 1810 lcd monitor. It has been flickering about a year now. As your post have said;Gateway was of no help.
Finally last week I replaced my video card. I was doing fine until a day later when the dang thing started to flicker again.

So I got my old crt tube and pluged it into the crt port while my lcd tube remained pluged into the dvi port on the video card.

Somehow I was able to clone both to work at the same time.
What ever I "moused" in one screen worked at the same time on the other screen.

Then after an hour or so lo and behold the crt is still working just fine and the Gateway lcd FLICKERS like crazy.

Anyone know of a good replacement lcd with a valid track record.

Thnx

Hello,

I have used NEC, SONY and Viewsonic LCD displays and been very happy with them.

I have the same problem. My monitor is dead. I have a gateway p.c and have had more than my share of problems. Now they are refusing to send me a new monitor even though I am under warranty. They want a credit card number because they don't trust me to send back the monitor. I have sent all my defects back in a timely manner. They say it is a new rule. Even though I understand the rule I don't think that any Gateway product is worth a dime.

STAY AWAY FROM GATEWAY!
