Question about NEC LCD1712 17" Flat Panel LCD Monitor

1 Answer

LCD Monitor picture cutting out occasionally.

I run two monitors, a CRT and this LCD which is the problem. This problem just started today, after about 30 minutes of the monitor being turned on the LCD screen will go blank. The power light on the LCD remains lit, and I can restore the picture to my LCD by power cycling it, but after a short (5-10min) amount of time the picture will go out again. Is there anything I can do to fix this? I've already tired cleaning out the dust by blowing compressed air into the vents as I feel it might be an overheating problem but this did not solve my problem.

Re: LCD Monitor picture cutting out occasionally.

Your CCFLs might be going bad. CCFL stands for Cold cathode fluorescent lamps. These are the lamps that provide backlight for the LCD Monitor. These lamps do not last forever, and are a very common part to go bad. The circuit that provides the power for the CCFL is called the inverter, it might be going bad, but I still think it is the CCFL. Only trained techs should try and replace a CCFL or fix an Inverter. CCFLs do contain mercury, but only small amounts.

Since the monitor works for a few minutes and then goes dark, this tells me you have a problem with the backlight function. I have seen this several times, and I do work on LCD monitors professionally.

My advice, get a new LCD monitor and sell your bad one on ebay.

17" flatron crt monitor only green led blinking and tick tick sound .No display

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Where is degausses key on my monitor"

LCD monitors don't have degauss buttons. Degaussing was needed with CRT monitors because a magnetic charge would build up on the screen and need to be reset occasionally, though in later CRTs this was done automatically whenever you turned the monitor on.

When i turn my monitor on it shows no picture and it makes a sound like it is running the electricty went out and when it came back on thats when the trouble started thank you

It's time to spend $100 to buy a brand-new 19-inch LCD monitor,
or $200 to buy a brand-new 22-inch LCD monitor,
rather than paying a TV/CRT technician $50 to $75 per hour to try to fix the "antique" monitor.

About how old is a 17" compaq 7600 monitor?-any reliability issues with this one?

This monitor is 2-3 years old.

There are not any real reliability issues, but it is a crt monitor, meaning that it uses more power then todays lcd monitors.

Its worth about $50 used.

My laptop is on and plugged to the monitor, but the monitor says no signal

You have to switch your laptop to a different display mode. Usually it's done by pressing Fn key and F8 - look for a description near this key showing rectangle / rounded rectangle, or text "CRT / LCD".
Usually there are 3 modes:
LCD (internal laptop display) only
LCD + CRT - the picture shows on both displays
CRT - the picture shows only on the external display, allowing you to set a different screen resolution, equivalent to the external monitor's optimum resolution.

Samsung crt 591s blank problem

This eventually happens to all CRT monitors. Either the flyback transformer or some other critical componant has failed, and the screen cannot produce a picture. It might be an easy fix, but it would be better to get a new one.

Many screens on one monitor!

Your monitor is malfunctioning and requires servicing. Unfortunately there is no software solution, and no monitor adjustment buttons will control this problem. Due to the high cost of replacement parts and service technicians, it may be more cost effective to buy a new LCD monitor. Sorry to be the bearer of bad news :(

NEC LCD1712 Monitor Not Working I am having a rather peculiar issue with my NEC LCD1712 which I am currently using as my secondary monitor. It works perfectly fine as I boot up the computer. It displays "welcome to windows!" and all that jazz. However, once I log in, it reverts to just a black screen. I believe it says "no signal input". I am not sure when it started, but I noticed that the display of my primary monitor was shifted over to the right for some reason. I started messing with my graphics card's software "Catalyst Control Center". I used the "restore factory defaults" option and it rendered my NEC monitor black. Thank God my primary monitor was just fine and I was able to fix the image shift later. However, now I cannot for the life of me find a way to get my secondary monitor back up and running. All of my drivers are up to date. I have tried adjusting the resolution and refresh rate of the monitor. I have tried duplicating the displays and making adjustments with my primary monitor. If I only have my primary monitor plugged in on startup, it will behave the same (display up until the log in screen and then blackness). I find this problem to be both peculiar and extremely frustrating. If anyone out there has a solution, it would be greatly appreciated. Here are some specs: Operating System: Windows 7 Home Premium 32-bit System Model: Vostro 230 Processor: Intel Core 2 Duo CPU E7500 @ 2.93GHz (2 CPUs), ~2.9GHz Memory: 4096MB RAM Graphics Card: ASUS EAH5750 Series Primary Monitor: DELL E2210H Secondary (Faulty) Monitor: NEC LCD1712
