Question about NEC Computers & Internet

6 Answers

I have 4 NEC LCDs. In moving one of the NEC LCD 1990SXi displays recently, something happened so that the frames around Windows aplications are now distorted. The frames are supposed to be blue but a slight magenta is coming through on the edge of the frame closest to the application being viewed. Also, when picking colors, cyan is now gray and no cyan is seen on application color palettes. The minimize button has a sharper contrasting highlight within. I looked at OSM Tag 6 and settings appear normal. Please advise.

If Cyan is gray, and blue is magenta, that means that you lost the Cyan channel on the color scales and color tracking.

If you are lucky this is caused by a misplaced ribbon cable. Otherwise this is caused bya faulty digital board aor a defective LCD display.

You can test the display using a software like : |MG| DisplayMate 1.30

If this happend just after moving it and it is an lcd the problems you are discribing sound like a bad connection on the back of the lcd itself, unlike crts if you see a distortion like that it may also be board inside the monitor that converts the signal to picture and please people on here either read the full post and reply with stuff that is relevent (this is monitor issue not computer issue and it is not a crt problem cause it is not a crt)

Hi So now we need to know if power is getting to the cd and hard drive. Without a power supply tester it will be hard so I"d take the power supply out and ask my local pc repair shop to test it for me. If it's good then I'd be thinking motherboard. Since neither the cd or hard drive are detected it wouldn't make since that both ide cables had gone bad. I"ve found some info at http://support.dell.com/support/edocs/systems/dim4700/sm/adtshoot.htm#wp1054081 
which has trouble shooting light codes. I"d be interested in what the error code on the lights is. It also has diagrams for those of us that don't know about the inside of pc's. 
The way I troubleshoot the motherboard is to take everything off the board, then one at a time reseat the RAM then try to power on the mb and listen of beeps. Then hook up the ide to the cd and listen for beeps. then the hard drive and listen for beeps and look for messages on the screen. Let me know what the status is.
Thanks,

    Make sure the hard drive is connected to the ide cable that has a blue end. Don't connect anything else to this cable. when the pc is booting up watch the screen for the option to enter setup usually Del, or F2. Once into the bios see if the boot options are set to cd first and ide 0 second. You can also see if the hard drive is being detected in the bios.
    Hope this helps. Let me know.
    Thanks,

Hi and welcome to FixYa,

Initially, would venture a possible loose or partially disconnected cable internal to the unit. Of course it is also possible that a pin in the video cable is bent or out of place or worst broken. best course of action is to perform visual inspection of these possibilities.

Good luck and Thank you for using FixYa. Happy Holidays.

Check that all the connections from the PC to the monitors are tight and snug, go into the display properties and check that all of them are displaying the correct colours (for example 32bit on each) if you have still no joy after this then i would suggest you remove all but one of the monitors, reintall the graphics drivers and set all of the monitors again

kind regards

It sounds like the polarizer filters are starting to ware due to heat build up, if you remove the lid and the main booard, there is a white plastic mesh cover over the lcd panels, you can remove this and adjust the polarizers for the red, green and blue lcds to adjust the black level, there are 3 hex bolts holding a plastic frames which in turn hold the pre polarizer filters, buy slightly loosening the bolt you can slide the plastic frames left or right to adjust the levels, buy you should mark the position before you start. this may not solve the problem but may help to improve it, unfortunately these projectors require special software to make electrical adjustments which is hard to get hold of.

Lcd has moving horizontal lines.zero clearance


Hi,
It is usually a bad contact between the driver circuitry and the display panel itself. This happens because the contacts are secured by pressure, not gripping or soldering as is true with most other electronics; this is a major failure point for LCDs--and one of my biggest gripes about them.

One relatively easy test for this problem is as follows:

With the unit on, gently grasp the left and right edges of the display. Gently twist the display (no more than a few ounces of pressure) as though you are wringing out a towel. See if the display flashes, changes, etc. This may even fix the problem by "wiping" the contacts of dirt or oxidation.

its a common problem of the video hardware in the laptop - it hasnt the ability to split the video "overlay" (often its decoded by something in the video chip, or at least a seperate bit of software and output seperate from the usual, slower windows & images data stream) off to the second screen & you just see the frame of the player.
if you set the external output to be the main/primary, or sometimes only active screen, it should work. you might also have a chance if you make it an extended desktop rather than a cloned one, then moving the player window entirely onto the projector's "screen"

Thinkpad T61 Display Problem


LCDs are not repairable, it is something you need to replace when defective. They also happen to be very very expensive to replace.

Is the screen cracked at all? cause sometimes when laptops get bumped, it is actually just the lcd cable inside the laptop that came a little loose and isn't making a full connection. If the screen isn't cracked or anything I would at least look into a possible loose cable first If you are not comfortable taking the laptop apart, I would bring it to a computer shop and have them take a look at it as some laptops can be complicated to open up. They shouldn't charge you more than about $40 to take a look at the lcd cable, they are normally pretty quick to get at. It is worth a shot as lcds typically range from $400 - $1000 and to have someone install it would be probably another $50-$100

hope this helps a little

NEC MT800 Projector with Vertical Lines in picture


The ghosting problem is a combination of both the lcds and driver boards in which case neither need to be truely replaced.. They use a specific voltage to transmit data to the lcds.. Each lcd is different and the driver board is programmed by the factory for the EE v.com setting. Unfortunatly with nec, they do not offer a service mode to go in and adjust the ee settings to correct the electrical convergance. So the only way to fix the problem is to replace the lcd with a newer one who wasnt worn out from long term heat.
