Black/very dim display

The screen is almost black. You can barely see it, but has it not usable. You can't see any part of screen during bootup. Display on HDMI works fine. The screen started to have lines, and now has gone dark. Computer works fine. I replaced the screen (panel) and there was no change. It appears there is no inverter, so I have no idea what to do now. Computer is almost 2 years old. It has 1366x 768 resolution, AMD processor and ATI Video.

It is perhaps the flex cable. The screen may not have been bad. The only way to tell is to replace the cable.

Qosmio F50 very dim display issue

Hi everyone
Recently my Qosmio F50-10z has started suffering a very weird problem. Often the screen goes absolutely dim. I can see a very very faint image if I concentrate very hard. External monitors when connected stay well lit and bright. The most weird bit is that when this happens I have to literally slam the lid shut and open the lid immediately to make the screen light up again.
I know it is either the inverter or the screen cable. My question is how do I find out whether it is the VGA cable or the inverter and where do I buy the part from!
Please help!
Thanks!

In my opinion its an FL inverter issue since the picture on the external monitor is ok.
The FL inverter controls the display backlight and the issue sounds like FL inverter malfunction.
You can purchase and order all compatible parts from an local ASP.
The authorized service partner would be helpful and could also replace the part.
I would recommend this because notebook disassembling is very tricky.

Hp color laserjet 2600n, very dim grayish film when printing black only

For some reason, my hp color laserjet 2600n has started printing with a very dim grayish film over each page. I've had this printer for about a year, and it didn't do this at first. Does it no matter what program I print from. I'm sure it's a setting issue, but haven't been able to figure it out. Any ideas?
And, when I select to print in black only, it still prints the color on web pages. Is there a way to print from only the black cartridge? These are the options in the printer dialogue box under color: print in grayscale, black only, 4-color. Under these settings are other options, edge control, half-tone and RGB color. I've tried each setting individually and still the gray film. The only other possibility I can see is under Print Options, it has draft quality or image quality. I've tried both and still the film.
Have any ideas.

1. take out all of the ink cartriges and look at the big black roller on the door for streaking, if streaking, clean with a lint free cloth dampened with windex (window cleaner) then close the door.
2. let it run to initializing.
3. open the door and look and the black roller on the door to see if you have streaking. If no streaking put one cartridge in and close the door and repeat the steps until you find what cartridge is causing the problem.
I did this and found that my cyan was creating the lines on my paper. I cleaned the cyan roller with a Qtip and some rubbing alcohol and it works fine now, no more lines on the paper.
Cheers

Pls its very urgent - i dropped by iphone 3G and the display became very dim soon after and it still remains the same - pls advise what should be done to bring the display back to normal

sounds like you broke the display when you dropped it. There's nothing we users here can do for you.
Since the iPhone warranty does not cover accidental damage, you will have to pay to have your phone repaired or replaced. You can bring it into Apple for an out of warranty exchange in the country of purchase, or you can find a 3rd party iPhone repair store in your area.

T500 display very dim , possible mechanical failure?

Hello,
It seems that my T500 LCD display has become very very dim, the display is barely visible.
After repeatedly turning it on/off it suddenly was able to display full brightness during one debug session... I even restarted it / shut it down multiple times, and it worked. HOWEVER, it seemed that the brightness was dependent on the angle at which the LCD was hinged, if I opened it all the way the screen became bright again (something over 90 degrees), if i started to close it (roughtly 30 degrees?), it became very dim. To me this sounds like a mechanical issue, possible a loose cable. Unfortuantely, I was not able to reproduce this again after this debug session, I suspected that as i was transporting it to/from work i may have changed some internal mechanical configuration.
Is there an actual 'mechanical' switch which drives the LCD brightness depending on the angular position of the LCD? I tried reading through the service manual here:
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/43y6630_04.pdf
I couldnt find any mention of any sort of LCD brightness mechanical hinge switch
=== other info===
From googling, the issue could also be :
a) inverter issues
b) backlight issues
c) fuse on mother board?
As a quick test, i hooked up the VGA output to a secondary monitor and that works fine, so long as I go to the BIOS and set it to boot to the VGA first as the primary display.
Any suggestions would be great!

Try going into the BIOS and switching to Integrated Graphics only. Does the screen still remains dark/dim?

Screen is very dim, black screen

Hi, my wife first edition ipad is 4 years old, the screen is very dim, you can see the screen righting and apps if you use a touch, I have done a system restore and a full reboot but is still the same, I have also turned the brightness up still no good, could really do with some help & please don't ask me to hold buttons down, already done cheers tom

Jeffdesersa,
Don't worry, ok? This is scary to see but we will help fix it for you. How are you trying to activate the phone? Have you tried connecting the phone to a computer and using iTunes to activate it? Activating that way may just do the trick!

Very dim screen on MacBook Pro - how to prove it?

I bought an MBP about 4 weeks ago (just before the new rev came out, so this one does not have LED backlight) and have mostly been using it connected to a 23" cinema display.
When I was using the built-in screen the other day I realised it was very dim even at full brightness, with very narrow viewing angles, dark corners, and a noticable brightness continuity down the left hand side.
Now the shop I bought it from doesn't have any 'old' MBP's to compare it to, but comparing it to my 4 year old Thinkpad it's clearly substandard, and to my eyes it's bad enough to be defective. The shop on the other hand say it's 'normal' but suggested take it to an apple service center to get it tested.
So, does anyone know what the actual specs for light output (lumens) of a CCFL-backlight MBP are? If I don't have that number, how can I best persuade Apple that this screen is defective, and not get fobbed off with unprovable claims that it's 'normal'?
Many thanks for any advice.

Re-install the OS from the original DVD supplied, boot holding down c to force the disc start up.

Our mac pro went to a very faint display and we can't fix it.

Our week old mac book pro suddenly has a very faint display, almost all black and we can't fix it. We've re-started etc.

I assume you have tried the "obvious" stuff, like using the brightness buttons (F1 = dimmer, F2 = brighter) or turning up brightness in system preferences>displays. I'm sure you tried all that, but I just had to say it just in case. Anyway, you may want to try reseting your PMU...
PMU stands for Power Management Unit and it is a chip that controls the backlighting of your display (among other things). To reset your PMU do the following:
1. If the computer is on, turn it off.
2. Disconnect the AC Adapter and remove the computer's battery.
3. Press and hold down the power button for 5 seconds and then release the button.
4. Reconnect the battery and AC Adapter.
5. Press the Power button to restart the computer.
Those are the official apple instructions, but I suggest in step 3 you hold the power button down for 10 seconds.
Here is a link that refers to reseting the PMU on a MacBook.

20" G4 dim display

I have read as much as I can on here but need more info. I have an iMac USB2.0 w/20" that is very dimly lit. When I first got it it was not lit at all. I have tried 2 different inverters thinking maybe the first one was bad. The one that came in it was from www.welovemacs.com.
Needless to say, the lady I got it from totally scammed me. She said a tec said it needed an inverter and when I got it, the entire computer had been taken completely apart, including the LCD itself.
A few things I would like to know is the pin out diagram for the TMDS connector and the power connector for the inverter/mic/speaker. I would also like to know how to test the inverters to see if they are working or not. If I cannot get this display working on the iMax I would like to take it off and try to make it work on it's own.
I am very computer literate and can take this thing apart with no problems. I also do SMD rework on circuit boards so I will have no problem trouble shooting.
Thank you in advance for any help but I need more info then can be found in other posts. Right now I am kind of stuck unless I have a schematic or a perfectly working model to switch parts around, and that isn't going to happen
on an odd note, if someone knows where to get the mini jack for the apple pro speakers, I would like to replace that as it is broken beyond repair.

If you find one, let me know. If you find two, send me both and your mac and I will do it for free (minus shipping of course .
I would do mine first to make sure It comes off ok. The resoldering is easy, the removal is the tough part as I believe it is a thru-hole versus surface mount.
Other then that, I am now trying another inverter board. From there I will try either a new lamp design (CCFL) or even LED's to light up the iMac LCD.
I am also looking into replacing the LCD assy with one from a G5. But the G5 uses LVDS technology for the feed to the LCD while the G4 uses TMDS. I do not think they are compatible. Although I have found conflicts the they are. But that is for another thread.

My screen is very dim

My screen seems very dim on my MacBook Pro and MacBook Air, even under direct light the screen I have to strain to see the screen.

My screen is also going dimmer and I have the f6 setting at highest setting. Please tell me how to adjust in sys. prefs?
F6 does not adjust the screen at all. F6 is foir the adjustment of the keyboard backlighting.
Use F2 to brighten your screen.
Under Sytem Preferences, Display pane, also de-select the Automatic brightness setting. This will permit you to adjust the display to your liking. However, it also generally consumes more battery power (if running on battery) to keep a screen at full brightness manually.

Dim display lenovo t 400 lcd

hi....
i dont know why and how this happened but it so happened that my thinkpad t 400 display became very very dim.
i tried increasing the brightness but it was of no use.Also the various lights that are present on the display panel(wifi,bluetooth,battery,charging,sleep mode,...etc) are not glowing any more.The screen has become very very dim.
Some people whom i have enquired have told me that the THT bulb might have fused.........................................is it so....................................................whatever it is please suggest me some help...............................................I need my laptop very badly at this point of time

If the front panel indicator LED's are off and the backlight is dead, then it sounds like something's wrong with the cable or motherboard. Whether or not the lamp is dead is uncertain.

Dim display on Zen Mi

My display is very dim all of a sudden.
Anyone else experience this?
This is my second Micro, the first one froze all the time.

<FONT color=#3333ff>If you have tried resetting the player and that has not helped it could be the LCD (Liquid Crystal Display) which it sounds like it is, then have you tried bringing up the contrast? If that fails it could be a weak connection between the PCB (Printed Circuit Board) and the contacts of the display. Many items like this use a conducti've rubber strip that is flexible, sometimes these move (e.g when placed in your pocket and some considrable force is exerted on the player) this happend to my old mobile phone. If this is the case there is not much elce you can do except contact Creative and arrange or a repair or replacement. Weak partially displayed looking characters often have the signature that there is somthing arry with the display.

Thinkpad W500 screen - seems very dim. typical? faulty?

Having issues with the apparent brightness of my Lenovo W500 (suspected Samsung display) in reasonable ambient light levels, I thought I'd try measuring the lux with a tool I found at ->http://www.tuug.fi/~toni/serendipity/index.php?/archives/12-Luxus-light-meter-desktop-widget-for-N90...  -- just for a more objective, albeit uncalibrated view on brightness.
In each case I placed the proximity sensor directly over the panel, so it was around 5cm "in" from the edge & displayed an all-white window.
Here's my rough results
Lenovo W500 (full)                            R=083 L=063 T=060
Dell 2005fp desktop (normal)                  R=151 L=155 T=142
old? HP 17" 4:3 (normal)                      R=157 L=143 T=180
Dell Studio 15 1920 laptop led (in dark room) R=104 L=111 T=110
Dell Studio 15 1920 laptop led (full)         R=214 L=212 T=226
Dell Studio 17 laptop led (full)              R=300 L=314 T=297
? HP 19" unknown (low lighting)               L=098 R=107 T=113
? HP 19" unknown (full)                       L=138 R=153 T=162
From this "comfortable" is IMO in the region 130-150 - the W500 fals way way below this.
Has anyone else measured?
What's reasonable?
I believe the spec is around 175-180 -- but that's obviously a calibrated test
The dell 2005fp is rated at 300 yet I score 150 above (though this is NOT on max, just normal)
The dell studio 17 is rated around 317 on full -- and the score above shows this as close
I can only conclude therefore my measurements are in the right ball park
The W500 is on full brightness & using the appropriate monitor.inf under win 7
What I should really do is have a proper colorimiter calibration and measurement done.
The "spec" of the W500 panel is 180-200 I believe - it's clearly not fair to use the numbers literally, but something is very very wrong.
Does this suggest my panel is faulty? To be honest I don't think I've seen a "good" W500 but I wonder if it meets the spec?
Anyone else fancy measuring a "current" laptop for comparison -- especially any other W500 owners (some of which have samsung panels, some have LG panels)

I no longer have W500 but I do remember screen being very dim. Notebookcheck measured a much higher value (130 on average?) even in comparison to other notebooks so I also suggest you try to get a replacement. I guess it is ok to use the manufacturer values when reporting a faulty screen.
