Monitor went dark

Started to have a sudden problem, noticed a reddish tint when i start up the computer the monitor blinks and goes dark, but not completely black, so i can see a little through the black. restarting doesn't always help.it still works in that i can still log in and see the start menu pop up if i use the keyboard. i know it's the monitor and not the vid.card. can anyone tell me how to differentiate whether the problem is the inverter or the backlight?

You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight. It could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, this is the most likely case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Is the monitor still under warranty? (probably only the first 12 months)

Try connecting the monitor to a different desktop/notebook computer, to see if it is fine.
If it is, you have a problem with the video-card in your computer, not a problem with your monitor.

There are "capacitors" inside the monitor, that serve to supply "smooth" and "ripple-free" power to the electronic circuits. If you have "bad" capacitors, they are not doing what they should be doing, which causes the electronics to malfunction.

So, if your monitor is a CRT monitor, it's time to responsibly recycle it, and buy a new one.

If your monitor is an LCD monitor, take it to any TV/video repair shop, and pay them $25 to $50 to "inspect" it, looking for "bad caps". Or, spend that $25 to $50 to buy a new LCD monitor.

My acer al1715 has a pink tint. It started


This is a low-end monitor and the image processor is failing. You will require a replacement but since the monitor is low-cost, it is cheaper to simply by a new one.

Red tint on Viewsonic P930b


Hello,

We do a lot of LCD monitor repairs and usually when you get the red tinted display it means the backlight tube is going out. This part is like a very small fluorescent tube just like in you office lamps. The tube is part of the display section and is very hard to replace. You can check the power supply first just to be sure. We have a dis-assembly/repair guide on our web site at: www.ccl-la.com/badcaps.htm If you find any bad capacitors you can change them and check but I would be it is the backlight tubes, if so just replace the monitor.

That's better.
Yep, 95% chance it is the power inverter problem.
If you don't remember the screen having a pink tint or flickering for a while or being dark at the middle top or bottom before it went, then your bulbs should be okay.
It will need at least all the capacitors replaced.
I fix many of these types on ebay.

LCD TV Acer is fading out


If what you are saying is the screen shows up and then goes dim or starts dim, and you can see a dark image (maybe reddish in tint)...

Your problem is a bad CCFL (Cold Cathode Fluorescent Lamp) at the top of the LCD panel.

You can find many websites that sell these parts, but make sure you have the right model.

If you feel comfortable with working on components, you can replace this part yourself. Otherwise, you may want to pay a technician to do it. Make sure to get a fixed price quote before authorizing the work.

Here is a website on LCD repair for laptops, but it the same principal for most LCD displays (TVs).
