LP3065 top arrea darker - backlight defect?

My monitor has some problems and probably something did get to hot. At first I noticed the left upper corner was darker then the rest of the screen. Later I noticed a bad smell, like a small part of a PCB was much to hot. But what ever had burned, it does not stink any more. After I turned the monitor and the computers off it made a tick-tick sound (similar to a mechanical clock) while booting. The permanent damage is a darker area on the top of the screen. It is like 1/5 of screen has only half the back light as the rest of the screen. I assume the back light is made of several pieces and to the top peace is defect. I have read the durability of the back light is a problem, HP has released a software "HP Display LiteServer" to get the most until the back light fails.

    Looks like the ******** at HP do not provide a service manual for this device. And probably they do not sell inverters. Inverters seems to get broken very often. My last HP product ... **** HP.

What you can do is to remove the back cover to access the inverter board. probably the cause of the smell is burned inverter board for the screen back light ( ccfl ) at the upper portion of the display.you can find the inverter board near the power supply board. usually you will replaced the inverter board since most of the part get fried as will as the pcb pattern circuit board get burnt.hope this can help good luck.

    It is not easy to open the back cover. I removed the only screws I found, removed the handle and some rubber. I do not find a service manual at hp.com.

Assuming you've already checked your driver and system settings, tried a different monitor, and checked the cable and connector pins, this would almost certainly be a problem with the power or signal circuit board inside the monitor.

I have the same problem except it usually happens after Ive left my computer idle for a while... i.e . Overnight, I usually turn off the monitor and I hit the button after I come back to turn it on. I get the same flashing light for several minutes. This has been a problem for several months, but only recenly have i gotten the same error message you mentioned. Each time ive booted the computer up cold or restarted it has worked fine but this time it took longer along with displaying the message: Top Left to Right: SH770 P001 Bottom Left to Right: AU M170EN05 Anyone else who can clear this up?

Chances are that you are not hurting anything with the lower power supply. What is probably happening is most likely two fold. 1. The light bulbs in the backlight circuit may just be wearing out and need replacement, and 2. the lower current power supply may not be capable of producing al the current that the monitor needs at certain times during operation. I would suggest getting hold of the correct power supply module and see where that gets you. If you still have the red outs,replace the light bulbs in the monitor. The only other fault than that would have to be in the video controller. Hope this helps.

IH252 inc monitor bottom half darker than top.


Thin screen LCD monitor brightness controls operate several fluorescent lamps called "backlights" that are positioned behind the LCD display. Typically, they're located around the edges of the screen - sometimes just at the top and bottom, and other times at the left and right edges and others still at all 4 edges.

84fdffef-ec73-450a-8fb9-5901d3322462.jpg
Fluorescent "backlight" lamp, inverter & connection wiring.

The lamps are miniature versions of those sold in stores. They require a support circuitry called an inverter that convert & boosts the level of DC to AC voltage performing the functions of a ballast in a traditional fluorescent fixture.

The reason a part of your screen remains dark is because one or more of the components in the picture above has failed and will not allow the lamp to shine. Replacement lamps and inverters aren't expensive - but requires patience and the ability to disassemble / assemble the monitor (which is usually harder to do than it appears) and solder. They are available various lengths and color temperatures (you must get a lamp that is identical or it will be noticed). If this is a new monitor - you ought to return it for replacement. If used, consider the cost of purchasing a replacement (new or used) vs. repair.

I hope this helps & good luck!

MOST LIKELY YOU HAVE A DEFECTIVE LCD PANEL. Try lightly squeezing the top of the TV. Start from one corner and work your way slowly to the other side. If squeezing the top of the frame clears up the screen problem, you have a defective LCD panel tab. The only true repair is the replace the screen. This cost for a replacement panel could cost more than a new TV set.

Your keyboard has a special "Function key" (printed in blue). It is probably on the lower-left, next to the special Windows key or control key.
You also have several keys along the top row, also blue.
Hold the blue [Fn] and press the upper key that resembles a monitor. Release the two keys and wait a few seconds. If the monitor does not come on, wait a few more seconds, the press the two blue keys again. It will work.
By the way, the fluorescent lamp that creates the "backlight" for your laptop screen has burned out or the cable may be loose.

Screen Half darker


It sounds like your backlight isn't working properly. LCD screens have backlights that illuminate the colors produced upon their surfaces, so that you can easily see the screen without an external light source. In your case, it sounds like your backlights either aren't cailbrated, are damaged, or were produced unevenly.

There is most likely not a fix for this, though most all LCD screens have some form of light distortion. My own LCD screen is slightly brighter around the edges, where the backlights are located, but this is only noticeable when displaying a completely black screen.

Screen is half dark and whistles when battery is unplugged


You could have a defective screen, either a faulty inverteror a CCFL lamp - follow this to determine the fault.

Defective CCFL backlight, it may have the following symptom:
  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering 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 replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, 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 and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Sumsung 930b goes dim,and flickers after about 3 min.


This sounds like the inverter has gone bad. If the bulb were bad only, you would see a faint image on the screen with a flashlight.

The problem is on this monitor, it will probably cost about $100 or so to take it to a shop to get it fixed, and that is nearing the cost of a new monitor.

If you are a little bit handy, and can disassemble the monitor, you can replace the inverter. The hardest thing about this, is getting the monitor faceplate open. Just use something firm and softer, such as a nylon spudger (this is something you can find online) or you can carefully use a thin scredriver. You just have to be careful, those cases are really tight.

Here is a good guide for general ideas on how it is done.

So your sure when you go into the monitor settings, and color, it is set to like 9300k or something? It probably isn't the monitor, because the video games you said display just fine.

Monitor picture goes extremely dark


sounds like the backlight is defective. You can probably get a new backlight online if your comfortable taking apart sensitive electronic equipment BUT you must be very very carefull and handle the lcd with care as you can easyly damage it. Oh one more thing the power supply may also be defective for the backlight. I would contact the manufacture to see about the repair or replacement parts as they should be listed in your operators manual. Good Luck
