Faulty hp en623aa flat screen monitor

It simply just dosnt have any power, all fuses checked and there are no problems with the board, what in the world of monitors could it be?
It has 2 circuit boards inside (i think 1 is kind of an on board graphic device 4 this screen) the power 'on' switch is connected to this device' circuit board by 3 wires (and connector) 1 red 1 brown and 1 black, i suspect the red and black have obvious purposes but can any1 tell me what the brown is used for? also any help would be muchly apprieciated, thank you.

SOURCE: Faulty Monitor?

I had the same problem, dead p.o.s. I enjoy this monitor, it’s one of the few on the market that are completely flat on the face. Great look! I own two, one used off ebay, repaired. Land fill, no fukin way. Found a fellow who can fix the power supply on ebay, $40.00 . I found a fix here on Fixya. Went to radio shack, better to order on line their inventory for these parts is itty *****, the same size capacitors, only $10.00. Inside in the guts of the power supply the capacitors were bulging and leaking.
Pulled them out and amateur soldering popped in the new ones, replaced 4 of the 6 big fukerz. Harest thing was getting the cover off, slight pry and slide up. And whalla! Good as new. Got 5 years on this one XG-91. Suk me Xerox for cheep o Partz! Burn the fuckerz that don’t make things to last!

SOURCE: Monitor comes on, shows the screen for a second then goes blank

The main problem is here is the graghics card its needs to updated and make sure the pins are alright on the display cable. Also you need to uninstall the integreated one that came with the PC first before you install a graghics card. so right now you need to put the display back to the motherboard display then when you have that done then you put it in the grafics card you have then it should something i had the same promblem for awile i couldnt figure it out either. Hope that works for you. Good luck

Just tore mine apart so here is some help. You need to remove the two screws on the back of the case on the bottom. Then you remove the front cover it slides toward the top of the screen then lifts off. You can pry it off if that doesn't work. If you want to seperate the screen from the back cover you then need to remove the swivel mount and the other two screws from the back cover.

SOURCE: I own a XG-91D monitor that the screen goes black

Hello,

Replace thee 1000uf caps too. A capacitor meter will not test the ESR ( equivalent series resistance ) of the caps the cap meter will show them to be good but an ESR meter will show then to be bad. Also be sure to use low ESR caps. If you use general purpose aps like from Radio Shack it can damage the board board because of the ESR rating. The temp rating needs to be 105c or the new caps will blow out within a month because of the heat in the monitor case ( No fans ).

I hope this helps, if so please rate our solution.

You may also have to check the IC/Transistors Inverter transfomer drivers, also should Ohm out the resistance of the transformers.

My dell latitude d800 dosnt start. no cursor no splash screen ..only lightning some buttons..


Hi,

If you see power lights but nothing appears on the screen, it could be a "POST" (Power-on Self Test) problem or simply LCD problem.

Here are some steps that you can try. One of these may work on your case.

1. Remove the battery and the ac adapter then press the power button for at least 20 seconds to drain electric charges left on the system. (You may need to repeat this step to get it work.)

2. If above step doesn't work, try to plug in an external monitor and see if you get display from the external monitor.

3. If you get display from the external monitor, I'm sure your having problem with the LCD components. In this case, check and replace faulty LCD backlight, LCD cable or LCD inverter. The LCD inverter is often a culprit.

4. Try to reinsert the memory module/s (RAM) of the unit, try using one RAM at a time to see if it works. A faulty RAM will cause the laptop not to POST.

5. If reinserting the RAM doesn't help, most likely your motherboard needs to be replaced.

Hope this helps.

LCD screen totally white when turn on


The HP is a flat screen monitor used with many desktop computers. When the LCD on your HP monitor goes white, it is an indication that your monitor's inverter board has gone bad. The inverter board is a small circuit board that transfers power from the monitor's main circuit board to the LCD screen. Replacing the inverter board means dismantling the HP monitor.

1. Power down your computer and unplug the HP monitor cable from the back of your desktop. Disconnect the power cable from the back of the monitor. Relocate the monitor to a flat work surface. Place the monitor with the screen facing downward.

2. Remove the Phillips-head screws from the monitor's base stand and from the back cover. Lift the base stand off of the monitor and remove the back cover. Peel away the foil from inside the monitor around the internal circuit board.

3. Locate the inverter board near the bottom of the monitor's casing. Unplug the power cables from either side of the inverter. Loosen the Phillips-head screws from the inverter board. Lift the old inverter out of the monitor's casing and set it aside.

4. Place the new inverter inside the monitor. Replace the Phillips-head screws and fasten it in place. Reconnect the power cables to the connectors on each side of the new inverter. Replace the foil around the outside of the main circuit board.

5. Replace the back panel and base stand, and their retaining Phillips-head screws

I hope you find it very helpful.

Power light on flashing but no screen


Hello.

There is either a problem with your monitor, VGA cable or PC's video connector. Try another PC or another monitor to narrow down your problem.

If another monitor works, swap the VGA cable on your old monitor.

If another monitor doesn't work, your video connector is faulty.

Hope this helps.

HP vs19e Flat Panel Monitor. model HSTND-2LO7, product# EN632AA made March 2006. I have no power indication. Checked internal power supply connections and PC mounted fuses. Tested operation with another...


If it's under warranty, then take it back for repair or replacement. If it's not under warranty then plan to buy a new one. Unfortunately, in the modern world, faulty electronics without a warranty on them are becoming increasingly known as "throw away items". This has started to happen with monitors. They call them throw away items because it typically costs just as much or more to have it repaired as it does to replace it with a new one. There are several things that could cause the monitor to go black: Bad inverter, Bad back-lights, Bad throwback (transformer), Bad LCD, & etc. Look for any burned resistors or popped capacitors on the circuit boards also. I've had a few monitors where all I had to do was replace the faulty resistor or capacitor and it worked fine.

Screen is black


The problem is a back-lighting fault. This fault can be a faulty inverter board os a faulty CCFL lamp.

Blinking screen


I'm seeing alot of leaking caps on the power supply cause this issue. It can also be T-Control board faulty, or even main board. Is it flickering constantly, or once warmed up?

Part no. for a Transistor 27611 637205


I was looking for the same part and discovered that it is an AP2761I (capital i not one at the end). Documentation on it can be found at http://doc.chipfind.ru/a-power/ap2761ia.htm.

I haven't yet found a supplier as, in this Dell E153FPf 15" LCD monitor, neighbouring components R856, C856 and R861 are so burnt out that I don't know what values to replace them with. If in return you could tell me the values of components near your AP2761i-A, I would appreciate it.

I had the same problem before. I open my set to find out the faulty component are at power supply main board.

You can visual check first.Color changes and bulky form on cap and burnt resistor easily.
Have a try.
