Hello

You have capacitors on the monitors power supply that have changed value. Soon they will keep the monitor from turning on at all. Send it to a company like mine or take it to a local repair person.

No built in speakers. There is a sound bar that you can get the attaches to the bottom of the screen to add speaers to the unit but it is sold separately.

Inside there is a IC chip on the power pack that goes bad, replacement is called for also look for bad capacitors when you are inside looking around, those need to be replaced as well
hope this clears things up. dells third party who built these units did a rotten job on this model. that chip always fails.

First, find a sturdy flat surface. You will be laying the monitor on it's face - face down so get a towel, blanket or something soft to cushion the monitor on the flat surface.
Lay the monitor face down on the whatever cushion you chose.
There are two black machine screws on the back on the plate that is part of the stand. Remove these screws and the stand will slide free.

These monitor had a problem with there power supply. I have 2 of these and both had same problem . If you go on e-bay you should still find people who will fix just the power supply or sell you a kit or for that matter just the one ic that causes the problem . (you would replace bad caps you self) If you replace just the bad caps you will find it still will not work with out that ic

Hi pcpiuk

If you have a multimeter, and want to get into the electronics of it all, you could rip the covers off and sus it out. Here is a pictorial guide on whats in it. You need to check the power supply for operation. If it appears to be producing voltage(they usually do or they dont) then it will be ok. The common cause of failure in the power supply is the regulator IC ICE2AS01 an 8-pin DIP chip, and resolder the entire PC. Around power devices I use solder with 2% silver content as it creates much tougher solder joint. If the power supply checks ok, then the inverter is the next spot to check. Just replace it if it appears to be the problem. You can get spares to rebuild the power supply and even new boards from ebay or Dell direct.
If you have any trouble getting parts, comment back to me here.
I am more than happy to answer any other questions you may have about it, please get back to me here, or use the ASK function to go straight to me :) If you are still unsure, have problems, or we need to look at the situation more deeply, then before you give a rating for this advice, hit the ASK button Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you.

(Please be advise that if you don't have the knowledge, the proper skills and the right tools to open the back cover of your monitor and replace its part...don't risk it...
Otherwise, bring your unit to a credible technician and avail of warranty if there is any.....) If you have guts.. then do the following steps..

You said your monitor will blink but no picture display... well, there are possible reasons why this problem occur..

1. Open the back cover of your monitor..Check the power supply section for possible loose connections and blown capacitors.. Resolder any loose terminal connection on the pcb. Check for any blown capacitor, replace the capacitor with exact value, and also replace any bulging capacitor..If you have successfully replace the parts you can try to turn it on and connect the vga cable in it to the video card of your computer. Turn on also the cpu, if the monitor led turn green and the display came out..that fixed it.

2. In case you have successfully repaired the power supply section and the led of the monitor stays green.. then the problem will be in the inverter board section....Turn off your monitor... open the back cover...on the inverter board section.. check and replaced burnt or overheating high voltage transformer..if one or more of this overheats, it is enough to affect the supply current from the power supply section and that may cause to blow your capacitor...If the ballast transformer is working fine the last thing to check is the backlight inverter (the light that illuminate causing display in your monitor) Replace any busted lamp.. that should fix the black screen on your monitor. ..

If you find this information very useful..please be kind to rate this solution and vote for this on the help below...thanks..




Much appreciated if you rate this help...thanks...

Sounds like the monitor cable has a short or loose connection at computer or monitor side.
