2709W, will not power up

Hi zulu11,

Request you to try following the below steps to see if it works:

(1) If you have a known good monitor try swapping the existing monitor and check if it works.

(2) If alternate monitor is not available, please turn on the computer and remove the monitor cable(the cable that connect the monitor and the computer)

(3) If colored lines come up then monitor is working fine.

Do reply with your findings.

Maybe see my suggestion re similar post above ?  Good luck.

Hi zulu11,

Thank you so much for trying to use a different monitor. I also request you to turn on the computer and remove the monitor cable (the cable that connects the monitor and the computer).

Do let me know what happens after this.

Hi Kiran,

I removed the hdmi cable and there was no change. I have also tried using dvi cables and three of my computers with no luck. I think the problem is power supply related, how do I open the casing to check fuses or capacitors? Thanks for all the help everyone :)

Hi zulu11,

We have tried almost all the steps but nothing worked. This could mean that the Monitors might have failed. I request you to provide the Monitor Order number through private message so that I can check and let you know what needs to be done.

If you don’t have the monitor order number I request to send the date of purchase, Place of purchase, customer name, Shipping address, phone number, email address, Monitor Model, Monitor Part number and Monitor 20 digit PPID number through private message.

I have added you as a friend. Please accept my friend request by clicking on my name highlighted in blue and then click on “Friends” tab at the top and then click on “Request to Review” and finally click on “Accept” button. I am sending you a private message as well. Click on “Inbox” to respond to the message and provide system’s Service Tag and contact details so I may access your system records and check for further course of action. You could also click on Start Conversation to send a private message.

Thanks for your help Kiran, unfortunately the fact that Dell does not provide any spares or after warranty service on monitors such as both of mine (not Cheap ones) is still very poor in my opinion and will prevent me from using Dells product again, I would not able to recommend them either. I am happy to pay for service or repairs as I can accept fair wear and tear. I cant believe that 2 monitors failed with a week of each other and Dells solution from the support team was throw them away and buy new ones! Kiran thanks for the links to the 3rd party repair businesses but they are of no value as I live in Australia and they are in USA. Local Australian repair agents have told me they cannot get spares from Dell? Why would I use this product again?

Just an update, I repaired both of the monitors myself. The parts cost me 34 cents! I traced the fault within an hour.

Hi zulu11

My 2709wb monitor also failed recently, with similar symptoms to those you described. You say you fixed it yourself - would you mind letting me know what the solution was? I would really appreciate it.

Hi there

I traced the fault to the secondary psu (on the big pcb) The hardest part was getting the monitor open! 

Hope this helps

Thanks Zulu11. Is it possible to be a little more specific?

I got the back off mine, with a bit of coercion, and verified that the mains filter board was okay. This implied the fault was somewhere in the switchmode board, but I couldn't see anything obviously wrong there: no bulging electrolytic caps etc.

What was the 34c part you replaced? It would help to know this, rather than have to try to trace the circuit, replace all the caps, resolder the board etc..

I'm thinking that if you found the same fault on both of your monitors, then it may be an inherent weakness in ALL 2709's, including mine. Knowing this would be useful for all the other 2709 owners who suddenly find themselves in the same situation. It is unthinkable to throw away what would otherwise be a perfectly good ( and bloody expensive! ) monitor if it only requires the replacement of a trivial part.

Thanks again for taking the time to answer - it is really appreciated.

Hi, I have 8 Dell 2709W and one just died. I heve the skills to change the capacitors but I can't see how to open it. If you can send some info about irt will be very helpfull.

Regards

Use a thin bladed tool (a small paint scraper works well) and push it into the seam between the front bezel and the case. It should pop apart. Draw the blade along the seam until the front bezel and case are fully separated. Use care around the touch controls, because there is a ribbon cable there that joins the front bezel to the chassis. The video linked here should give you a good idea of what to do.

Good luck.

I have had one of my 2709w 's just die…will not power up. Would like your step-by-step instructions please. I would rather attempt a fix than replacement. Thanks
