Re: Dell U27173HMt 27 inch screen flickering and lines

@pronester did you have any luck yet? I have a 2717 that intermittently does this, it will have a similar display and also emit a hissing type sound. Pressing the front power button off and then back on typically resolves it (sometime s few time) so I suspect that something is on its way out.

CHeck the voltage output of the regulator first, if it is giving 3.3v then this is not your issue. I actually replaced mine by wiring in one of these [url]https://www.ebay.com/itm/MINI-3A-DC-DC-3V-5V-16V-Converter-Step-Down-buck-Power-Supply-Module/273523150907?hash=item3faf40103b:g:CWoAAOSwVE9b0BF~:rk:3:pf:0[/url] configured to output 3.3v
The monitor ran fine for three weeks like this while I waited for the correct ordered part. I suspect that it would have run indefinitly with this as wellRe: Dell U2312H Repair<br /> <br />...voltage output

Re: Dell U2312H Repair

Just a shout out to doomsweek, I have the same monitor that was occasionally not powering up, initially I was looking to replace all the caps and then when googling the power board I found this post. My 3v regulator seems to be intermittent, currently I have hard wired a small ebay sourced switch mode regulator module set to 3.3v and it is currently working perfectly - just awaiting a new G1084-33 that is on order (stupid shop in my country says I need to order minimum 20 units though)
