Strange distortion during power-on/wake - BenQ XL2411T

[ephemeross]

I've had my BenQ XL2411T for a couple yrs now and never had an issue with it... until a few weeks ago that is!
If the monitor has been turned off for a while, or left in stand-by for a while, and then is powered-on/awakened it will do the following: https://youtu.be/AYHJET7zBWY

It's connected via Dual-link DVI @ 144hz, I've tried 120/60 and it does the same. Trying a Display Port to HDMI cable tonight to see if it still does it in the morning.

It never used to do this and my secondary screen (GL2460 @ 60hz) is still working perfectly fine. The monitor works like it should once it's done "scanning" for the image, no artifacting, glitching, etc.
Help!

that looks super weird, assuming gpu is fine, I would lean towards faulty capacitors taking forever to get to right voltage or is about to die. If you know what you're doing I'd take a look inside. if you don't please dont try it, there are very high voltage capacitors in monitors that could quite easily give you a hell of a shock if you aren't careful.

Yup! faulty capacitors! I had the exact same issue on my (then) 5 year old monitor. Took it to an electronics repair guy down the street cost me 10euros for the repair

Okay that's reassuring, might be an easy fix by the sounds of it.
Thank you both very much!

if you know what you're doing yes it is

it will involve some handy dandy soldering skills but its nothing too difficult if for a diy techy guy, get soldering iron, some flux, solder and new identical spec capacitors off of ebay, over all I'd say less than £30 all together + hour of your time.

Good luck.

Update: Opened it up, found the culprit(s), ordered a pack of 5 samsung capacitors of the same spec off of ebay, replaced two of them in the monitor and it's been working like new for the last few days

Already had a soldering iron etc. so it cost me a total of £3.29 to fix and I have 3 spare capacitors left over just in-case.

Thank you very much both of you!
