I picked this monitor up hoping to repair it; when it comes on, it has a buzzing sound that gradually goes a way. The image looks good at first, then the lower half of the image gets darker and starts flickering. I have run it for some time now, and the monitor has not gone dark, and the image is still bright enough to read. I haven't opened it yet, and hoped to get a prelim 'scouting report' from the members here.

Re: HP W2338H flickering and buzzing
Cant tell anything from that picture certainly looks better than the crap laptop im working on.
Dimming and flickering and buzzing tends to be Bulbs/ associated wiring or
inverter transformers.
You need to take it apart and find out what is buzzing - does a noise accompany the flickering - have you any spare bulbs.another panel?Please upload pictures using attachment function when ask for help on the repair

Re: HP W2338H flickering and buzzing
Do you have AM transistor radio? If you do, tune it to the blank station on the dial, then put it close to the panel, apply the power and turn on the monitor, listen for the static on the radio to see if it in sync with flickering on the screen, if it does, then you more likely to have arcing going on in the panel due to bad wiring on the lamp's ends.Never stop learning

Wondering if I could get some insight on a Dell U27HM. First turned it on and the image was completely black. I later realised that if I dragged a window from one monitor to (the broken) other one then smeared colors would appear on the bottom 75% of the screen. After being on for several hours the top part of the screen started flickering showing an image (I have a video of this) and then suddenly the image appeared albeit rather fuzzy in the bottom 75% - image attached - and some hour later it now appears normal
I do have two of these monitors so a compare/swap...-

I have a KOGAN 58' LCD Panel that 'flickers / pulsates' when in energy saving mode.
I've reset the unit to factory default & rerun the initial setup but no change.
IF I choose any other mode, example: Standard, flickering disappears.
I've downloaded the most recent FW for this model from Kogan's website & re-flashed. This initiated a full wipe of the unit, which subsequently led to the setup all over again, however, the issue still remained - screen flickering but only when in 'energy saving' mode.
I've taken the unit apart,... -
