I have 2 SMPS powerbricks ,110V-240V to 24V DC @ 5 or 7A (too late to check ) for a 30" 1600p Korean IPS, they both always overheated a lot, and the monitor ended up dying, and I found a fried smd inductor just inside the powerboard of the monitor.
Not sure if it was the external PSU that did it or not (I'll post about that with pictures tomorrow, hoping to fix it).
Anyways I have an internal PSU from an inkjet printer that puts out 5, 30 and 35V, and its probably a lot 'cleaner' than the above powerbricks, I'll post pictures later.
I would like to get 24V from it and try that on the monitors powerboard and see how it acts vs how it acts still when powered from the powerbricks....just to see if its some rippple/noise issue upsetting the powerborad (I'll post those details in another thread)
So whats a good way to do it ? 30V to 24V, and have it be nice and low ripple still ? I have some know how and a chest of parts/components. I think I have a 7805 regulator, if that would get me to 25V
