Just need to bypass this low voltage protection ig...

It works fine between 15-19 volts but starts to go into protection on off on off mode below 15 volts with no load
I think it has to do with some sort of short circuit protection because low voltage no current causes it to go into protection but im scared of touching RX85 and RX94 current sense resistors because this psu can go upto 120 watts so it will nuke itself at lower voltages...

Modifying R76 (472) does change the voltage a bit but the supply makes a ticking noise and goes into some sort of protection when the voltage drops below 18 volts so i can change voltage between 19 and 18 volts 😂....
There must be a preset resistor that does the UV/OV protection or ig R76 ain't the one im supposed to change

Edit: Putting a load on it stops the ticking and stabilizes the voltage but any no load voltage below 15 volts causes it to go tick tick mode
R76 is the most effective at changing voltage, the rest have little or no effect at the right side...

$3 dollars there are 30$ here (Inflation sadly sucks here)
Plus i'm not going to spend money on this Psu as it's a decade old one and i'm just trying to find a use for it...

The opto coupler is directly connected to the double diode 3 pin ic
Removed the sticky glue at the top side and no I don't see any zener
I attached a schematic from TLW03WA ic (similar to mine) from it's datasheet...

I'm trying to turn this old dell laptop psu into a variable power supply (5-19.5) as i have already modified a few power supplies before and now i want to do the same with this but it's a bit complicated
The pic below has an op-amp ic (Z103WA) that does the CC/CV adjustments and a double diode 3 pin ic at the far right
As you can see there's no TL431 or Switching ic self-regulations that i can tweak easily.
Any help would be appreciated
