27" TV turned into mood light

Try this before sending a TV to the landfill.

Used a 16' LED strip light from the box store, works well.

Scrap TV lightbox

Gutted an old 27" flat screen, slapped some LED strips inside, taped the light diffuser to the frame, called it complete.

This is the LED strip, I calculated it should need ~ 90v at 3A across each strip as there are 15 LEDs at 6v 200mA ea.

I want to make a light box from the TV frame and light strip,
Can I make the driver circuit stealing parts from the old PSU?

My research so far tells me to do a step-down tranformer>bridge rectifier>filter capacitor arrangement, but I'm not technically savvy enough to figure out what the values of each should be.

The PSU is a 40-l12dh4-pwd1cg, datasheet escapes me.

The parts are from a TCL 55" LCD model 55s434.
