Samsung 225BW power supply failure

Samsung 225BW, manufactured in March, 2007, Model no. LS22DPWCSQ7EDC

All electrolytic capacitors, except for the main rectifier capacitor, in the power supply had failed. Replaced with Nichicon KY of similar values. C304 and C305 replaced with 470µF and 220µF respectively due to lack of more fitting replacements. They are connected in parallel. C112 successfully replaced with a 220µF part.

Several capacitors were failed on the logic board as well, causing issues with screen wake-up from sleep, as well as occasional flickering.
