Coppell TV Repair offers you power supply board PK101V2560I / FSP300-4F04 shown on the picture.
The board comes from a brand new Sanyo DP55441 chassis P55441-03 liquidated and dismantled due to damaged display.
We tested the TV before dismantling it and can confirm it was in good working order.
Before purchasing the board please make sure your TV has the same board inside!
