prima 26k7e power board replacement or mod

[muzzammil20]

Hi there, i got a prima 26k7e from a friend, said it doesn't power on, thought it would be as simple as a fuse but of course my luck runs thin and 3 components fried so not worth fixing so was asking if anyone know where i can find a replacement or if anyone know the voltages that runs through all of the red wires and if can someone tell me what the brown and purple wire does so i can build one off of another broken tv i have, ill post a picture.

From looking at the traces on the bottom side of the board, the red is one of the power supply output (may be for 24V output for the backlights inverter circuits), the violet is another supply out put (more likely to be 5VSTBY), the brown one seems to the control signal receiving pin which gets the control signal from the main board.
Country you are in?

24volt, mhhmm.... i tried 5 volt to be safe and a blue light comes on but very dim and no response nor picture so i will try 12v then move up from there up to 24v

Those two tall caps for the red wires output on the secondary side, what are the voltage ratings? If they are for 24V then they will have 35V rating on them. If they are 25V rating them the output on the red wires can be 15~18V.
