Hi @jumbles44,

What is the model number of the TV?

You said that the “…. power supply voltages were OK.” Does this mean that the Standby Power voltage at the ref point on the power board was checked and OK? The STBY voltage ref point is usually marked on the power boards in Samsung TVs

If it was OK did you verify that it was also getting to the mainboard OK?

Can’t tell you the price of the mainboard as there is no mention by you what the TV model number is, at least not on this forum anyway
