Hello sorry about the late response I bought a new main board and paperboard from shopjimmy.com and now I have a constant red which I know it means it has power but when I hit the button it will go away for 3 seconds then come back with a constant red. I hear no clicking and I've checked all the capacitors and all look good.

What else could it be ?

Bcnu2day  “tested the fuse and it was reading 60 volts my cord was reading 122 “ let us know where on the board you got 60V. Since your standby light is flashing you need to check between the power board and the main board. Measure the voltages on the connector from the power board to the main board. Also, check your power button board as well. we need to know what exact model your TV is and try to post some single images of the power and main board.

When you disconnect the wire from the power board to the main board and then turn your TV on, what happens?

No red light shows up and tv doesn't turn on
