When you say all boards you mean the t-con and power supply circuit ?

What do you see on the screen at this point ?

Anything ?

Customer: replied 10 months ago.
power supply board, t-con board, both converter boards, nothing on screen, just green power light that blinks about every 10 15 seconds
Expert:  Jack replied 10 months ago.

Is the screen just blank with some background light or completely dark like when the tv is off ?

Expert:  Jack replied 10 months ago.

In any case , did any of those boards make any difference whatsoever since the original problem ?

Where did you get those boards ?
