nothing showing? are you trying to test it on ohms? or with tv on and voltage each side of the fuse?

Make sure not to confuse a single "1" on meter with 0.0 ohms.

Means f*** all... you could have got a bad board and that has happened to me MANY times. Sellers just don't test their boards.

Check ohms between Vs and GND, and check all transistors/diodes (mounted on heatsinks.)

I've fitted new y buffer board and still no luck, I have come to the conclusion that it must be that z board, I have disconnected both cables from the y board and the tv gets the chimes but still no pic does that point to the z board?
