Good,

did the backer that came with the kit say anything about U4?

scooby-doo:
No mate I cant say I remeber seeing anything about U4, I didnt change U4 from the board that I got from Flebay. Andf I am getting exactly the same fault

Just to add that if I turn the board back over and check the voltages from the 10pin connector to the right at the bottom of the board this is the readings I get

GND=0v
5VM=0v
GND=0v
5v=0v
GND=0v
12v=0v
-12v=0v
GND=0v
5vs=5.10v
STB=1.8v

Ohm Supplies:
If you have 5v from the point I gave then the orignal fault of a blown 5v supply and the tx problem is solved. If the opto (information is on the backer) was the wrong way round them 15v has gone down the 5v line and onto the scaler board,  it depends on what its damaged its done however it doesn't always damage the board enough to make it B.E.R. but sometimes the front button set won't work,

Did you get the board from fea-bay or the whole set?

scooby-doo:
Hi Andy
I have the original board and the board I have from flebay.

After I screwed up the original board I removed some of the new parts and fitted them to the flebay board, this did not include changing U4 so the flebay board has still got the original U4 in it as I thought I might of blown this too by putting it in the wrong way round in the original board

Do you think I should change U4 on the flebay board, and can I interchange it with either U5, U7 off the original board.

Ohm Supplies:
Getting a bit confused now,

Has a psu been in the set and switched on with the opto the wrong way round?
