BR is usually tested using resistance or diode checker. Examples on Youtube
One is here http://www.youtube.com/watch?v=dqkT6...ayer_embedded#!

If you were voltage checking across end pins , on this shaped BR this is usually the DC Output the AC in is usually the middle two.

If you use the ohms checker ( Power OFF) it is unlikely it will be no reading (as in Video)
as in circuit the result is affected by other components, however you should see a notable difference in the readings when you swap leads over.
If you post the results someone will advise if they are ok.

Hi, can anyone point me on the road to finding this fault, as stated I am a newbee and understanding the route of the electronics is apparently hard for me if I am not getting the value at the output to the main board how do I check track to find where it stops. Thanks again for any assistance

We are all trying to help you but you are not helping yourself. You keep jumping from one thing to another - changing to a non matching board then swapping components about means we have no idea what you have done or if any more damage has been caused.
You need to get back to the point where you had a power board that provided the steady 5 VOLTs at the connector and post a GREAT picture of the back of the board so we can look for damage.
You need to answer our questions - you have posted since I asked you to test the bridge rectifier but you have not said if you have done the test or posted the results. - You may have lost the interest of those helping in the original posts or even annoyed them - starting a new post saying the person you were in contact with had been some time?
Most of the members have jobs,college, families and life which impacts on this totally free unpaid service which they provide, and they are not always available. If the thread is structured and easy to follow others will pick it up and try and help but if it is a mess they will just move on to another thread.

My understanding is that following the initial 5v from the power board to the main board a signal voltage comes back from the main board to turn on the rest of the voltages to the connector.

As the original damage was to the Scart a fuse may have blown on the main board
but we need GREAT pictures of both sides of the main board to stand a chance.
