Hi Scouse

We'll need to know board numbers from inside please.  Maybe we can identify better that way.

Regards
Michelle

You need to start by reading the Voltage O/P's from the Power Supply.  You should have a 3.3v stby / 5stby / 3.3v switched / 5v switched / 12v switched/ 33v switched/ 24 v inverter.

You will also have backlight ON voltages on the  Inverter plug, from memory around 3v.

Let me know how you get on.

Regards
Michelle

Thnks for that will give it a go, when I checked first off there seemed to be no voltage coming off the board. Is there any diagrams to this board (17PW16-2) as this would make life s much easier. Michelle I see you come from Ohms Supply. Do you do a check and repair service on these boards and if so how much also what is the difference between 17PW15 and 17PW16 as I have a working one of these, Thanks.
