Hello,
If the stand-by 5V supply is fluctuating, this is worth a check, before replacing the complete power-suppy.
It's normally a separate supply to the main, using a small transformer to supply the 5V.
Check the normal electrolytics, etc.
Regards
John

Thanks for your replys everyone
*I dont have a small transformer to supply the 5V - the electrolytics all looks fine to me
* I will get pic's done later on tonight for you
* Had a look for the board and it is expensive = £89 / 144.620$US and thats abit high for me at the moment
Motsey:
Sorry for the late reply here are some pictures of the main power board - let me know if they are ok or if you would like me to take more, if so which bit and whats best way of doing it eg Zoomed in close up.
Hope someone can work out what I could do/try to get this board working - Im up for trying almost anything.
-Thanks
Motsey:
more pics but this time zoomed in so there are 3 pics which were taken kind of side by side - they might need piecing together but i didnt want to attempt incase i ruined the quality.
-Thanks
Motsey:
Are thesepictures ok or would you like me to take others?
