I have one of these power suppliers as well but it's seems to be making the picture go out of sync. Im not sure if it is the PSU but I have replaced all the electrolytic capacitors with no effect change.
Can anyone let me know if this is a stranded problem and how to fix it.
Thanks

Maybe best to start a new thread include your model number etc and add a picture of the back of the tv showing how all the boards are connected and a picture of each board thats used in your set please make them as clear as possible as we go of the information/pictures you provide.
