I have a Samsung PS-50Q97HDXXEU which has a blank screen.
I have a good look over it and found all the PSU voltages are fine, a FET had failed on the Y Main and the top Y buffer measures 10R.
I removed the top Y buffer and replaced the FET on the Y Main, the Y Main seems to work and the bottom half of the screen has a slight grey which makes me think it is ok.
The million dollar question!, do I just need to replace the top Y buffer or should I see at least the OSD or a picture with the top Y buffer removed?
I am really trying to work out the classic problem if this is worth fixing or not as the top Y buffer may lead to the Y Main which may lead to the bottom Y buffer and then the logic main
The standby light flashes 6 or 7 times at switch on if this means anything.
Thanks for any help.
