Searched some old posts and google, some say 30J124 are Q12 Q13 sus up and some say they are the q21 q22 sus down. If any one has a ebr66607501 board handy and can take a quick look that would be much appreciated. Thanks

The only apparent difference I can see between the 30F124 and 30J124 is the 30F124 is rated at 300v and the 30J124 is rated at 600v. It seems you can replace the 30F124 with a 30J124.

I found this video that shows the location of the two on a similar model TV (perhaps). https://www.youtube.com/watch?v=ozJ-YEWcJTg

Thanks for the info, so to be safe I will replace them all with 30J124.
