PSU repair for Maxim 1154 / BUSH IDLCD27TV006 GOODMANS IDLCD27TV006 / INO3

[pacmyc]

I've got a LCD TV, from another manufacturer but the PSU is the same as in the TV´s listed in the subject.
Well, main fuse once blow, TV went dead, and when replacing the fuse it just blows again and again.

After som looking around on the internet i replaced the FSD200 as well as a lot of other components such as capacitors and some zener diods and transistors;
IC21, D325, D326, Q300, Q301, Q302, D315, D318, C322, C356, C213, C330, F300

I´ve now got the TV running, but, it´s a hell to turn it on. I have to turn on/off the main power switch for a few times and than it comes on, but 4 times out of 5 with no sound, or with some kind of strange disorted noise.
If I now leave the TV on for 10 minutes without the sound, and then turn it off (with remote) and turn it on again, the sound normally works...

It´s so strange that the TV sometimes works and sometimes not.
There´s  no bad contact or anything on the psu, i´ve checked it very carefully.

Could it be the opto IC37 ?? I have ordered it,,
or do you have any other suggestions what else could cause this strange fault?

Or might it be the IC30 (ICE1QS01) ?

I would be greatly thankful for any tips or ideas you could provide me,
