Panasonic Plasma TV Issue

Hi there ! Well i have a problem with a plasma tv model TX-PF50X20 i think its a model mainly sold in europe because i couldn't find more infos on US Forums. But it doesnt matter for the simple reason that the chassis might be shared with other panasonic tvs So anyway i got that tv from a friend it wasn't working, so i plugged it and when i tried to turn it on. I had 7 blink code, i took out the back cover i found that something unplugged so the tv was already openned before me. I tried to power it on again then i had the 10 blink code ! Considering im a car mechanic i did some continuity tests on the power board theres nothing special ! there is no puffy capacitors. On a french forum someone told me that issue might from the SC board and he can send it to me for 160$ but this perso doesnt want to tell me how the check that SC board ( he may be afraid that if i found the problem i'll fix it my self ) i want to do a good diagnosis before spend any money in it ! here the back of the TV https://www.hostingpics.net/viewer.php?id=152486teleplasma.jpg here the power supply unit https://www.hostingpics.net/viewer.php?id=896043carte.jpg What do you people think about theses transformers in yellow ? Look like one is in bad shape ! I read on some forums that there is a thermal fuse in these coil packs where are the good point to control with the ohmmeter to check them? any one can tell me how theses tvs works ? Sorry for my bad english.. Thank you !
