Panasonic Plasma TV Issue Can't Post

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

here the power supply unit

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 !

Hi

So finally i found an instruction repair but i have only the electrical wiring of thoses boards.

I would like to have the values of each components to test them with an ohmmeter im saying that because i would like to check all "RF1501" on SS board. Looks like they are voltage regulators they are probably out because of over heating...

Thanks
