Re: Panasonic TH-42PZ77U SC board repair 7 blinks

Thanks tom, so i found the bad fet... tried to remove it, with another soldering iron from a friend. And started to wiggle it a little to get the fet off... unfortunately, the solder didnt melt, but the glue of the board did. With the result that i pulled a piece of the board with the fet.
Now I am going to ask a silly question for some of you, but as you noticed i am pretty new to this...
Is this repairable? or can i throw the board away?...

Thanks tw2005, that post helped me to understand more about a perhaps faulty fet. So i lifted up the legs and found out fet Q552 is bad.

Now Im trying to pry it off, and the two legs where easy, but is it even possible to pry the fet off with a 60W iron? And i know it has been said in this topic before, but heating the tab on de D side didnt get me anywhere in 20 minutes... any tips?

Hi Guys,

I have noticed a lot of troubles with the SC boards around the internet.
I got a 42py70fa (comparable to a 42pz70) which has the same SC board as above. And after reading many topics and forums i chose the easy way out by buying a second hand SC board from an internet shop. However after installing it, and troubleshooting it, it looks like this one is broken as well!!
Really bummed out and not really wanting to spent more money, i am now reading up on replacing the fets. However i have no experience...
