Re: Panasonic TH-42PZ77U SC board repair 7 blinks
Hi everyone.
Apologies for resurrecting this thread.
After several months, I decided to fix my SC board by replacing the needed FET's...she's alive!!!
Now the only problem I'm having is finding the most up to date firmware so that I can update my TV.
Can someone please point me in that direction or can someone email the file? I'll PM you my email address.
Cheers!

Hi everyone.
Any thoughts on the above? I would appreciate your feedback on which of these FET's appear to be gone, so that I can place an order.

Re: Panasonic TH-42PZ77U SC board repair 7 blinks
Ok, just completed a diode test with legs in test right leg and left leg.
Row Q641 to Q645 : RL = 043 LL = 764
Row Q695 to Q696 : RL = 495 LL = 1.460
Other side
Row Q648 to Q654 : RL = 477 LL = 1.306
Row Q622 to Q626 : RL = 393 LL = 1.386
Q601 : RL = 541 LL = 2.748
Based on these readings is it safe to assume that Row Q641 to Q645 are the bad FETs?
Your feedback is appreciated.

Now to find someone in Canada (GTA area) who sells these FET's (B1DFKM000002).
Anyone know where to order these online? I've only been able to find someone in Spain / France who are selling these online.

Hi everyone.
First time poster here.
I too have a Panasonic TH-42Z77U that has give me the 7 blinks. The TV is around 9 years old.
I have followed online and have also confirmed that the SC board is the issue.
Question regarding the FET's that you have tested... Is it necessary to have the one FET leg up, or can I test it with it still soldered in?
Apologies if this is a dumb question, but this is the first time that I've used a dmm... I'm...Leave a comment:
