Re: TNPA5105 rebuild

Hi Tw2005. Thank you - yes, my first rebuild. I did some small PCB prototyping but nothing the scale of those boards, not even close. Learned some new skills with desoldering and soldering those small "flea components" like IC920 without hot air station :-P.

I think you are exactly right regarding those subs. The parts could be easily replaced, had the Panasonic actually publish their parameters. I think the secrecy is deliberate, as it is good for business ;-). I mostly got the idea about the specs roaming through the threads on this...

Re: TNPA5105 rebuild

Hi all. This is my first message on the forum. First of all, let me thank you guys for useful advice, especially in TNPA5081 rebuild thread (my broken SC board was TNPA5105, so I write it into this thread). It helped me a lot and I also want to share my "repair story", perhaps it can help others too.

So, a week ago, my Panasonic TX-P50U20E suddenly went dead with a silent *pop*, giving me the 10 blink code afterwards. After looking at the manual, I thought - P board. Disassembled, no obvious signs of damage anywhere. But found dead short...
