Display panel not working - Sony STR-DN1080
I have this receiver which works great - on screen GUI and all channels of audio are carried through, but the front display has stopped working! Confirmed that it's not a dimmer setting issue.
Searching around, it seems like this has happened to a few other people, but not super widespread. Others have mentioned that applying pressure causes the display to come back, but this hasn't worked for me. Tapping it in the right place would bring it back for a second or two for me. Any ideas what could be the cause? Online posts have mentioned vague "corrosion", which I assume to be bad solder joints, but the board looks clean to me (photos attached).

Re: Display panel not working - Sony STR-DN1080
I also see fractured solder joints at the display's filament pins. They are at the ends 2,1 and 54,53. It's not corrosion.
It's best to resolder the whole display because the display is big and doesn't always wave solder well. I'm not sure how the lead-free works with the Kovar pins. |

Re: Display panel not working - Sony STR-DN1080
Wow, sharp eyes! You're right - I resoldered the joints between the display and the board, and it works now. Thanks so much, I've learned that I need to look more closely on some of these solder joints.

Re: Display panel not working - Sony STR-DN1080
Sony still has learnt how to avoid bad/cold solder joints...

Re: Display panel not working - Sony STR-DN1080
Dear all!
I have the exact same problem with my STR-DN1070 receiver from Sony, but it looks identical. I'm sorry, but can someone please highlight which pins I need to resolder? I'm a total noob when it comes to this kind of electronics, but have used a solderingiron quite a lot on finicky electronics in the past, so I just want to give it a shot!  Thank you very much! |
