Degrading Solder? (Pics)

Post by iHeartNuance »

Hello,

Regarding a UN60H7150...

I'm just wondering if the soldering in the attached photos is normal.


I have picture and sound but the unit will only respond to input from remote or joystick during the 30 seconds or so after startup. USB media playback also glitchy. Naturally, I want to fix it.

Was gonna replace main board - noticed this when retrieving the S/N.

Just noticed....the third pin from the left looks like it no longer contacts its wire!


Many thanks in advance for any input.

I think there is no issues with the solder, it is a transformer it's normally to looks ugly. But why not to resolder them. Most of the issues with switch power supplies are coming for old capacitors, you can try to replace all of uF capacitors from the live side. Resoldering of most of the elements it can help as well.

Thank you, bobiturboto, that's exactly what I did.

Applied some Vaseline then a bit of Wal·Mart solder to each connection.

It looks even uglier now but the unit appears to be 100% fixed!
