Re: solder don't stick, new tip.

I had the same situation with my old soldering gun. You have a corrosion tip and there is no way to fix it. Don't use any sandpaper I did it but just making it worse. There is two option. Change tip and buy some cheap tips (if you soldering one time in a month) or purchase a new soldering gun because high temp and bad soldering wire are killers of tips.

-Dont use sanding paper
-Dont use tinner for clean tip
-Use clean water and sponge
-Dont use your tip like aggressive
-Stay all the time some soldering wire on...

Then the flex cable is working properly. But the board still not charge the battery. Some capacitors are extremely tiny and I only have a soldering gun I don't have a heat gun. That's why it's hard to desolder...

I ordered a Bluetooth earbud one and half year ago, and right earbud broke. The light that should have been red when you put it in the charging case started to turn blue continuously(which means earbud is not charging) and after 1 week the earbud completely died. I disassembled right earbud because the warranty finished. I diagnosed the battery was dead, so I charged it with TP4056 and revived the battery.

Right earbud is working now but I still didn't solve charging problem. I checked the charging box with a multimeter. There is 5V. I checked the headphone pins and they are working....

Re: cheap but good thermal paste?

I think there is no price performance thermal paste. Of course I'm not meaning expensive pastes are better but If you will purchase 3-4$ thermal paste these are not giving anything.

Re: Sony Phat PlayStation PS2 power supply repair
