So I decided to try my hand today at soldering.
I have this Panasonic cordless phone that runs on a weird 5.5V DC voltage and comes with a strange jack. In the morning I tried the phone with a Sony 5V (actual voltage on multimeter was 5.2V) SMPS DC adapter after cutting the wire and then connecting the Panasonic jack. I had just braided the wires together. The phone worked fine all morning.
Satisfied after running it for a few hours, I decided to solder the joints. Admittedly , it was an amateurish job with a couple of blobs of solder deposited on to the joints after tinning the tips. When I checked the output voltage on the jack, it showed 5.2V DC. Exhilarated, I connected the adapter to the phone and to my shock and disappointment, the phone wouldn't power up!
I then tried to go back to what I did in the morning. I removed the section containing the solder joint and braided the ends as before. Still the same 5.2V DC, but the phone wouldn't power up!
I have tried this with one more adapter and I can't for the life in me figure out what is going wrong. I have checked the polarity of the DC voltage and there is no change when I braid or solder.
Could it be that the soldering process itself is somehow damaging the adapter? In that case, how come it still shows 5.2V DC?
Please someone help me before I go completely nuts! Thanks!
