Servicing GE Atlinks Cordless Phone Base Unit
This base unit with the cordless phone was brought by my brother from Chennai, with the complaint that it was not getting charged.
After opening and cleaning the inside, I noticed that one capacitor was bulgy.
There were rust formations in switches too. The gum on the PCB was dried up and looked very dirty and menacing!
Cleaned it thoroughly and replaced all the electrolytic capacitors. Set worked fine when connected to the DC power supply and further checked it up connecting it to telephone land line, after charging the phone for some time.
It worked very well. Checked both dialing and incoming calls. It was perfect.
So, assembled it back, fixed the broken antenna back to its place and gave it to him. It is common to get such easy fixes a few times, just to keep us amused!
Nevertheless satisfaction list grew further!

Good job of course, but I guess you didn't just use just plain alcohol to clean the board thoroughly with? As it is an important part of this repair it is always nice to know with what you were able to restore the condition of the board with the leaked contents of the e-caps and its menacing gooey

I use Lab Spirit to clean the PCB thoroughly. This is available as PCB Cleaner in the shops. If the sticky substance is so stubborn, I scrape it off with a sharp knife, taking care not to cut or damage the PCB or components.

Well done Parasuraman, leaking capacitors can certainly make a mess on pcbs.
