TP-Link wireless access point repaired. Model: TL-WA501G
A few weeks ago, my family and I moved from one house to another. We were moving our stuff from the old house to our new rented house. I tried to power on this device to get wireless internet in the house, it did not power up.
This device runs on 9 volt power transformer and when I checked it with the voltmeter, it gave me 12 volts reading which an indication of a good working power transformer. The power light was off and seems like the device was completely dead.
The moment I took the cover off, I headed directly to the main fuse and the four diodes on that board. I was not really shocked to see that the one main fuse was open. FB1 was open and FB2 was not.
I could just replace that fuse and try it again but I wanted to know first why the fuse was open. Usually when fuse was open, there is something wrong with the diode bridge rectifier. In my case there were four diodes and when I checked them with the meter, two of them were shorted out.
I replaced the four diodes. Here is a good advice to take into account. When there are two diodes shorted out and the others are not, it is better to replace all of them. I wanted to power up the device but again, I wanted to make sure that everything on that board is working fine. I put a 100 watt light bulb to the main fuse. In this case it was fuse marked FB1 and powered up the device, the power light and the other lights on this device came on indicating a good working internet access point device.
I replaced the FB1 fuse with another one and powered up the device. All was working fine and I could see a good signal on my laptop.
Later on, my wife and I decided to buy a new one. I bought a two in one device; access point and router. So I sold this one and bought the new device.
So, my wife and I were happy and the customer who bought the access point was happy because he bought for a cheap price. Mission accomplished.
