No Power In LG 32 Inch LED TV Repaired
As I entered a mini market near the area where I live, the owner of the market who is also a friend of mine asked me if I can repair his 32 inches LED TV that was dead after a power shut down in the area? I put the TV in the back seat of my car and took the next day to my shop for further inspection.
The standby light was on but the TV was not coming on which is an
indication of a power supply issue and that is where I headed right after I took the back cover off.
That TV was sitting in the shop for almost ten years; look closely to the amount of dirt accumulated inside this TV set.
I cleaned all the dust and I am sure you can see the difference between the two photos.
The fuse was intact and everything looked fine except the two bulged capacitors in the output area of the power supply.
I took the board off so I can have access to these faulty capacitors and look what I found. Two legs of one faulty capacitor was already de soldered and it was still attached to the board for some reason.
I do not understand what was happening here and I did not bother to ask the customer so I went ahead with the repair.
I took the two faulty capacitors off and replaced them with good ones and powered on the TV set and it worked just fine.
One problem I faced when I powered on the TV is the HDMI ports were not working. The TV came on but I was getting no signal display.
I took a look on the HDMI ports on the back of the TV and as I expected there were full of dust and needed some cleaning.
After the cleaning of these two HDMI ports the TV worked like a charm. I tested the TV for about one hour and then I put it in the back seat of my car and took it to the customer who was happy to see his TV up and running.
Mission Accomplished.

If that TV was sitting in the shop for almost ten years no wonder the customer looked surprised when you brought it back to him after all this time. In ten years a lot can happen, like having less customers?

Being a regular English user myself, I was amused by Albert's (humorous) observation about it being "in the shop" for ten years. Thank you for the good laugh!

Nice article Waleed. I think these equipments need protective maintenance now and again. Those capacitors got bulged because of long use.
