I received a call from a client who wanted his television checked by a technician.
It was within the estate, so
using the direction he gave I was able to locate the place effortlessly.
I was visiting a client, who wanted her television checked by a technician; she has left a message to her neighbor who has a shop on the same block to direct me to her house.
Once I reached the shop, I introduced myself and my
mission there, while talking to the lady another client of mine whom I have
repaired his television previously passed
by and as we greeted each he mentioned that I really helped him to revive his
dead television.
The shop owner heard the conversation and was interested
to see if I can revive her television which was hit by power surge and decided
to keep it in the store.
I proceeded to my mission and while coming back I found the
lady has already picked the television from the store waiting for me.
I opened the television and since it was hit by power
surge I was much interested on the power supply which always super heavy
casualties once hit by power surge.
First I checked the state of the main capacitor and found
its top part lightly swollen.
With this I concluded indeed this was power surge, sorry I
did not take a photo before removal from the board.
I received this microwave from my neighbor who wanted it checked by a technician.
The owner told me that there was a loud bang and since that time they set it aside (store) and were planning to buy another one since they considered the issue as beyond repair.
I took it with me to my shop and once I applied the power I noted it was powering on well, I placed a glass full of water and hit express button and after 30 seconds I checked the water and found it was still cold.
I then decided to open up the machine and do some troubleshooting.
I received this machine from my neighbor who wanted it checked by a technician.
The complaints was machine has no response from
the inputs keys, Non was working.
I was sitting in my shop working when I heard a loud bang and then power in my shop went off.
I went outside and noted some people near my shop
pointing where the bang came from, Power transformer has blown.
Being a weekend the power was not restored until
Monday, coming back to my shop I passed by a shop nearby and the shopkeeper told me the power was restored back but most of his
items were dead.
Among them was power supply for his kerosene pump, I
went to my shop and did some testing, luckily only my laptop was plugged to
power outlet by the time of power purge.
I checked it out and noted it was dead as dodo, that
a story for another day.
A few minutes later I received a phone call from my
landlord, complaints was that his TV has not worked since the day of the power
surge.
Being month end and I had to pay bills including
rent, I decided to treat this as urgent, I went to his house, picked up the
television and brought it to the workshop for repairs.
Upon opening the television I went straight to the
safety components starting with the main fuse which as you can below it was
open.
I received this woofer from a customer who wanted it checked by a technician.
He hinted that the woofer was from another technician who was not able to repair it.
Items from other technician are tricky to repair especially if the tech had limited knowledge on how circuit works, they ends up making so much experiments and guess works and therefore chances of repair is quite low.
Nonetheless I decided to have a try and see if I can help this customer who seemed desperate to see his machine back to normal status.
After opening the set I found the main filter capacitor rated 470uF/25V has its top part swollen.
From the symptoms at hand the failure of this capacitor fits so well and I was very confident this was one of the easy fix.
I pulled a replacement capacitor from my capacitor kit quickly and decided to do test and the machine came up beautifully.
I received this woofer from a client who wanted it
checked by a technician.
According to her the woofer no base but the rest
is working well.
I did the test to confirm what she said and noted the
woofer symptoms were different from what she gave. The actual symptom was low
audio output.
