A client home theater displayed “push power protection” error on its display board and figured out that this could be a small issue and can be sorted out by himself.
So he decided to ask google and when he did the search for the error google referred him here.
After going through the article he noted the writer of the article is from Kenya and being also a Kenyan decided to call me to help him out on this funny error.
When I received his call he told me that he is from Nairobi and wanted to know which part of Nairobi I come from so that we can link up.
I told him our shop is in Utawala and to his surprise he was also from Utawala, a walking distance from my shop.
I booked him the appointment and came the following Saturday after work since he works around the area (Jomo Kenyatta international Airport).
After receiving him in my shop we did a little introduction and work begins.
First was to confirm what the customer said and therefore I plugged the machine to the power socket and pressed power on button and this is what I saw.

I got a phone call from a client who wanted his television checked by a technician, it was a referral case from another client I had repaired his gadget previously.
He directed me to his place within the neighborhood and was able to trace his place. After sanitizing my hands, I was ushered in and shown the television.
I asked for brief history and was told they shut it down previous evening and in the morning the television never wake up.
I applied the power to confirm what they said and indeed there was no sign of life even the standby light was absent.
With that I took the television to my workshop and after opening it I went straight to check the state of the safety components beginning with the main fuse and to my surprise noted it has a thick jumper wire across it and this lead me to conclude the television had a previous repair.
