I got a phone call from a client who wanted his machine checked by a technician.
He told me that he just googled technician nearby and my name popped up.
I asked him the nature of the problem and item to be checked, He said he suspect power surge since the home theater and microwave are dead.
I asked for the model of the home theater so that I can prepare myself in advance.
The machine model was the Sony HBD-DZ950, I logged on the net looking for the service manual of this machine so that I can be able to figure out the most likely culprits and value.
I was lucky to get the manual and went straight to the power supply section and was able to pick out the possible culprit which normally fail if there is power surge.
I picked the components from my store and headed to the client site which was around 20Km from my place, using the pin location provided, I was able to locate the place effortlessly.
I was ushered in and shown the machine, after opening it I could see the damage done by the power surge without even pulling the meter.
