ARMCO Microwave oven came in dead now repaired!

I received this microwave from a client who wanted it checked by a technician.

Initial test indicated the machine was totally dead, I opened it and tested the power supply fuse and found it okay.

Next, I checked the control panel and found inductor L101 was open, I followed that line and noted it was feeding IC100(NK364PN) and therefore suspected it could be shorted.

LG HOME THEATER MODEL DH3140S COME DEAD NOW REPAIRED.

I received this home theater from a client who wanted it checked by a tech, I applied the power and noted there was no sign of life. 

I opened up the machine and proceeded to scan the whole system, beginning with the power board and later motherboard.

I noted two capacitors with top part slightly swollen on the power supply section, usually if you get a capacitor with top part swollen it is advisable to replace it directly with testing.

32 inch Vitron Television picture upside down after motherboard replacement now fixed

I received this television from a customer who wanted it checked by a technician.

She told me that she suspect a loose cable and hence minor problem.

I checked the voltage and found they are present even on the secondary side of the power supply.

I also noted some components were getting too hot on the secondary side (Never torch components on the primary side unless if you power off and remove the power cable from the outlet) and since the power On led was off means the microprocessor was also not getting power.

I decided to do new motherboard replacement, getting these boards in my market is quite easy.

I visited the shop and I was back with one which was exactly the same and therefore I expected easy fix, plug and play.

And yes the television fired on beautifully from the back I could see backlights are on.

Turning to the screen I noted the picture/image were upside down like you can see below.

21 Inch CRT Sanyo Television (model CM21YS2S) came in dead now repaired

 I received this television from a customer who wanted it checked.

CRT television are getting phased out here in Kenya very fast but still am getting a few from customers like the one before us.

I asked the customer a brief history of the problem even before opening.

He told me that it started to take time to power up, 1 hour, 2 hours, 3 hours 9 hours, one day and eventually never powered again.

With that I concluded the problem is capacitor related and therefore when I opened it I first did scanning the whole board and noted one capacitor with top part slightly swollen on the vertical circuit.
