LG 14 inch CRT television model CF-14D10K sound okay no picture.

A friend of mine called me to pass by his place to check on his television, the complain was no picture but audio is okay.

I passed by his place and he was out of the house and I was attended by the wife. There was no power in the area and after asking her a few question about the nature of the problem she confirmed what the husband said.

I never carried with me any equipment because I was not intending to do the repair on site.So I took the television with me back to my workshop, I applied the power and to my surprise the screen was full.

LG 21 Inch Television with shutdown symptom

 A customer came to my shop and wanted his TV checked by a technician; he didn’t come with the TV so I had to accompany him to his house which was a stone throw from my workshop.
Upon reaching his house I found the TV was already open, he was trying to fix it by himself and being a soldier I think he assumed the by fact that his TV refused to work was a criminal act and therefore he wanted to do some investigation.

Samsung DVD player Model DVD-D530 hit by high voltage

A friend of mine called me to pass by his place to check on his DVD player which he suspected was hit by high voltage.

I passed by his place and the DVD was brought to me, I opened it and my first stop was the power supply since power surge usually affect the power supply especially the primary side.

The good thing with power surge problems are usually catastrophic and therefore in most cases you can easily identify the problem without using expensive test equipment and therefore your eyes are good enough to locate the faulty component(s).

DVD power supply dead now repaired.

Hello Humphrey! Your book on DVD player repair guide has made me to learn new hints how to solve problems related to DVD switch mode power supply (S.M.P.S).

Now I received a DVD from my friend which had power problem .When I opened the casing I noticed the fuse 2A/250V was dark inside. I removed it and connected a 100W bulb across the fuse and it was too bright and no voltage across the main capacitor 10uf/400v.

HOT transistor is continuously getting shorted after replacement



For those who have been in repair business for a while you will agree with me that this is a common phenomenon.

You receive a TV in your shop and you diagnose the problem and found the HOT is shorted and you begin to celebrate how you got the culprit effortlessly.

You pull a new HOT transistor and replaced it and powering on the TV came up beautifully and before picking the phone to call the owner to collect his machine you realized that the TV is down again.

You check again and find the HOT is shorted again. If you have never experienced such a problem lucky you, but for Abdul Haleem from Sri Lanka has not been lucky... Lets us hear his story.
