Display Problem In Samsung LCD TV Repaired
I have got a call from one of my clients about his home Internet was not working. The router was not getting the DSL light thus I have to contact the internet service provider. Unfortunately at that time the internet service provider could not provide the solution due to some technical problems. Before I left my client offered me a cup of tea and asked if I have any reference of technical guy that could repair LCD TV.
He said the LCD TV had display problem. I have asked his permission to let me try if I can solve the problem. After he had granted the permission, I removed the TV cover and started on the troubleshooting by doing a visual inspection first.
There were no physical damage or burn marks and each of the circuit boards solder joints seem to be intact.
Now I’m stuck because I did not carry required tools for TV Repair. Suddenly I got an idea why not try clean LVDS cable contacts and see how it goes. Hence I have removed the flat cable and what I found was; there was oxidation on golden contacts hence I have cleaned the contacts by rubbing it using a rubber Eraser.
After the cleaning work, I put everything back and turned the TV “ON”. Guess what? The display problem was gone and there was a smile on the customer face.
