For some time now I rarely write a blog just to fill my free time, because is a lot of work I have to finish. This time I wanted to share my experience some time ago while fixing a TV SHARP PICCOLO elbow trouble. When it's my neighbor came to me told me to check his dead tv. Did not wait long before I came to his house, after checking it is true tv sharp piccolo brand 21 "flat, only red lights without images. Later in unloading and my tv found the engine is still very new, there are no suspicious damaged. The first step I check the horizontal transistor, it turns transistor is not dead. My next step measuring voltage, it turns out the B + voltage is increased to 150V, which should be 110-113v. I began to suspect and checked against regulatorpun series began. After the replacement of some of the areas regulators elco finished, I turn on the tv again. and found his condition remains the same. Ic regulators began to think I was wrong. Then I try to replace the ic regulators. and after replacement of the regulator ic, but the result remains the same. Then I try way way to the cafe to find a reference how to resolve these tv. and the results have not been up as I want. Every other day I was working on tv again, any search I did with very thorough and careful. I checked one by one active and passive components around the horizontal circuit, because I think it's like a load behind. See also the mother of his illness finally turns 333/400v mylar capacitor for short horizontal line is measured with X1K. After replacing the component with a normal tv flame. After doing all day burning tv no problem anymore. and live longer wait paid ya ... thank God.
