Good afternoon, could you give me a hand to repair a 21 'matsui TV with drama in the vertical zone ... When turning on a white line appears in the middle, from the middle down all black, from the middle up the image comes out half with rain and flickering, when turning on 2 seconds later it turns off again, but after 4 attempts it stays on but with the drama that I comment above. the brand and model would be matsui of 21 'model MT-TV2134

Hello Friend. solved the pins of the ic. vertical and change the filters that are related to the ic.vert. and change even if the diode that feeds the ic is good. vertical and measure the tension on each pin of the ic. vert. and you upload results. and if after the indicated failure persists you can try another eprom. new that is of the same number and recorded with the data of the micro jungle. regards
