Overcoming Trouble Vertical amp & Linearity
This time I share experience of repair Alexander 21" Sharp Tv with less linear vertical problems. The case is the image widened partly, after I adjust but did not work. After checking there Resistor that its value changed over, after the replacement and in the Adjust TV picture can return to normal. Damage Vertical Amp & Linearity usually caused by the size of components that have changed so if the adjust does not work can be checked R503, R513, R514, R520, C515. for reference can be seen schematic above.
