nightspirit Posted February 18, 2011 Report Share Posted February 18, 2011 Hi. I have a Sony Trinitron KV-XA21N93, it has scanning lines from top to bottom. I already have replaced possible defective capacitors that has 160v and 250v but still not able to fix it. I have checked for possible open resistors but did not find anything.Can someone help me out? Quote Link to comment Share on other sites More sharing options...
audioguru Posted February 18, 2011 Report Share Posted February 18, 2011 A TV is supposed to have scanning lines. They draw the picture.Maybe you mean that the retrace lines are visible.The retrace occurs when the beam is supposed to be turned off so it can return to the left side or to the top where it can be turned on to make the next scanning line.
