I have a Samsung Hlr5667wax/xaa DLP TV and the screen has gone green/green plaid pattern.


when the color wheel stops the picture will be all over the place. and you will have lines when it starts to fail as its not going fast enough for the picture. wining sound is it wearing out.

I have a 32af41. Green horizontal retrace lines show up on screen then it faint at first then more and more apparent then it flashes green and turns off. I can only turn it back on by unplugging the tv...


These are caused by the ageing of the tube and the final video transistor for the green cathode - the cutout voltage on the final video board is no longer doing its job as the tube heats up so the current passing thru the tube goes up until the X-Ray protection kicks in and cuts the power completely.
Resolder all the components on the video board and try to readjust the cutout voltage - there's a semiadjustable resistor on the video board, right next to the video power transistor - this will give you a few more months of use.

Green lines


Due to vertical section failure horizontal line apprears. You did not mention about picture. Green horizontal line means with picture or without picture. With picture means there is some leakage. Without picture only singe horizontal line means vertical section totally not working. Particularly green horizontal line means maybe leads to jungle ic failure. Please mention your simptom clearly what you get and what you will not get both video and audio. It will be helpful to answer. Based on your question this is my small information.

Green lines on my Sony projection


Those are called retrace lines and they are the result of the blanking pulse not having the desired effect. This could denote a problem in the Horizontal section of the TV. In this case the green gun is not being turned off as it goes back to the left side of the screen.
