Horizontal lines Hi...good picture but horizontal (green) flickering lines. any ideas?

try changing picture size

flickering as the picture becomes smaller and bigger or are there lines showing up? Please describe it better if you can so I know exactly what you are seeing. Any color changes?

Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size.

separate wiring. touching wires creates cross-talk of signals.

unfortunately your tv will require an expensive repair, digital and analog boards and possibly the dmd board. Julio [email protected]

Absolutely right about the transistor and also check any adjacent resistors to the transformer and to the line output transistor. Good luck.

Hi there

This is normally only one of two things : Cable or Mainboard

The W5000 is quite a new Projector and should still be under warranty.

But try changing the cabling first and if the problem still persists , let BenQ replace the Mainboard.

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.

Just unplug and plug back in. Worked for me.

Try it a few times.

May not work for everyone.
