Coloured vertical lines on Aurea LCD-screen

[ronkefe]

I have a Philips Aurea LCD TV (model 37PFL9903H/10), which I bought in April 2009.

A few days ago, vertical lines started to appear on the right hand side of the screen. See the attached pics. The lines come and go, but they're showing up more and more frequently.

The lines appear regardless whether ambilight is switched on or off. The TV software is up-to-date.

I've tried the following to no avail:
- removing the electrical plug from the socket for a while (1 hr);
- resetting the TV to its factory settings.

Any ideas of what the problem could be and, more importantly, how it can be fixed?

I think it will be a defect of lcd or lcd-control. Only a repair can fix the problem.
