Hi Djmojoey,

Your question is probably best answered by Sony...in the meanwhile, I found a manual for you to review the troubleshooting.
https://www.sony.co.uk/electronics/support/res/manuals/4138/41385145M.pdf

In addition, the Sony website page states some features that are discontinued as of March 2017. Support for KDL 40Z4500 Downloads Manuals Tutorials and FAQs Sony UK

I hope this helps at least some.

If you do not have experience discharging the tube, PLEASE BE CAREFUL!!!

Calibrate it in the options for the game

Hello,

the problem is from the VGA of your TV. Also, is your TV connected to a cable receiver?

Please let me know so that I can figure out what's causing the problem.

I look forward to your reply.

Bye for now.

This is a screen tab fault and in most cases will require the screen replacing

Is it an LCD or plasma monitor? If it's an LCD, it's possible that one of the fluorescent backlight tubes is bad. In some early ones, this is bonded to the LCD panel so it's not replaceable. Maybe it's under warranty?

The screen does not work properly .Ribbon wire fails.

What is the model number it sounds like pixel problems or board problems. For more info ctechnicians.com
