Yes. There is no vertical deflection. The circuit that controls vertical deflection is bad. This is an easy fix for a TV tech. Take it to the TV repair shop.

I had a similar problem on a different monitor and fixed the green sparkles by selecting a lower refresh rate.

Once you have stripes or lines in the screen then the only solution is to get the screen replaced but that would cost just as much or even more then getting a whole new monitor.

Hi

Please try the following
Load into safe mode

Click on

Start>Control Panel>System>Hardware>Device manager

In device manager click on the litlle plus key next to Display adapters and see if there is a yellow excalamtion mark in there. if there is then you will need to reinstall you graphics card (vga card) drivers, if not right click on that option and click on uninstall it will then ask you to restart click on yes and hopefully this should solve the issue

Please can i ask that you leave feedback and vote if this has been useful

This is a known symptom of a failed power supply board. Here is a repair guide for this unit that shows how to dis-assemble the unit and then what to look for and replace to rebuilt the power supply board and bring the monitor back to life.
