Their may be a problem with the backlight or the invertor supplying the backlight with its energy I have seen this many times and it looks rather like them cartoons running too slow as you say strobing,this is the backlight flickering

Unfortunately (unless its bad earthing on the invertor) this is in my experience the backlight itself and isnt economic to repair however it would be good pratice to have the invertor replaced before condemning the backlight


Let me know if you need more info


Hope this helps

Expert:  Anthony_Infotech replied 7 years ago.


The problem with Matsui is that its a brand name used by Currys or Dixons or Comet,(cant remember which)and isnt a manufacturers name so the parts are not easily traceable, the sets usually made to order in China or Turkey sometimes by a company called Orion

If you get me all the information off the set that includes model and serial number and anything else on any label you can see I will try and trace the invertor, but bear in mind you could have a backlight problem, this isnt a repairable option the backlight being part of the actual display itself


Many Thanks
