Question about Olevia LT42HVi 42 in. LCD Television
After about 45 minutes flickering horizontal white lines appear on screen. Switching off for a few minutes the picture is normal again for a short time, then problem re-occurs. Sound is OK. Any ideas please?
It would seem that the video processing section is sensitive to heat. You do not indicate how old the set is, so if under a year, it should still be under warranty and you should request warranty service. Provide as many details about when the problem occurs so that it can be reproduced.
If the unit is out of warranty, check to be sure that any fans on the top or botton are free from dust and are turning. Also, you can open up the back and carefully reseat all of the cables and connectors. A bad connection at one of those could show up like this too. If all of that fails to resolve the problem, then the unit will need to be seen by a servicer. There are no user servicable parts inside other than the actual boards and those are not cheap. It is possible that a servicer may spot something that we can not see, being remote and all..
Good luck and keep us posted.
