Yes that sounds about right now.. but did you replace the Inverter board as well... I mean did you replace everything including all electronics attached too? Or just the LCD, see it may be the driver?

It could be your LCD inverter is going bad. CLICK HERE to see. It is relatively easy to replace. Remove the LCD screen bezel screws and gently lift away close to the bottom. The inverter is on the bottom right under the LCD itself. Usually 2 screws to remove and unplug then replace. If it is not the inverter then it is your LCD backlight in which case you will need to replace the screen.

My CF-51 monitor goes off intermittantly. When I switch to an external monitor, it will toggle on and off for awhile then shut off again. It hasn't worked at all for 2 weeks then yesterday it worked all...

Hope this helps! If so please give a rating!

Screen has lines in it after its warmed up, color fades


take apart the screen housing and
replace the LCD panel. It can be done with basic hand tools and a little patience. 12.1" "bare-bones" CF27s should be REAL cheap on ebay, the 13.3" ones might be a little more. or you can send it in to panasonic for replacement.
