Question about HP LC3040N 30 in. HD-Ready LCD Television

1 Answer

Screen goes bright after 1 hour of use

After an hour after turning on the LCD TV, it goes very bright, and the picture is not viewable. I turn off the TV, and turn it back on, and it's fine again for more than an hour before it does it again. Also the remote is not working. Put new batteries in, but to no avail. But it works occasionally when it wants to.

Re: screen goes bright after 1 hour of use

I have the same problem when switching component inputs. I also had a problem with the backlight going off after 10secs-5mins. Which is still being resolved.

LCD TV Picture

I've seen some of these where some of the cable connectors inside of the set need to be reseated . They have become loose . Or you may have a problem in the video circuit of the set . Good luck
