Question about Flat Panel Televisions
When the TV signal (HD cable with set-top box) begins, or when DVD is played, there is a red "rash" across part of the screen. Although the "rash" is generally in the same are, it is not always the same size, and, sometimes, the "rash" is blue, or blue and red. Regardless, the "rash" is mainly noticeable in black areas. There is no "rash" b/f the cable box or DVD is turned on. Dying plasma? Hot pixels? Bad signal? TIA for any help. Mike Intermittenly, Red Pixels will flash on the screen, mostly center 1/3 of screen, in the black shaded area of the picture. Only with input from the cable box, not playing a DVD.
i'm having the same problems, in the dark areas i get a red shade. has lg or anyone else figured out how to fix it, if so your help would be appreciated very much. also i have my pc connected to it and having the same problems.
