Wrong Image Size If you are using VGA mode, make sure that the H-Position and V-Position in the OSD is set correctly. Screen Noise When your LCD TV's digital capabilities exceed a digital broadcast signal, the signal is up-converted (increased) to match your LCD TV's display capabilities. Up-converting can cause noise or trash. Dim Screen Video display devices experience degradation of brightness over the life of the device. Normal brightness degradation is not covered by your warranty. Pixel Problems Your LCD TV is manufactured using an extremely high level of precision technology. However, sometimes some pixels of your LCD TV may not display correctly. Pixel defects within industry specifications are inherent to this type of product and do not constitute a defective product. Remote Control Not Working Make sure that the batteries are inserted correctly. Make sure the remote control sensor window is not under strong lighting.
