Question about LG RU-44SZ51D 44" Rear Projection HDTV-Ready Television

2 Answers

RGB-PC input problem?

Hi, I have a LG DLP RU-44SZ51D tv that is a couple years old, and I want to hook up my laptop to my tv. I have a 6-month-old HP Pavillion dv6000. I bought at Bestbuy a VGA cable, and when I hook everything up, I hear the cable audio, but there is no picture or audio from my laptop. Also, someone told me all I need is an S-video cable, but the same thing happens as with the VGa cable. Any help would be greatly appreciated. Thanks!

I had the same problem and the fix for me came from updating the driver for my video card which you can get from the manufacturers website

Rear projection lg lcd 44 inch


Is it an LCD or DLP? The Model below suggests it is an DLP. Sounds as if you have the dreaded light tunnel collapse common to all LG DLP TV's. Inside the light engine there is a square tube made up of four mirrors. These mirrors deform and crack with the heat of the lamp. They fall down over the light aperture and cause a shadow of varying degrees. It is fixable now at a realistic price ( used to have to replace engine) as LG have made the parts available. It would take a competent tech around three hours to complete or if you are technically minded you could do it yourself. I hope this helps. Good Luck.
