Question about Televison & Video
I have an R52WH74 RCA projection 52" HDTV. Turns on just great then in about 10 to 15 mins, the picture goes out but the sounds stays on, please help.
That's one of the common symptoms, may run 5min to a few hours then no picture but sound stays on then back on in 45-60 seconds. lamps are easy to change but, and i cannot stress this enough DO NOT GET A GENERIC LAMP!!!! use only the original lamp, the cheap knockoff lamps are all over the internet & they are junk - when the factory (sylvania or osram) build the lamps they are tested and graded, the "A" grade lamps are sold as OEM parts but the poor quality parts (that failed inspection) are sold to other companys who repackage them then sell "SAME AS NEW" - 99% will fail within 2 weeks.

it might be either a problem with the lamp or the lamp overheating. how old is the set how many hours do you suspect you have used the lamp for? might be time for a replacement.
some people have reported success in cleaning the tv from dust it improved the airflow so it might be a overheating issue or lamp failing. if its not a lamp issue it will require a professional inspection. the issue maybe in the power board, can't say over the internet.
