Re: 42pfl7422d/37 help
500V was the range. When I connect my laptop to the computer via HDMI my laptop detects the television but I get no sound. When i press the source button on my remote I can tell the TV is cycling through the sources and on one source(not sure which one because no picture) there is alot of muffling coming out of the speakers.

Re: 42PFL7422D/37 Service Manual Needed
I have a Philips 42 inch 42PFL7422D/37 that I got from a friend. He said one day it just stopped working. There is no sound or picture.
