same problem that everybody else be report . I have one for about 3 month and it start blank , so I return it for another . this one have work for about 6 month and it be now do the same thing . basically you turn it on , and within 5 minute , the picture go black . if you pull the plug and restart it , it 'll come up again . the problem seem to be get worse , as for a while it would only require 1 restart , and now it have be require 2 or 3 . I do notice the 2nd one 's test pattern be now yellow and blue , instead of white and black , which be apparently because of color streak which would be all too visible on the original test pattern . this seem pretty dirty of Panasonic . on the plus side , the image be fantastic when it work .
