i have a problem with my pj, it was working ok until my brother cracked the front glass on the blue tube. . i have now replaced the glass, i removed the tube to do this but now when i try to power it up it seems to be ignoring the remote control,it will eventually come to life,fans running but no way can i get any light from any of the tubes. the projector had no power at all for about three weeks. any ideas? thanks in advance.
