Toshiba 72MX195 DLP TV DMD CHIP

[jukky]

Hello everyone....I'm new here and I want to see if I can gain some knowledge on what to do with my Toshiba 72inch DLP TV.....It turns on in the beginning until about 5 minutes later ....I get a Green wave on the bottom moving up and down....after a couple of more minutes the wave gets bigger and bigger coming from the bottom of the TV until the top.....Is their someone who knows what this problem is.....I spoke to tech support at Toshiba and they told me that it's not the Bulb....And that most likely it's the DMD Chip.....Help me out.....Thanks.
