I have a Dish Network labeled HD40-300 40" rear projection HD TV. From my searches online seems to be the same as a RCA D40W20 or GE D40GW10. Have seen references to chasis ITC222 and ATC221, not sure which this is.
The problem is that when I power the tv on, it flashes a green screen (with horizontal squiggles), then goes black. Any ideas or troubleshooting steps? If it is a (reasonably priced) part, then I could handle the repair.
Any help would be appreciated!
