Question about Mitsubishi WS-65809 65" Rear Projection Television
When no signal is applied I get a solid/static blue screen.
I'm looking for a replacement signal board for Mitsubishi WS-65809. There is a board on the signal board inside of an RF cage that I believe is the problem. When I first encountered the problem, I was able to clear it up by tapping the cage. When that no longer fixed the problem, I removed the signal board and checked the solder joints and connections. Is there someone who can troubleshoot the signal board and/or the daughterboard.
The board you seek is the doubler (2HDW) module.. a lot of time reseating the board will solve the issue. If HD still works, this board is likely you problem. This board upconverts all non HD signals to hd to put onto the screen. IF HD doesn't work, you more likely need a signal board. This board has all the settings on it and is much more difficult to replace.
