WS_55511

I am new here hope not doing this wrong. I have a ws-55511. I recently was watching regular Tv , i went to menu and switched it to the DTV(HD) using the OTA antenna! It has worked great till yesterday!! IT shut the tv off and it took me forever to get back into the tv to get it to switch back to satellite. I tried it again.. trying to watch HDTV and it shut the tv off again, other than the HD not working the TV works on other devices well! I am wondering if like the others it is the DM board? and the other things you have mentioned

[email protected] is email i would like to see that fix you have sent others!! as i cant afford 500 to fix it
