I have a Sony KP57WS500 that I picked up real cheap and it has a blink code 8. I was wondering if this going to be an expensive repair or not. I was hoping to get it fixed and give it to my dad as long as it doesn't get to SALTY in price. Also it looks like the green (middle) projector isn't turning on and the other 2 do for the 10-15 secs. that it does turn on ,could this problem be related or not to the blink code because the info I've seen so far shows the code to be Audio related.

Anyone out there can help...I just bought a 65 inch rear projection HD1080 TV and hooked up the coaxle cable direction to the input A hookup.  I then hooked up my DVD player to the DVD hookup and lastly hooked up my kid's Wii to the Input 2 hookup.  The Wii works fine.  The problem I have is that the DVD screen is blue screen and not registering the player which is operational.  Additionally the cable line that I have when hooked up to a different TV gets all 78 channels...but when I hooked it up to the HD1080, I get only 13 channels.  Not sure what to do...
