Hey guys, I have the toshiba 57hdx82. The tv worked fine except for the zig-zag issues (bad hyperboard). I removed the hyperboard from the signal board and sent it off to be repaired. After getting it back and reinstalling everything again the set is dead.The red power light comes on and stays on for fifteen minutes then goes out . It will make a small click, then you hear a low noise like a amp powering up but thats it. I've worked with circuit boards before and was very careful handling everything. I tested 11 fuses on the main power board and they all checked out ok. I doubled checked my hook up connections a half dozen times. Is there anything you could suggest I check for or try? Do I have to reset something? I have a service manual for a 65hdx82 but it should be good for this model also from what I read. I'm down. Any help would be greatly appreciated!!
