Hello, I recently picked up a 70 inch Samsung tv. When powered up the power light blinks twice and the LEDs flash and change brightness but then turn off and the power light blinks and the LEDs flash again. After some looking I ran across several other people that had the same issues and replaced the main and power supply board but no change. If you leave the tcon cable unplugged to the right side the tv responds normally to the remote and has sound in between the reboots. One person said that they found that if they plugged the tcon cable into the main board after it was on they got a perfect picture. I figured I'd give it a try and it worked. Stays working until you turn it off and then you have to start it by unplugging the cable and plugging it in with the tv on. I looked on eBay and I see people selling the small bios chip on the edge boards from working TV's with broken screens. I've never seen that item before. Is that a possibility and is this a normal problem for this model? I figured I would see what happens if I unsoldered the one on my tv to see if I could in the event I do order one. By the way the tv acts the same without it. Any info would be greatly appreciated. Sorry if this sounds kind of rough but it's my first thread.
