This set is less than 2 years old.. really disappointed in Samsung. Looking on the bright side I know more about how my TV works now (kinda) I started a thread over on AVS but have not got any attention and I found this place when googling and it seems to be a much better source of this kind of help. I found a couple of threads dealing with my model TV and I was not sure if I should hijack a previous thread or start my own. Obviously I opted to start my own. I'll try to be as thorough on what I have done so far as I can.
Sunday afternoon I was watching TV and noticed what I am going to call artifacts that manifested mostly on light skin (white people) where it looked like the studio lighting was hitting them the most (cheek bones and forehead). This happened no matter the source. Anyways, not wanting to waste the rest of my Sunday diagnosing it I let it be. A few hours later seemingly out of nowhere the TV shut down and would not come back on.
Yesterday evening I had a buddy come help me take her off the wall and I took the back off hoping to find something obvious. Unfortunately that was not the case. Caps look fine as far as I can tell. Nothing looks blown. The lower right corner of the power board does have a faint smell of electrical burn but nothing visibly obvious. I see no holes in any of the chips on the buffer board.
When I plug it in the green led on the logic board blinks quickly once followed by a longer blink (Lets call it a dot - dash) While the dash is happening there are 3 clicks from the power board. 6-ish seconds later this repeats. I have seen tom66 point to that being DRV_RESET and usually being an X/Y main or buffer fault. On this model the Y-main is daisy chained off of the X-main so I'm not positive how to test them individually, but when I disconnect the power cable from the power board to the X-main board and plug the TV back in the TV seems to power on more normally, but I can't get sound of it and obviously no picture. I get the Samsung 6 red "power on" blinks from the red LED and I can see the red glow from the optical port on the input board, the red LED on the front blinks when receiving input from the remote so that seems to be working. Shortly after it seems to "reboot" and the process repeats.
I brought my multimeter home with me today, and while referring to tom66's "A guide to fixing/troubleshooting some common plasma TV problems" on this forum I started probing around. Probing the power connector from the power board to the input board looks ok compared to the silk screen on there. It's all low voltage it seems.
Now on to the power connector from the power board to X-main. While the power board is "clicking" and trying to turn on, the lower voltages (5.3v, 15v) do come on temporarily. While it seems to be trying to come on VS only jumps to about .7-.8v DC for a split second (I'm guessing because it never fully charges?). The VA line never does anything. Both VS and VA act the same whether the xmain is hooked up or not. The VS and VA test points are clearly marked but I have tested from the TP's and also at the connector with the same results.
So that is where I am at. Had I not read tom66 pointing to the 6 second blinks being an X/Y main or buffer fault I would have quickly pointed the finger at the power board since I'm not really getting voltage on VS or VA and that faint electrical burn smell, but now I'm not sure so ALL help will be greatly appreciated!
