I'm also facing exactly the same problem. I bought my TV from bangkok on 21st Nov 2011 as per following details (MAKE - OCT 2011,MODEL CODE - UA40D5000PRXXT, VER NO - AC 06).
For the first 9-10 months TV was perfectly fine, then problem of image distortion started coming which autocorrects after 5 min or so and i thought it to be cable problem. After exactly 13 months,problem gradually worsened and became permanent atleast for the first half an hour after the TV is switched on. Interestingly after half an hour if i push back the TV from top left corner then problem mostly gets corrected.
On contacting the service station we are told that the panel has to be replaced and it would cost about 25,000 INR!!
This is absurdly high amount and not sure if there is a simpler remedy. Any opinions are welcome!
I am based in Mumbai, India and we about 12 months back we bought a samsung led ua40d5000 tv and after about 8-9 months of usage half screen started turning white. Initially, this behavior was seen only for some time and it use to auto-correct itself, but now after 12 months when the service warranty has expired, this issue is more prominent now and our TV is unusable. On contacting the service station we are told that the panel has to be replaced and it would cost about 20,000 INR!! which is very high amount!! considering that I just bought TV about 12 months back. I am really disappointed and think I made a wrong decision of buying samsung TV!! and I would advice people is using caution before choosing SAMSUNG, because they can conveniently pass a defective piece, which will start complaining just when the warranty expires.
Please people, any advice or workaround that can help and save some of my hard earned money, let me know
