I have a Samsung 52" model LN52a650a, just over a yr old, so warranty is expired. It's getting a solid black line down the left side of the screen, also on the left side the picture is very blurred, even when displaying the channel, or any menu or onscreen functions on the left side, picture is also darker on the left then the right! Any ideas?

SOURCE: Purple and white distorted fuzzy lines running up and down and side to side on tv

I just had my lower Y-buffer board swapped out to fix a problem similar to yours. After an hour and a half of on-time, the lower half of the screen would flicker on and off with the same appearance you mentioned. Changing out this particular board fixed it for me. However, since it has gone from top to bottom on your set, it may be more of a main board problem for you (that controls both upper and lower halves). Beyond this, I don't know any more. I am considering getting a service manual to gain more knowledge about the various PCBs in the unit so I can fix any future problems myself.

SOURCE: Black screen but have audio.

It's a pretty common problem. (If this is a plasma your post says lcd but it came up under plasma.) The no picture but sound problem is usually the y sus board. I've replaced 2 on mine now. The 680uf 35V capacitors usually are bulging because one of the power transistors went and took them out. This has happened to both of the y boards I had. One time the failing y board took out the buffer boards too, and once it did not. The fix is super simple and anyone with even the most rudimentary knowledge of computers or electronics can do the labor yourself. You should do the simple stuff first by just doing a quick test with a multimeter. Just check the power coming to the y board. After that you can just remove the y board by removing 3 cables and like 3 screws. Plug in the new board and it's done! You can source the parts from a place like shopjimmy or discount merchant. 3 boards were like 200 bucks. 1 board is like 100 bucks. Labor took me 15min. Think about that the next time an electronics repair place charges you 1000 dollars. Of course they check everything (Yeah right) and warranty their work (I don't) but if you check the service manual it states that this is the most common repair. Look for the Canadian manual online. Hope this helps!

SOURCE: Picture on Samsung LCD LNT5271F is blurred

Had this exact problem diagnosed by a local repair shop as a bad LCD panel. According to the technician there's a loose ribbon cable on the panel and it would cost as much to replace/repair as a new TV.

Same problem on my friends Samsung LN52A650A. Never did the firmware update cause that refers to a random shut-off problem. I replaced (2) 1000 10 volt caps next to a heat sink with 1000s rated at 35 volts @105 degrees C. The tops on his were a little swollen and you had to really look close. The caps were 2 0f 4 inline caps. They were the smaller 2. TV works.

Samsung LCD tv wont turn on


what the full model number of your tv?
the clicking sound is the result of a faulty power supply, some capacitors(blown heads) on the power supply for the output voltage rail of the mains board need to be replaced.

pls rate me!

Line in middle of LCD screen


I too had a black line horizontally across the screen (on a 52" d62). It was brand new and was as if the screen had been "pinched" at the end of the line and it radiated outward (in my case, the "pinch" was at the extreme left and line went out to the right, like a crack).

Mine was a factory defect (right out of the box) and was replaced (2 yr now and no issues). This line of yours may have been there from the start and maybe you just didn't notice it?? Not a slam, just an observation.
