If I eventually open it up to do the connectors, I'll post an update here, but as it is, I can live with it. Long live the LN52A650!
Since we are having our family room painted, I used this opportunity to remove the back cover. Everything looked fine connection wise, but now I have NO PICTURE! I'm not sure what happened, whether it was during the moving process (removing TV from wall mount), or me removing the back cover. I hit power and the backlight turns on, but I have no on screen display, no picture on any inputs. I can hear the startup and shutdown sounds, and see the red light blink when sending remote codes.

Can anyone provide some guidance?

Thanks but no thanks. I got it working again! I took the cover off again and rechecked the connections. One of the ribbon cables was not connected - which is odd since I did check them. Anyway, it's working again, but the red line is still there during the warm-up period, so I think my panel is going bad. I'll milk every last once out of it until that happens or a nice 60" set finally lands at an attractive price point (translation - my wife says yes).

LIke I said, time for a new set. There are a lot of tv under 2K at 60". Look at online stores.

My 47 has been a champ #knockonwood til now. My landlord was putting up new curtains for me (love them) but accidentally stepped on the cord for the antenna ripping that part out. I'm now trying to figure out how i can get local free over the air tv on it. I have a 2 tuner silicon dust dvr, but no way to get it on the tv atm via hdmi. Maybe I'll just cave and get a i7 mini pc. Dunno yet. Anyway everything else works just fine.

I lost mine 52" last year. Vertical stripes began to appear and would go away after 30 minutes but after some time they stayed full time. I still have my Lnt 5265F and last May bought a UN65H6350.

Mine has been getting those stupid vertical lines on the far left of the screen! But after a while they go away. She turned 8 years old this month! I love it and hope she keeps on ticking!

ln52a650 right side screen flicker

The left side of the screen flickers at startup until I manually warp the right side of the screen....but its really hit and miss, because I don't really know where the pressure should be and stuff.

What causes this, and is there a solution I can apply?

Thank you for any and all help!

Mine is doing the same thing, guess i'll try to get it fixed if it doesn't cost 1/4 the price of a new tv

Samsung LN32A -- Repairable?

The TV model is Samsung LN32A450C1D, purchased in 2009.

I tried to turn it on and heard a loud pop, and it turned off. I turned the TV on again and seemed to work fine with no picture/sound issues. A few days later, my wife turned it on and heard the same loud pop and said she saw spark(s) come out of the back. I didn't try to turn it on after that because something was obviously wrong and I didn't want to risk further damage.

Looks like the jumper J839 has melted, maybe the associated capacitor is fried. Any suggestions?

(I first posted this on the "LCD Flat Panel Displays" thread, but this one looks more appropriate.)
