This my latest recycle find; a nice looking Samsung LCD. When turned on, you get nothing but vertical lines completely across the screen. I haven't opened it yet; any ideas?
Thanks,
Jim

Re: Samsung LCD TV LNT4061F Vertical Colored Lines
Quite a common fault with these is bad capacitors causing this very symptom.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

You are right, it is the exact same board and model #.Comment

Re: Samsung LCD TV LNT4061F Vertical Colored Lines
While I am waiting on delivery of some high quality caps I ordered today, I scrounged up some spare parts for a temporary fix. With the capacitors replaced, it starts right up.

Re: Samsung LCD TV LNT4061F Vertical Colored Lines
I have a similar problem with a Samsung LNS3241. (dark screen, backlight on, several multicolored lines, no menu) I have replaced four capacitors on the upper right of the power board which is BN96-03057A. Output voltages test okay, except for the line to the main board, labeled 24v detect on the schematic. It is only reading about 5 volts. I'm not sure what the "detect" refers to. Any help greatly appreciated.Comment

Re: Samsung LCD TV LNT4061F Vertical Colored Lines
@kelly 24V_DETECT of 5V is fine. Probably best to create your own thread to avoid confusion.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I have had the issue you describe on 40" Samsung 720p panel (black screen with about 20-odd thin random lines.) It was easily fixed. Please create a new thread and it can be discussed there.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed... -
Hi,
I have a Samsung 55inch TV (UN55C6400RF). It has started showing colored vertical lines. I have opened the TV and the power board had one pin (out1-) which is discolored (Model # bn44-00358b). Can this be bad or is it the T-Con board (Model # D03464E0J09B6012066). Any recommendations on diagnosing the issue?
Thanks,

I posted about this previously but didn't get any response, and I have some troubleshooted a bit so I have more info.
The screen is full of horizontal "gaps" or lines that distort the picture badly, and after about 10 seconds of powering it on the screen starts to fill with red vertical bars that take on the horizontal pattern. After the screen filled with the red bars, they instantly vanished and then slowly started to reappear. I initially thought it was tab bonding failure, but after getting down to them and pressing each one I find zero change in the picture. I went... -
Greetings,
I've bought a used Samsung UN65NU6900FXZC LED TV. It worked fine for some time and then developed, at first, a single very thin (1 pixel) vertical stable blue line, from top to bottom, close to the left edge of the screen. Now it's 3 lines on the left. When I connect HDMI sources the number of the thin lines grow. After disconnecting and cold discharging I am back to 2 lines. The lines disappear at a rate of 15-20 minutes per line. So it does not look like a damaged LED panel. Any advice? Thanks... -
