Re: sharp lc-46d62u
It could also very well be a main board problem considering the lines seem to appear behind the OSD. -

Re: sharp lc-46d62u
Checked for bad caps?
Since it works for a few seconds, it seems that a bad cap could be causing a voltage regulator to go wonky. What do you think?Muh-soggy-kneeComment

Wondering if anyone has addressed an issue with the SHARP 70β LC-70UD27U having thin black and white lines running from left to right horizontally on the screen. I snagged this TV set from a neighbor since I have been successful in repairing numerous other TVs. I assume this probably happens to other TV sets and may have been addressed in another thread. If so please point me in the right direction.
What I have tried so far.
I have tested all HDMI inputs with the same results.
I have checked for firmware updates.
I have reset to factory settings.
I have removed... -
This is only my seond post and so far i am very impressed with the forums.
I have a Sharp 50bj2ke which is 6 month out of gaurantee and has devoloped horizontal lines, i have tried to research as much as possible but i am no further is diagnosing the issue. When i turn the tv on it works good with only a thin line right at the top of the screen which i could live with but after a couple hours of use the lines start to appear in the middle of the screen and now the bottom.
The small white box thing in the pics is not the tv its a reflection from the window
Any suggestions... -
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 doesnβt 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... -
Hello again! I have come back for some wisdom and hopefully for some guidance with this problem I'm having. The TV is a 4k 55" Sharp LC-55p6050u and the problem is every other line of the bottom 32 lines flickers out, comes mostly back, then flickers out again, and repeats this continually. The lines on the bottom right of the screen go out completely while the lines on the bottom left are affected so slightly that it's almost impossible to see it. There is a gradual gradient from appearing almost perfectly fine on the bottom left, to an obvious problem on the bottom right.

Hi all
I have lines on the screen...which is an age old problem that can be remedied by watching Youtube videos and getting out the tape.
My issue (after successfully fixing a different sammy tv with a separate tcon board and isolating the side of the panel...):
This tv has an integrated tcon...so it is a bit more confusing when trying to isolate the clocks.
It has a c ribbon and i have taken each end out to see if that will isolate the lines. instead, it makes it much worse ALL over the tv!
So....i don't know what end of the C ribbon to work with...
