Re: SAMSUNG LA40A656 with vertical lines at startup
Did anyone experience a similar problem ? I would purchase a new t-con board if I would be sure it's not planned related..
Thank you

Re: SAMSUNG LA40A656 with vertical lines at startup
Hi Diah,
I did change that cap already (it's a 470uF) but the problem is still there... I did another round heating the the T-CON and it started immediately so I'm almost sure the problem is focused there.
I've noticed that some of the ribbon contacts are starting to peel off, I've position them carefully and it's now ok again but will eventually need to replace them as well.
Below some closeups on the T-CON in case it help..

Re: SAMSUNG LA40A656 with vertical lines at startup
I've mande a run on all 3 boards, PSU, MB and TCON.. at a first run it wasn't really deterministic, but I've then focus on the TCON and I was trying to turning off and on with or without heating the board to understand if there were some cause effect.
After a 3 or 4 runs were I was basically under the 20 seconds to a full working TV, it kind of get always OK and now startups correctly immediately. I've give it a good couple of hours of viewing and it was basically OK (it stopped working...Last edited by v0ltair3; 12-31-2016, 02:52 AM.Leave a comment:

Re: SAMSUNG LA40A656 with vertical lines at startup
I've made a cleanup of PSU, MB & T-CON board as well as reseat all cables including LVDS & ribbons that go out of the T-CON + factory reset, but the problem persists
After some time of the startup the TV goes "normal" as stated above and stays like that for hours to come until the next time turn off & on. (this time took almost a minute, but when "cold" it usually take a bit longer)
Below some pictures of the power supply & main board....Last edited by v0ltair3; 12-29-2016, 05:27 PM.Leave a comment:

Hi Diah,
first of all, thanks for the support, this is actually a nice angle..
Indeed the TV "recovered" by it self after about 10 seconds... I was wondering it was related to the swap of the different sources but its apparently irrelevant.
Does it somehow helps with the root cause analysis ?
Thanks...Leave a comment:

SAMSUNG LA40A656 with vertical lines at startup
Hi Everyone,
I've just come across with this amazing site while trying to troubleshoot a recent problem that's happening with my TV set.
From 2 days ago, whenever I turn on my TV I can't see a clear image, rather I see that the image is basically transformed into a bunch of vertical lines like below:
Now if I try to loop the different sources for a few seconds (say 10 seconds), i.e. try to loop between the analog and digital sources, I eventually see a "normal screen" and its stays like that for as long as the TV is turn on,... -

Hi There,
I on computer science field working as a software engineer, nevertheless electronics has been an very old hobby of mine... I've fixed my Samsung TV a few times always around the power supply unit, but this time the problem is different so after some google I've came across with badcaps.net
Hope to learn and contribute back to the community.Leave a comment:
