Re: Samsung lcd le40a866 vertical lines
thanks for answer tom66, but i'm pretty sure that it's not problem with bonds.
First, like i said when i warmed TV or only mainboard, without touching tab bonds, its temporary fixed.
Second, i tried with pressing on tab bonds but nothing changed
thanks anywayLeave a comment:

Samsung lcd le40a866 vertical lines
I have problem with 3-4 year old samsung lcd. You can see it on attached picture. Vertical lines are not always on same place, they follow text, subtitles,...
I read about it, and some people said that it dissapear when TV is warmed up.
So i used hair dryer and warmed up boards and TV works ok till next day.
Then i made reflow on bga chips on main board, but same result, it worked but when cooled it doesnt.
I read a lot similar threads, but didnt found solution.
Does anyone have suggestion what to do?... -
Re: Samsung LCD LE40R86 vertical lines problem
Woah. Problem solved.
Sorry guys, and thanks for fast reply.
I bought faulty tv one month ago, and like i said i changed couple caps on power supply board. After that tv turning on but i had vertical lines. I tried with new t-con but had same problem.
Last night i found some firmware and reprogramed 24c256 with my top853 programmer and thats it - problem solved.
Original remote doesnt work, probably coz wrong firmware but with universal remote it works.
I hope that...Leave a comment:

Samsung LCD LE40R86 vertical lines problem
I have problem with LE40R86. I changed couple bad caps and now i can turn it on, but i have only vertical stripes on screen and after couple minutes i can hear clicking relay which turning off and on tv. I read about it and someone says that it could be problem with firmware on ic1803 (24C256).
I have programmer, but cant find bios. So where can i find it?
Or anyone have idea what else to do?
thanks -
