Samsung LCD LE40R86 vertical lines problem

[remacomp]

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

What caps have you replaced and what caps have you used to replace them?

Can you post some pictures of the problem and all of your boards. Use the manage attachments function to upload pics.

Please check the voltage regulators on the T-con. I repaired an LE40R74 with the same problem. Did you get TV as faulty or did you own it when it went wrong?

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 my solution can help someone else too.

Cheers!
