I need your immediate help : LE40B750

by Abdollah0098 - 4/4/10 9:41 PM

Hello
Friends need your immediate help.
I have an LCD model LE40B750.
A few days ago a new Firmare T-CHL7DEUC 3000.2 download from Samsung's site and I got upgraded as well. But I realized that after the upgrade option is disabled Alternative Software.
After a few days out of curiosity I enter the service menu and change the tuner section, and after I press standby button remote control, LCD off and the other does not work.
Each time the power plug connected sensors constantly blink red lamp and screen goes white and bright but will not start and stop after a few seconds and again repeats the same state.
I opened the back door and used the reset button to reset factory, but it was not effective.

some serviceman told me to solve , first I have to find a similar LCD mainboard to IC flash like jtak. is it true?
Please Help me how can I Boot my LCD TV ?

Thank you for your attention dear friends
