There are several things that can cause it. You are best to have an expert technician come in and take some test on it in order to determine if it is from vertical blanking failure or something else. It is not easy to fix this yourself, if you have no experience, because there are a lot of parts that have to be removed before you can reach the components. It could be as simple as a loose connector ribbon or a bust capacitor, but it could also be more complicated. Hence, in my honest opinion, better get a qualified technician.

Hope that helps!

I have 2 lg 1941s lcds after 5 minuts it becoms blank and again turn it off and on then display comes but it repets contineously. we doing repairing work at smd level also . so pls tell me solution for it


hi,
First of all check the power supply board for any budged capacitor. Its a common problem in lcd . If found any budged capacitor replace the same will solve the problem. If there is no such capacitor then ,
You have to check the back light inverter board of your tv. If the inverter transformer in the back light inverter is faulty then this board will overload the powersupply and result in shutdown. there is no repair possible with the inverter board. you have to replace the board.
Have adde the picture of Budged capacior for you reference.
