This is a problem wit your stk392-110 convergence IC's - One has gone bad and the both should be replaced. Also, check the large resistors near the convergence IC's - it sounds like one of them may have burned up..

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary..

Several black lines on screen


The TCON board or the LCD panel is faulty. Can confirm by replacing the TCON board.

If the converter goes out does the tv not do anything no screen light uponly red standby light?


if your question is that if cable or sat converter goes off for any reason , will your tv display a black screen , then the answer is yes , without an input most all tv sets will display the opposite of full white , this being full black , also any on screen displays might not work as well (no video to sync too)

LG LED TV has sound but no picture. Went out all of a sudden. Image shows with flashlight. Flashes for split second on power up and power down.


Your screens back light has most likely failed and or the voltage controller for the back light, both should be replaced.
