Horizontal line on screen,no picture but sound


Problem with vertical IC. Try resoldering, loose solder after sometime is common problem for almost all tv manufacturer since this ic generates more heat and legs are so tiny that looses contact easily. Good Luck

There is no sound on my insignia flat screen what do I do


Try hooking up the powered PC speakers to the AUDIO Line out RCA jacks to see if you get the sound there, if you do, then the problem can be in the power amp section (make sure to check the on screen sound setup menu that the speakers are not set to OFF), if no sound at the RCA jacks either, then the problem can be in the sound processor circuit in the main board.

Have sound but no picture


I would check the connections to make sure they are good. The video connection could have gotten knocked loose. Sometimes they just come loose.

Insignia ns32lcd no picture just lots of vertical colored lines


Usually this problem is caused by the connections for the LCD Controller(TCON). If you disconnect and re-connect the cable until it works correctly it will usually solve this problem.
