Question about Televison & Video
Hello destinee81, let me help you.
I often see things like that, mostly occurs because the problem panel.
To ensure it, first turn tv on than wait a minute until you hear a sound from a channel tv.
After you hear a sound and still no pict, knock gently the panel with your hand ( not too hard but not too soft). If you see a flashing light (on area you knocked) , that mean back light panel is OK. Open rear cover , there are 2 boards (Power board and Main board) and 2 board attached on panel (inverter and T-con) , "beware with high voltage on power an inverter board". Check connection on t-con and main board, clean it with brush to remove dusts on it. if still make no changes , replace the t-con board.
Second, repeat first step above. If there are no flashing light on knocking area,. that problem from inverter board. Replace it. If any problem and questions, please let me know.
I hope that will help you. Thanks.
