SOURCE: Hitachi le49a509 led tv black screen. I can see the menu screen with a flashlight test. There's 3 boards in the back. Tcon, power supply and main board. Which is the problem?

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

You already have done all the necessary tests. Your LCD Panels Drive board which comes after the T-Con on other side is faulty. You have to replace the LCD Panel itself to fix the problem. The cost of the panel may be more than the price of a new TV Screen.

I have a LE49A509 Hitachi Television that will turn on but the screen is black. At least the blue light comes on and stays on but no picture at all. What is wrong and how can I fix it


Do flashlight test to see if you can see a picture. If so the issue is with the tcon board. If no picture with flash light issue is with the inverter board that powers the led's.

Where there is anything in picture that is white in colour, the white area is filled with a scattered pink colour-


could be 1 of two things - tcon board or av board. I'd check th etcon board first though. I just replaced a tcon board that caused the screen to look like a picture negative.

Thanks,
Michael
