Question about Computers & Internet
I have a Haeir L32a2120 LCD 32". When I press power, the screen comes on for about 2 seconds then goes to black. I ordered and replaced the backlight inverter board, and now the picture comes on very dim, like the lamps will not fully power up, just flickers. The parts reseller has sent me three more boards but the same problem exists. What else could it be? Bad lamps? Power supply board? Pease help.
The contrast and brightness are controlled by the main board. If that board is not sending the right signals, the picture is dark.
