Hi people.

In my company we are using the following hardware combination: a Asrock motherboard model IMB-150 and a LG tv model 43LH541V-ZD. Everything worked ok until we buy a new batch of TV's identical but with a newer firmware version. With this new combination in approximately 50% of the tests I made I cannot see the display when booting or when I enter BIOS (pressing key without seeing anything).

I have tried a faulty board with other TV's or the older TV model and I have no problem.

I asked LG to try to downgrade the TV firmware but the support guys told me this is impossible...

I have tried a lot of BIOS combinations with the same luck.

Does anybody know a solution or any new test a should do?

Thanks.
