TDP158: Differentiel output signals going periodically down

STG

I sent you a direct email, would you please check? We can communicate through direct email.

Thanks

Hello David,

I think I have found the problem. It has probably nothing to do with the TDP158, and the corresponding circuit.

It looks like the display is turning off the termination periodically when the input timing does not exactly meet the expected input timing requested by the EDID.

So it looks like that the display is hanging in the following loop:

1. Turn on termination
2. Detects a input timing
3. Checks the input timing
4. Since the input timing is wrong, it turns off the termination
5. Wait ~1 seconds, then goto state 1.

I'm now going to change the timing. Will let you know what happens....

Regards
