MV-1FZ picture probs

[ROM-Lover]

Hi,
i own a MV-1FZ and it´s running well but the picture signal seems a bit low cause the channel information of the TV doesn´t goes away.

Normaly the channel of the TV is swichting automaticly if i power on a console like Hyper 64, Ps 2 or something.

Powering the MVS results in half TV screen and half MVS screen.
So i think the signal is low.
I don´t think it´s a voltage prob cause Hyper 64 is runnig well on the same Jamma converter.


Channel info


Auto switch TV

Anyone know what to do?

How is it connected, SCART? Looks like the TV doesnt like the sync rate.

 

[ROM-Lover]

Yes, it´s scart connected. Any idea how to modify the sync rate?

Do you have the blanking pin connected?

Can you try it on another TV?

 

[ROM-Lover]

On another TV it´s running well. Channel info is going away normally.

thank´s for that

Another problem is that the sound is always humming in the backround.

I suggest connecting the blanking pin on the SCART connector (pin 16 IIRC) to +5v via a 100R resistor. Most problems that occur on SCART tv's are due to this either not being connected or being connected incorrectly.

Sound humming is most likely a ground issue, do you have your audio grounded properly?

Sound humming is going if i take out the normal TV connection.
But channel info isn´t to get away on the MVS.
But thank´s for your help
