wobbly graphics

[billyo]

i can add an external monitor on my laptop and i don't have any problem with the graphics, but if i connect it to a tv it will work for about 10 minutes and the graphics starts getting wobbly..i don't have a video out on my laptop so i am using a video tuner with a video out..can someone tell me what's wrong ..or do i have to get a new laptop..

What do you mean by Wobbly?

I have never heard the Video referred to this before. What are the graphics doing exactly? If you are using it and it is working correctly on the second computer monitor, it should then also work correctly on the TV, unless the output that is going to the TV has a problem.

What type of Laptop is it, model, and what Video card is in this laptop?

I have a Dell Inspiron 1000, with 512 MB and 40gb..what i mean was that the graphics start to get wavy after 10 minutes..it only does it on my tv,and doesn't do it on my ext. monitor.

he may need a converter from the shack.

If it works for any amount of time it would not be something a converter would fix.
I would first suspect a bad tuner. Maybe it, or something in it is overheating after 10 minutes. I'm assuming some kind of external tuner (also assuming you don't mean FM modulator). Would also suspect cable from laptop to tuner or cable from tuner to tv.

If your tv has svideo or rca inputs you could probably use a vga to rca/svideo adaptor and go straight in.
