Noise appears on TV Output

Post by Asit on Tue Jul 08, 2008 3:28 pm

Crying or Very sad
Hello Everybody,
I have a problem for last 2 to 3 years, and alhough I had tried a lot but I am unable to solve it. Hope anyone from you can solve it.

I have two N-Vidia Graphics card, one is AGP & another one is PCI-Express.
The problem is that rolling horizontal bars appears on the TV screen when attcahed to TV, but there is no problem in monitor. I have already checked earthing, UPS and also contacted Customer Care, who lastly told me to take the card to Service Centre. But I was unable to take it to the Service Centre due to some problems. Although I am planning to visit the Centre in coming 3 to 4 days, I prefer to ask all of you.

And further more there is a interesting thing. Once a plan comes to my mind to check if there is any problem with my system by replacing the N-Vidia card with ATI card. And to my astonishment there is no noise at all with the ATI card. The TV Output is perfectly fine. Therefore I conclude that the problem is with the N-Vidia cards.

So guys, plz help me whether I am right or wrong ? Should I visit the Service Centre or is there anything else to try?

even i had a nvidia card which gave me noise using the 5 PIN S-Video Port.

How many pins & what port do you have in the ATI card ? there are chances that the 8 pin card performs flawlessly.

lemme know Smile

U r right Rahul, the ATI is the 8-pin one and it has the same S-video port. But what is the difference between 5-pin card & 8-pin card? Why there is the problem in the 5-pin one?

And more interestingly, if I run the system in the backup power of the UPS, there is no noise at all?
What can I do then?

actually the 8 pin one is more advanced as it also carries sound signals with it & all in all i would advice for you to avoid 5 pin nVidia cards in general. try getting a vga or dvi to composite cable for your nvidia card, it should solve the problem.

as for the ups issue, its a peculiar situation, maybe its got something to do with the voltage of output that the gfx card gives , which makes it noise free.
