Question about HP TouchSmart IQ770 PC Desktop

1 Answer

I have an HP IQ770 desktop. I want to watch something from the internet on my television. I've hooked up the S-video cable and the RCA cables, but when I tune the television to AV3, I just get a black screen. How would I transmit the picture on my computer to the television screen?

Most of the time, it works automatically. however in this unfortunate case there are a couple things you can try. the first is changing the resolution on your computer - try a few different settings. in many cases computers are set to a resolution that the TV can't support.

if that doesn't work, i'm not sure which operating system you're using, but there is a "connect external display" tab in control panel --> personalization that you can mess around with easily and sometimes help get it functioning.

hopefully that works for ya

No not that bad just kidding.


Your body carries Static electricity.
An All-In-One desktop computer is set up like a laptop.

Once you remove the outside covers, the Static sensitive hardware components inside, are exposed.
You CANNOT just touch any metal frame, as you would for a regular desktop computer, and relieve your body of Static.

This means you need to wear an ESD wrist strap, and have it's alligator clip attached to a good ground source.

This is an example of an ESD wrist strap,

I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
(I feel an Anti-Static mat is unwarranted)

You can set a large metal serving tray (Unpainted), on the table you're working on, and connect to it.
Or perhaps a large metal knickknack (Unpainted)

Horizontal Cover

Just from a quick search for the Power Button Board and cable,

(The Power On Button assembly presses against the Power On switch.
The Power On switch is what should be bad. Of course you will know once you get to it.
The Power On switch is part of the above assembly)

Vertical lines on HP TouchSmart IQ770


Hi,
Welcome to Fixya. Vertical line on the screen was caused by a bad video card or cable. If the video card is embedded or built in on the motherboard of the computer. It means that the motherboard needs to be replaced and would be better for a technician to check it so that we can avoid more problems. If you can check the warranty of the computer so that you can send it for repair free of charge.
Thanks
