RS232 Cable

Ok

Your PC has an HDMI output, so you will need an HDMI/RCA adapter (around €10)



You will also need an RCA/Scart adapter (configurable as Input/Output). Ask the seller. You need to set it to Input. (around €5)

The red cable is for sound right, the white cable is for sound left, and the yellow cable is for video.


And there you go, you will be able to watch your PC on your old TV (with sound as well) ^^

Hello,

You won't be able to connect your TV to your PC with a "serial" RS 232 cable...

No, I want to connect my PC to my TV.

Does your TV have a SCART socket?

Yes

Great!

Behind your PC, you have the ports that allow you to connect your machine to your monitor; can you tell us what the outputs are?

You can show us a photo if you're not sure :)

I'm sorry, sir, but I didn't understand anything.

Can you tell us the brand and model of your PC (it's written on the side or the back)?

My computer is a Packard Bell

That's my computer...

Thank you very much.

to be clear:
if you have an RS-232 serial port behind your TV, it's for updating the firmware.
the RS-232 baud rate is limited to 115 kb, so you'll have a hard time transmitting images through this cable... or it will be slow!
