It sounds like 1 of 2 things is the issue.
1) The Acer is not outputting to the TV (which is an easy fix)
2) It's possible the VGA cable has gone bad.
Let's try this
Connect the VGA cable to the Sony TV
Connect the other end of the VGA cable to the Acer.
Once they are both tightly secured
On the Acer locate the Fn
key and the F5
These keys are used to activate the TV out on that laptop
To do that
Hold down Fn
while holding the Fn
key down press the F5
Look and see if the PC input is available on the Sony. You may need to power off the Sony and try again.
It does take a few attemps with FN+F5.
If that does not work I would replace the VGA cable. You can buy a replacement at Radio Shak, Walmart, Best Buy, Staples, Office Depot, etc.
