Hello,

Welcome to JustAnswer!

I am Pete, a TV expert, and I'll be happy to assist with your question.

Can you let me know:

1. Approximately how old is your TV?
2. What is the full make and model number?
Customer: replied 4 years ago.


the old tv did it so got a new one. the new tv did it so took it back and got another and thet does it. the old tv is now upstairs and works fine so the problem must be where it is situated. have tried plugging the tv in other sockets but still no good.

Hi Julian,

As the TV appears to work normally in another location, this suggests that the TV itself is not faulty.

If the TV was connected to an overloaded electric circuit then this can cause the TV to seemingly power on and off randomly as other electronic devices are switched on and off.

If it is an overloaded electrical circuit, how is it that it does the same thing happens when plugged in to other sockets in the house via an extension lead?


 


would copper pipes that are boxed in the wall behind the tv have anything to do with it?

Expert:  Pete replied 4 years ago.
If the sockets are connected to the same circuit (i.e. the same fuse in the fusebox) you will see this effect. This is common in older houses where the wiring has not been modernised.

It's also common wiring practice for upstairs and downstairs sockets to be on separate circuits which would explain why it works ok upstairs.

Copper pipes will not have any effect on the electrical circuits.

there is not a lot on that circuit so what should i do to solve this?

Expert:  Pete replied 4 years ago.
Hi Julian,

If the TV works ok on one circuit but not another, and there is nothing obvious on the same circuit causing it to cut out when they are turned on, (e.g. high powered appliances such as a kettle, iron, hairdryer, microwave, etc), then the circuit will need to be tested for faults by a qualified electrician.
Modern TV sets are very sensitive to slight changes in voltage, which is why the TV may cut out whilst other devices remain unaffected on the same circuit.

Pete.
