Something has failed and the tv is going into protection mode to avoid further damage.

Unless you have the technical skills, training and equipment there is no way to diagnose this further. You haven't stated the make or model nor given any details of any flashing lights which some models display as a diagnostic aid, but even if you had the tv will still need professional attention.

This sounds like a problem with the power supply. Usually capacitors on the power supply board tend to dome, bulge or dry up. The damaged ones can be seen on the power supply circuit board when the back is removed. The dry ones have to be removed and tested. The caps can be replaced at a repair shop for around $200, but if the power supply board has to be replaced it can cost a little more. It all depends on the shops repair fees.

When i switch my tv on it has a habit of switching itself off. The red light will still be on and a little green light below it flashes. some days it does it somedays it doesnt. Some times it does it once...

The television is switching itself off to protect itself because there is a problem with it. It may be a bad capacitor, which is usually the case but you have to catch it before it gets any worse. Because then the television will switch itself off and not come back on. The light will just continue to blink and on top of replacing the bad capacitor the entire board the capacitors are attached to might need to be replaced as well as the power supply and main board. Please do not keep turning your television on while it needs repair because it will put itself into a coma and contact a service provider asap.

I just bought an HP mini 210 - 2080 and its keeps on turning off by itself.Sometimes it goes on but then it switches off again and again!

Try logging in safe-mode and see if it switches its self off.
To log on in safe mode, power the laptop on and keep pressing F8, choose safe mode using the arrow buttons, continue to log on. when you successfully log on, leave the laptop for some time to see if it will switch itself off, if it does switch itself off, then definitely, that will be a hardware related problem.
if it does not, then that's a virus causing it, email on [email protected] to solve the software related problem.
