TV broke down!!

[SnoopNL]

Hi my strong lcd tv 42" broke down
It ran perfectly for a year or a bit more.
Now when you insert the power cord.
It goes in standby and pops to the green color led so it should be ok.
But in 2/3 seconds it jump back to red.
When you press the input select button nothing happens on the screen.

At all time the screen stays black.

I already tried replacing the power input unit.

Does anyone have some help please?

There is nothing that you as the user can do to fix a modern TV unless you are a trained service techican.
Call the repair service before you cause more damage.

There isnt even much that a service guy can do. LCD tvs have hundreds of thousands of transistors & stuff. If you bought it with a credit card, your card might have given you 2 years guarantee. But you also opened it up, so I wonder how that affects your guarantee?
