NES No display of game on TV

[Jeret]

Hi my very well kept NES 001 , from the box has no display on tv. It has power. I tried changing the av cables, tried diffrrent games but nothing coming up on tv.
Anyone here faced the same problem, any solutions ?

1) Try this NES on a friend's TV.
2) Try another console on the same inputs of your TV.
