Philips flat screen and Hd Tv

[philips]

Hi ! I have this Flat screen tv that quite working for no reason:\,and i tried to check it but i see all the capacitors are in good shape and when i turn the tv on there is just a black screen and i still can use the radio but no picture when i put it on PC,TV,HD. so i would really like to know if there is any possible reason that can cause this . Thanks in advance

Thank you so much

With the TV on and some kind of media playing (cable, movie, etc., hopefully you can hear sound coming out), try shining a flash light at the screen and see if you can see a picture. If so, you have a dead CCFL or inverter.
