It could be a lot of things.
First, if the Tv is clicking, your fuse is okay and the standby power supply is okay. Any lights flashing? I have repaired some of these philips for power supply regulator. It will click on but on the standby works and not the secondary voltages.
It could also be horizontal or vertical failure or anything really. Was there any humidity? See some water on the circuit?
If you're not a tech, send it to a shop. My shop has free estimates, so maybe a shop near you can tell you your problem and at what cost. Should not be over 125$ for repair.
