I suspected that the PSU capacitors had failed and as long as the TV would attempt to power up there was unlikely to be damage to the semiconductors, IC's and transistors so it would be worthwhile trying to repair it by replacing them. A simple repair that would take just a couple of hours to complete would avoid all the plastic and metal being recycled, a significant proportion of which, particularly the plastic would end up in landfill or being washed out to sea.

I recently repaired a neighbours 32 inch LCD TV which had started to behave erratically. It was difficult to get it to power on and when powered on it would switch off after 10 minutes.
