Question about Televison & Video
LCD tv's don't have bulbs, they have CCFL tubes that don't burn they worn out very slowly.
Your problem has nothing to do with them, it's caused by a failing power source - the capacitors have started to age and dry and when they are heated by the normal functioning of the tv they start to conduct some electricity (instead of being isolators) ; that overstresses the source and triggers its protections - the tv stops - the current drops to nearly zero - the capacitors cool down - they become isolators again - the source restarts, the capacitors heat up again and the cycle repeats.
The tv must be opened, all aged capacitors must be replaced and every other component in the power source checked for damage. I think this is a job for a pro.
