After the bulb replacement, the lamp hour should be retested. If you replace the bulb, and after the lamp hour reset to new bulb; and after that you replace it with old bulb, it won't work. In most cases, the lamp ballast too have to be replaced with a new bulb, and it is a good practice too. If the TV refuses to start up, there are many reasons for that. It will be best to contact any experienced service technician; I suggest. If you wish to get some details; visit the site linked here. Pull up older posts.
