Some common causes are:
A component is failing and it is thermo sensitive. As it warms up it starts to work in spec, and thus the set can start up. Most of the time this type of component can be in the scan amplifiers or in the power supply.
The CRT is going weak. When its emission level is below a specific value according to the design of the set, the uPC sends a command to not allow the high voltage to start up, or it is not allowing the the electron-guns to be biased on. As the heater in the CRT warms up, the electron-gun becomes in to proper spec, and thus the uPC allows operation.
Eventualy the set will no longer start up, or what ever is failing will fail completely.
You can take the set in for a service estimate, but personaly I would be shopping for a new set.

I have used clear plastic sheets and silicon tire dressing for smaller problems like this, but no idea how well it would work with a large screen TV. The westleys silicon tire shine smooths out the scratches, and you place the clear plastic sheet on top of that and work out any bubbles then tape the ends. It pretty much changes a standard screen into a glossy screen with the added benefit that you can always replace the sheet if it is damaged.
I usually get my clear plastic sheets packaged with the new LCD screens I purchase for repairs and I just keep them in storage.
