MY Samsung LN-T4661F 46 Inch 1080p LCD HDTV is having several issues. For the last year or so, upon initial turn-on, it takes several minutes for the TV to turn on (about 7 or 8 beeps). When it does turn...

Taking several minutes to turn on problem is usually due to bad/unstable DC from the power supply, which can create a lot of strange symptoms. That willbe the first palce to look.
Please read mu guides for details and post back what you find on the power supply section first. We need to fix the delayed turn on problemfirst before trying to fix other symptoms.

My tv keeps clicking on and off at startup. Sometimes taking 3-4 attempts to turn the screen on. Also, it will start without picture only sound

Your #1 suspect: LCD inverter, which supplies white light to the screen.

Your #2 suspect: the switched power supply, specifically 24VDC lead that supplies power
to the LCD inverter.

Either way, enjoy your 40-in set while it lasts, since its soon to be heading for a TV repair service.

40" Samsung wont turn on

The gradual death you describe is probably caused by the decay of an electrolytic capacitor in the main power supply. It would require a capacitance meter with loss measurement to ferret out the bad part. Eventually, the supply will fail to start at all and leaving it on will cause the weak part to decay faster.
You might want to do some advance research on the cost of a replacement supply which you can probably replace on your own. These are normally on a separate board that will be visually related to the AC coming in and will have larger than average components on it. For safety, leave the AC disconnected overnight before you start doing any surgery; the power supply can deliver a nasty shock if not allowed to discharge.
