For the last month or so the TV has been having trouble turning on. Numerous attempts to turn on the unit had to be made. Two days ago the set will not turn on. The red light flickers when we use the remote or the button on the back. Sometimes you see a green flicker and then back to red. Please help.

Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
That problem is usually cause of faulty capacitors on the power supply board...
If the capacitors is faulty your TV turn on after a lot of attempt until the TV is totally turn on...
In that case you need to replace the bad capacitors on the power supply..
How can you find where is the faulty capacitors?
The bad capacitors is usually leak/bulged on top in that case you easily find it through visual check...
If going through a cable box you may be loosing signal from time to time. Try playing a DVD to rule out the possibility that its your tv. Try replacing cable box, or add a cable amplifier. Hope this helps.
i suspect it is capacitors on the power board that are failing on it. I am not familiar with this particular model. But i would say that is what it is, you can usually tell which ones are bad because they will be bulging at the top
According to the manufacturer, to reset the entire unit do the following:
1. Press and hold "Menu" and "Channel +" on the TV.
2. Using other hand, press the power button.
3. A small screen should appear in the top left part of the screen.
4. Using the remote, select "Memory Recall" and select.
5. Power off and re-boot the computer
6. Run channel auto-scan to regain the picture.
As long as the remaining warranty is still in place, that is normal procedure. You can request a new one or to have the existing one repaired, but in reality, repairing your set is equivalent to getting a refurbished one. The refurbished ones are just ones that have been repaired under warranty when returned to Sony from a store because of a warranty exchange. Normally warranty claims that occur less than 30 days from purchase are handled at the retailer without involving the manufacturer until the unit is returned by the retailer to the manufacturer.
The exchange for a refurbished unit is just a way to have your problem resolved in as little time as possible without effecting the warranty.
Hope this explanation helps. (I've been a warranty station for numerous companies,)
The most expensive part of a Plasma TV is the panel. Without the panel, the unit is only good as spares for the motherboard. The power supply could well have blown with the impact of the bottle. You could try and claim accidental damage on insurance, however it might be too long ago since it happened :(
Without looking at the set I would think the problem was in the optic block. An expensive repair, but, since the set is only four months old it's under warranty.
Go to the service section of Panasonic.com and find an Authorized Service Center (ASC) in your area to have the set repaired.
