Poor picture quality, the picture is blurred and

You have problem with convergence. Have you tried adjusting in the users menu. This is a common problem in this type of TV, usually two convergence amp need to be replaced and sometimes sets of resistors are also to be changed.

I have a sony 50 in rear projection. 9 years old

Sounds like the CRT tubes are going out which is fairly common on Sony. Inside the back of the TV there are 6 knobs - 2 for each is for focus - dont touch - the other for brightness...turn down the brightness just a hair untill the lines go away.

What can cause horizontal white lines in a projection television? The TV is about 10 years old, and I am told it may be the internal power source. Could that be true?

can you see a pix or is it all white with lines running diagnally about every 1.5 inches--if you do not have a pix only lines problem is the 200 volt line feeding the crts(off flyback transfofmer)

Sony KP-43HT20 Projection TV

5 times blinks is error code for No Good White Balance and you said that picture is very green.
As you know TV is approx 7 years old so it needs RGB gain adjustments.
If you are TV tech person or know about TV repair, let me know to guide you further. Or contact local TV repair shop to fix it.

Sony KP-53V85

My unit is 9 years old, almost 10 (in 2 months) and started the same a couple of months ago. The only way to fix it is to have them serviced by a tech and replace the projectors. Its just the age/use of the unit catching up with it.

Many resellers sold them with an offer to sell you an optional maintence service where they would fix/clean/replace the projectors for upto 5 years after purchase. I'm not sure if they even have the parts anymore since these tv's are no longer produced. After market repairs are likely to cost as much as or nearly as much as buying a new flat screen tv.

Green lines on my Sony projection

Those are called retrace lines and they are the result of the blanking pulse not having the desired effect. This could denote a problem in the Horizontal section of the TV. In this case the green gun is not being turned off as it goes back to the left side of the screen.
