My KP53V45 has sound and a very faint picture all in green with a number of horizontal lines. It also shuts down after 10 to 15 seconds. Is this a projection lamp issue?

Sounds more like a color wheel, if the color wheel is not working properly the on board computer will shut her down. And will get weird colors or flickering colors.
Sometimes will also make noise.

My sony tv stars blinking 5 times in a row, then the picture goes black for a second comes back then goes black again and it keeps doing it non stop

tv has a blanking picture mute circuit. adjust the screen controls which are located behind the speaker grill in front of set. there will be a access panel to unscrew in center and then you will see a black 4 inch square box with 6 physical knobs. 3 control screen the other 3 controls focus for red, green, blue. turn them down and slowly start turning them up. fixed.

Power on then off

Check the settings on the screen. If they are set too high set will cut off.

Tv comes on for a few minutes then goes off

If you take off the front bottom panel of the tv wich is easy. Then you will see 6 tuning knobs at the bottom middle of the tv .the top 6 control contrast for the lights dont mess with those. the bottom 3 are the power to each is bottom left if your screen went blue it makes sense that the red is starting to go but if you turn down the power to it left 1/8 turn it should fix it for awhile .Its easy.

two three-pin voltage regulators near the left side (looking in from the back) bend over from the heat and short to a ground rail. Check and straighten them with the power off and the unit unplugged

52 inch sony rear projection t.v.

Whining sound most likely is a bad flyback transformer. You are probally looking at a 350-450 bill depending on the repair shop. If your picture was "great" go for it. If the tv has a lot of wear let it go. Nothing the repair shop does to fix your problem will make your picture better than it was before it went out. Somthing to contemplate.

Big screen troubles....

It is either going to be a shorted blue CRT (picture tube) or a driver board for it. I suspect the CRT itself.
