My sony 27" wega (8 yrs old) just died. the standby light blinks, but not in any pattern. The picture is green/yellow with about 15 horizontal lines on a 30 degree slant. Should I replace the screen or power supply, or should I just get a new tv?

The lines you see on the screen are called retrace lines and are cause by the absence of 200VDC that power up sections of the CRT.
This type of repair might not be a DIY due to the number of measurements to pin point the defective part(s) and the high voltages around the circuitry. There could be a fuse resistor that is connected from the flyback transformer to the CRT that is open, if that is the case you could also have a video amplifier IC shorted.
Good Luck.
