Question about Sony FD Trinitron WEGA KV-27FS120 27" TV
Five blinks is the error code for an AKB (auto kine bias) error. What this means is that the set isn't able to balance the three color guns (red, green and blue) of the picture tube properly, and it's blanking out the screen.
To get the proper colors, the signals for the three colors need to be balanced, and Sony sets have circuitry to do this automatically. Other brands don't, and when they go out of balance you see a picture that starts to show tinting or colors that are off. As the picture tube ages, it gets harder to adjust the balance until finally the AKB circuit can't anymore, and poof, the picture goes away. With a 17-year-old tube, it's not surprising.
There isn't anything that can be done to fix the picture tube, it would need to be replaced. But the cost of the tube and the work required to get it set up after installation makes it completely uneconomical to repair this TV. A new picture tube is nearly $200. Then special tools are required to set the tube up (a process called convergence), so you'd need to find someone to put it in, and possibly pay to have the old one disposed of. A new 32-inch LCD set is around $350 now. Treat yourself to a new one.
