The green led on the power supply board is on.
The red led on the deflection board is on.
The -28V green led on the deflection board is on.
The +28V green led on the deflection board blinks.
The other +28V green led (closer to the edge of the deflection board) is off.
The +9V green led on the deflection board blinks.
Any ideas? Thanks!

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

Located in the power supply section of the unit. There is a pico fuse (soldered in fuse) that opens up and there is no high voltage. The second click that you hear when the set is turned on. This can be diagnosed With set unplugged, with an ohm meter with a simple continuity test. I think the pico fuse is 4 amps , I am not absolutely sure. I have seen this problem in that unit previously. There is also a convergence problem that occurs with that set. Scrivitron.

Good Day, Gil;
Your problem is in deflection circuit (115+v) check these: FP05, DP15, Q777, QH01, TH01, T701, etc. BUT suspect C707 1k pfd, 2kv, and check all the pico fuses (brown) 2" to the right of cap. Good Luck, big IRISH.
