YOU HAVE A BAD GREEN CRT. UNIT IS NOT WORTH REPAIRING SINCE YOU WOULD HAVE TO REPLACE ALL 3 CRTS FOR THE UNIT TO SET UP PROPERLY.

Seems like your RED CRT is shorting out or failing. Do you notice any other colors besides just red having problems? The blinking of the red light eight times is a High voltage error. It could be your D board but I'm thinking it is more likely the red crt is probably shorting out.

Re-insering the flyback wire is usually very easy. Push in and give a slght turn and check to see if grabbed. It sounds as if there is more issues than flyback wire. TV should turn on without one crt connected

Green and Red guns seems defective and requires replacement.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Minium is the green picture tube need to be replaced, if you can take the front cover and access panel off there is a control with 3 focus and screen controls.
you can adjust the 3 screen controls to possibly get a little more time out of it before the crt's need to be replaced. careful if you turn them down too much there will be no picture, and if you turn them too high the tv will go bright and shut off
