I'm sorry to hear that your television will not turn on and the indicator is blinking. I would like to assist you with this. Generally, an issue like this is due to the set being unable to develop the proper voltage to control the CRT Tube and that can be caused by either a failure of the circuitry or the tube getting weak. You may want to contact a local television repair technician or visit
Sears Home Services
to arrange a Sears Technician for a repair. I do not recommend working on this set yourself, there are very high and very dangerous voltages inside of the TV cabinet and it is very hazardous to work around.
Please let me know if you would like any further assistance.
