The four blinks usually means one of two things. Either the vertical IC is bad or you have lost B+ to the IC. First, check the voltages and if they are in spec, go for the IC. I am currently working on one that has no sweep signal from the jungle IC so that is another possibility.

Only if you are missing the + and - 13 volts B+ to the IC.
