Its 2 times blink error code that shows +B volt supply (+135 volts) is shorted, most probably horizontal output transistor is shorted, replace it.
If you are good in soldering parts in circuit board then take out horizontal transistor, check it, found shorted then replace it with same number.
Horizontal output Transistor Q502 number is 2SD2578 and available in
Part Store for $10
Let me know for further query, if any.
Thanks.
