After 4 or 5 yrs EHT ( transformer that supplies voltage to CRT TUBE - MONITOR TUBE ) becomes weak - then 1 of the indication is ....DISPLAY WON'T COME BUT LED BLINKS........so solution is EHT ( also called as flyback transformer ) should be replaced....... {{ few details about EHT---- its size will be around 3inch X 2inch X 2inch ---it will have 2 or 3 knobs to adjust focus , brightness ------ at bottom around 10 pins will be there ------- from EHT 1 thick red colour cable goes to CRT TUBE --------- on EHT its part number will be there }} -------- so if user is a technical person having idea about components ( resistors, transistors, diodes, etc ) , having tools like multimeter ( to check components) , soldering iron, soldering lead, flux, desoldering wig ( for removing components), etc also little experience in servicing field( very much compulsory) ----------------- then user can remove EHT from main board ---- take to electronic shop ----- buy same type EHT --------- fix to mainboard ( knobs on EHT should be adjusted according to picture --- after switching monitor --- this adjustment is very important ) ----------iam from bangalore (09986222774, [email protected]) ----- here EHT's price will be around Rs 250 ( US $ 6 ) & for my customers (in bangalore) i will take another Rs 500 (US $ 11) as service charge......i don't have any idea about EHT ' s price & service charge in your place.........since it is very risky job i suggest to contact monitor service engineer ------- because they are highly experienced & can fix this component very easily....

    SOME TIMES ALONG WITH EHT....A TRANSISTOR ( BIG IN SIZE & FIXED NEAR EHT) ALSO GETS DEFFECTIVE...........SO IT SHOULD BE COMPULSORYLY CHECKED BEFORE REPLACING EHT.....

If this behavior is relatively consistent, I would suspect the "mains capacitor", an electrolytic cap on the output of the AC bridge. If vibration affects behavior you may have cold solder joint(s) in the SMPS circuit. Knowing what current the monitor is drawing at turn on would be helpful.
