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....
