Samsung Syncmaster 753S Problem Intermittent darkening of screen . Sometimes white horizontal streaks along with characters on screen. On opening cover and slightly tapping video PCB solves problem ....

after 4 or 5 yrs EHT ( transformer that supplies voltage to CRT TUBE - MONITOR TUBE ) becomes weak - then 1 of the indication is ....picture becomes dull (less brightness & less contrast ) 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( 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, ----- 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 sevice 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..

Problem in samsung syncmaster 793MB is that when shaked,colours change but when unshaked,screen is green or there any solution to this?


I think there is problem with your display card.
If you could try testing with another monitor you ll get confirmed. In that case you have to purchase another VGA card and install it then it works fine.

No diplay in Monitor

The blinking LED usually denotes that no signal is reaching the monitor. Do you have another monitor you can attach to the computer to test it? It sounds like it may be a computer problem, not a monitor problem.
