Samsung 753s - picture became too bright

Sir,
Picture on my 753s is sharp, but too bright. Controls are working - I can set it brighter, but not darker.

I found service manual for 753s, but did not point of origin of G2 voltage and have no idea how to regulate it.

Please help me with this problem.

check you monitor controls!! check the monitor's contrast control and brightness controls. these are the push buttons on the front of the monitor. or they may be knobs that you have to rotate either left or right to adjust the image on the screen. if it is an lcd monitor then please refer to the user's manual for that monitor.

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 ) ........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( 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, sathyavijayasarathibabu@ymail.com) ----- 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..

Picture dark and will not adjust brighter


This usually means the monitor is approaching the end of its useful life. Time to get a new monitor.

Brightness Problem


Hi,

Since focus adjustment using the flyback rear controls (EHT) has no effect, then it could possible mean two things:
  • the EHT is defective (most likely) at least the controls; or
  • the picture tube is already weak.
A workaround is to replace the filter capacitor of the ~70V leading to the collector voltage of the 3 color drive transistor. Normally used to replace with is 100uF/160V.

Of course best would be to have the EHT checked/replaced.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

To even things out you need to use the controls on the monitor to lower the brightrnes. to acceptable levels. When playing a DVD there are seperate controls in the software and your graphics driver to adjust the Video Overly settings. Look for settings called gamma and brightness in the video overlay settings in the windows display properties panel. This should help even things out some. Deal is to crank down the brightness on the monitor and crank it up in the video settings in windows. It will make the DVD's brighter and rest of the time the regular screen darker.

Color and brightness problem


Has it been dropped? At first it sounded like it may be have been an intermittent short if the CRT guns, but it's hard to say. Since it doesn't seem to be the cable, it sounds like this one needs component-level troubleshooting.

Samsung 753S focus problem


Focus controls are on the back of the flyback transformer. You may have bumped one while the back was off. Due to dangers working on live circuits I recommend you have a service professional adjust the focus.
