Question about Samsung SMC-150F 15 in.CRT Conventional Monitor

Color adjustment of CRT Monitor

I have 3nos. of Samsung 15" color Monitor based on DP14L15L whose EHTs were burned out.I have replaced all the EHT and all three started working but with a color problem in all three of them. In one of them blue color is a bit too much, in one of them the red color is a bit too much and the other one is having excess of green color. There is no preset to adjust the color. I've tried to interchange the base boards, but the problems remain all the same. Some one told me to go to the "Service Mode" and adjust. How can I do this? Please help me!!!

SOURCE: Color Problem:

in Monitor CRT Red-Blue-green cathode guns are there.. Mixing of these colour we can get the original colour chrominace technique. if any of the colour gun is faulty we would get more REad or blue or green picture. Measure RGB voltages. you can verfify which gun is faulty. if then check RGB processing circuits. Else there might be problem Chrominance colour decoder system. Contact service centre

Unfortunately, this is not a fixable problem. Samsung CRT monitors are well known for losing color; they have defective cathode ray tubes. I recommend that you buy an lcd screen. sorry if that wasn't what you wanted to hear! don't forget to rate

Hi I have a Samsung 56V monitor . The letters have been appearing blurred for quite some time .

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...blurr... (less brightness & less contrast , no clarity ) ........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, [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 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..

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.
