SOURCE: what component failed in my 17"CRT 753s model samsung moniter?

Hello,

Your vertical deflector circuit is going out. This is really not economical to repair, the chip alone is $12-15 plus if you have any other parts in the circuit going out plus labor. You can pickup 17" CRT monitors for less than $15 from goodwill or craigslist.

Sorry to say but I think its time to retire your 753s

SOURCE: 700e Lg crt monitor problam power on eht on but not display

The normal crt monitor have a demo display when you unplug the vga cable to PC like this image below.. fd6b6b9.jpg
Note:
If the crt monitor green LED light steady and heater beam have light, the horinzontal and High Voltage supplied to tube is completely good. If you encountered this problem just focus on video section of crt monitor. But before you start... find the flyback transformer behind this they have two controls screen & focus. After you found it plugin the monitor use plastic precision or small screw philip driver for safety to high voltage at horizontal area choose screen control rotate it to clockwise direction follow this....
5b5166c.jpg If the display responses or from dim to lighter 100% you have a problem to ABL find this at the bottom of horinzontal section near at flyback transformer pins trace the line of ABL for dried solder, open resistor if nothing happen find the Video IC at chroma section and replace it. follow this...

The CRT has screen adjustments, there is a screen adjustment button on the monitor that will allow you to adjust the width of the image as well as the height etc.

Disply very slow please help me


after 4 or 5 yrs EHT ( transformer that supplies voltage to CRT TUBE - MONITOR TUBE ) becomes weak - then 1 of the indication is ....it takes few mins for picture to appear...........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 ) ----------iam from bangalore (09986222774, sathyavijayasarathibabu@ymail.com) ----- here EHT's price will be around US $ 10 & for my customers (in bangalore) i will take another US $ 12 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.....
