SOURCE: LG 17" MONITOR MODEL 700E (COLOUR & SHAPE PROBLEM)
THE PRESCRIBED ARROWS ARE FUNCTIONING WELL FOR INCREASING THE VERTICAL SIGE OF THE DISPLAY OF THE MONITOR.BUT THE HORIZONTAL AROWS WHEN OPERATED ARE NOT ABLE TO INCREASE THE HORIZONTAL DISPLAY OF THE MONITOR TO FULL SIGE. PLEASE GIVE APPROPRIATE SOLUTION.
THANKS

open unit, adjust focus pot on flyback, may have 2 focus pots.
do both until satisfied.
If the problem varies with temperature (on time), then you may have a failing flyback.

The normal crt monitor have a demo display when you unplug the vga cable to PC like this image below.. 
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....
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...
For LG & Redfox you found LM1269NA Visit this site for seaching semiconductor matches www.alldatasheet.com Good luck.

The unit is saying goodbye, in it's special way. There are very limited repairs for CRT's nowadays. A good cheap flatscreen is always available. Trust my word on the CRT's. Sorry. Thank you, Dana
