    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 2 controls screen & focus.....see this after you found it plugin the monitor use plastic precision or small screw 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.

Un Plug the vga monitor cable to cpu.. if the monitor working good the OSD is appeard. If the monitor no display or OSD but the power LED is normal i think this is ABL problem. If you are the electronics or computer tech. repairman you understand what i mean.

Brightness and contrast increases suddenly


Check following:
1- VGA chord; is it loose or faulty?
2- Power Supply section not regulating perfectly.
3- Supply line from SMPS/Regulator power supply to EHT.
4- Brightness lines and controls (Resitance may be dry soldered or burnt)
5-Pin connection on rounded board of CRT neck may be loosed, Check it if loose than fit properly.
6- Adjust the precet for accelearting and focusing anode externaly fixed with EHT if inbuilt in EHT than only solution is to replace the EHT only.

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
