Was using the monitor, suddenly the colors got brilliant (esp. the reds) and it died. a few days later it worked again, only for the same thing happening again. this time it didnt fix itself. nothing happens, not even the orange/green indicator comes on. i tested it with another power supply and it still wont power .up i have two of these and both power supplies work fine with the other LT765B

ladywoman197, 2 things for you to do. 1. disconnect-reconnect vga cable a few times from the DB15 vga port on the pc. If problem (pink hue) persists then try here: http://www.lesliewong.us/blog/2005/05/02/hp-pavilion-f1703-flat-panel-blackout-solution/ Your unit may need some new capacitors installed on the power supply printed circuit board. Read fixya profiles of "budmrtn" "12fixlouie" and also visit youtube for video clips of lcd monitor repair. Do the vga cable thing first!!! Could also be vga graphics card inside pc not making good contact with monitor cable. 12fixlouie
hope u r a professional..as u r handling chip-level repairing of monitor, knowing itz hazardous n dangerous..
however, check thoroughly for dry soulderings..(esp. at the crt base)..[this chance is maximum].. see if the base is loose or faulty.. yes, it can b the 'chroma ic'..but don't ignore the associated components..(esp around the base).. check video amplifier n sub section.. the colour diodes, transistors n resistances at the base..
for better supervision contact ur system admin/vendor....
Amazingly enough my monitor did the same thing and while looking for the serial number the problem got resolved. Since I don't know exactly how it got fixed I will tell you what I did. I turned the monitor off, removed the power cord from the unit, turned the surge protector off and back on, placed the monitor face down on my chair to read the serial number, reconnected the power cord and turned the unit back on. The problem was fixed. Go figure.
The part where you see some color bars and blinking green led is what we call MONITOR SELF TEST. A diagnostic pattern consisting of four colors (red, green, blue and white) appears, and the LED flashes slowly. this happens when signal cable from the monitor is disconnected from the tower and leaving the power chord for the monitor plugged in. If the monitor works properly on a different computer. then its a problem with the computer's video card sending out signal. im 85% sure that its a problem with your video card.
