Question about LG Studioworks 45 14" CRT Monitor
I bought a LG Studioworks 452v model monitor at 2000. Recently my monitor started frequently change in color display. Now a days the color problem is permanent. Both red and black colors are shown as black, and other colors are also not shown properly.
Try changing or replacing the display cable ....Simple as that... might work!

The prob here is tht the cable has worn out and has loose connections/inter-connetions.thus the colour display takes up a differnt tinge when twisted in different directions. based on my personal experience i hav found out 3 ways to solve this prob. pick the 1 tht suits u. thus the solutions are:- 1) Open up ur monitor disconnect the 3 differnt connector pins n take it to ur local computer market, n ask for a replacement, usuallly u wil b lucky to gt an old wire, else ul gt a cable manufactured by another company that does not fit quite well.... wel, play around... cost: Rs. 0 to 150. 2) cut the cable at the point at which it causes the prob(for my monitor this was right near the connector).go to the local electronics market to buy the 15-pin connector that costs Rs. 15 only.. reconnect the wires to the same old order, refer to the cut wire... i think this is the best solution. 3)cal the samsung customer care and pay rs 800 to gt ur 5 year monitor fixed....( wch is utterly pointless). caio!!!!

Your red color circuit in the monitor is defective. Most common problem is the color IC.

Is your monitor by any chance sitting next to unshielded speakers or anything else which could generate an electomagnetic field? You can get some terrific colour shifts with these items. If you do have anything like this put some distance between them and the monitor. Also the auto degauss coil circuitry could be faulty in the monitor. Take it to a repair shop and ask the tech to degauss the tube and see what difference it makes. If it fixes the problem get him to check the degauss system. Don't try this yourself. There's lots of voltage running around inside a TV. Fix don't Fry BMW

your irf 630 is not original purchase it from proper LG authorised service centre it is costly but never become faulty again duplicate mosfet overheats if your green led is on then measure voltage at E.H.T.connect meter at output transister if E.H.T. is producing then meter should show 1 digit if not then 50v will show take care that signal cable should be disconnected if E.H.T. is not producing then check +vcc at horizontal ic it should be 12v. if 12v is not present then check regulator ic 7812 insmps
