How to opan lg crt monitor back case - LG Flatron Ez T710BH 17" CRT Monitor

There should be several philips screws on the back panel. (WARNING: Because you are opening a CRT, there is a extremely high voltage coil on the back of the CRT in the center. DO NOT TOUCH THIS WITH ANYTHING as it is DANGEROUS if you do.) With the exception of possibly a power supply fuze which you should be able to see next to the power transformer (where the power cord comes into the CRT case), there ARE NO USER-SERVICEABLE PARTS INSIDE. I recommend you buy a cheap LCD screen to replace it and dispose of the CRT through a recycling program. I hope this helps you.

Bad solder connection on CRT circuit board resolder all bad connectios

how many years back did you buy this monitor because monitors have some life after which they starts creating such type of troubles

You've got components that have gone bad, probably from age and the normal heat inside a CRT monitor case.

I hate to say it, but it's really not worth fixing. You can usually find a used but working 17" monitor for under 20 bucks.

Thank's

I have also same problem with LG Monitor 700E, LB(in). I want circuit diagram/systematics of this monitor in PDF or any other format. Thanks in advance.

as you are electronics engineer so let us discuss technically.

as you are unable to see green colour means you might be seeing picture of magenta colour

as technically

red+blue = magenta

crt has got three cathodes

your two cathodes circuit is fine one ckt that is green cathode circuit is not working.

for that problem your will have to check

• cable from computer to monitor
• loose contact in crt base.
• crt connector loose
• voltage on green video output.
• green video output transistor might be defective.or print loose.
• circuit related to green video ckt
• green video signal coming to green video ckt.
• & finally crt defective (in rare case.)
• hope this will help
• good luck.
