Any idea on how to open up LG Flatron E700s monitor?
I looked at the back and saw only two screws but the shell does not come off after removing them.

Problem: the monitor only displays the image[complete screen portion] at the top 1/4 portion of the display area. The image is very shaky and distorted.

Probable Cause:
Broken PCB: I noticed that upon tilting the monitor in the exact upright portion [when plane of the screen is perpendicular to the plane of the table] the image stabilizes and it looks as though nothing is wrong with the monitor.

Tonnes of Dust: I also saw a lot of dust and spider webs inside the monitor so I want to open it up to clan it and make sure whether its the PCB that's broken or just a loose wire.

So please help me find a service manual for my monitor or a monitor with a similar casing

Please have it serviced by a qualified technician.

If you fail to discharge the CRT cap properly, the shock could kill..

I'm not planning to remove the eht cable[i don't remember the name properly, should have paid more attention in TV lab :p ]. Seriously I don't want to die. I just need to clean it up.



tried that already, only shakes the image a little more.

There is always hope, but you have to supply it.

I know, I wasn't warning you about the high voltage dangers but instead getting shocked by the low voltage power caps which you're likely to almost touch even trying not to.

Contrary to most tech class teachings, voltage arc'ing from a crt probably wont kill you. Maybe **** you up but not death.

The 170v caps can dispel a charge slowly enough to stop your heart dead.
At least power it off for 48 hours first

I'll take your advice, Though I have fiddled around with 14" and 21" TV's before but Never touched a monitor. problem is that all my data is on th desktop and my laptop is only good for nothing
Kaput??? that sounds like "Kaputt" in German which means "Broken" :D
I think that was what I wanted to write.:p

Well you could proceed with this DIY repair if you feel confident enough, but it'd be better to get it repaired by specialized technicians.

Looks like the horizantal deflection is dying, I can tell you from experience it'll likely be much cheaper just to pick up a new monitor.

Just make sure to get nothing less then 22" if you're planning to go wide-screen. Otherwise stick to the standard 4:3 ones for 17" - 20"

mmm probably it´s time for you to get a new one ;) there are many cheap flat monitors out there atm.
Why O Why do bad things happen at the wrong time.
I was saving money for PS3 :cry:
and I loved my monitor, I had it in front of my eyes for such a long time :(
and I don't like LCD monitors they give me a headache when I look at them.
I'll go and check on new monitors soon.

Just pick up an IBM 17" or 19", IBM CRTs are probably the best ever made. Dell's are also good, but at all costs avoid Compaq!
