Lg w2253vp

[spaceman]

Got another bad monitor in the office. Though this one is just over a year old. The positive side is that this is the only one of these out of the 6 from that purchase.

I think that the pictures can explain the issue better than I can with the first being the lcd in question and the second being what it is suppose to show.

And as always, I really appreciate any help that you all offer. Thanks.

Great - suscon caps are on a per with elite.
First test as befor is to reseat/clean the connecting cables.
Can we assume it has been tested on a different source if it has vga and dvi or hdmi can you try a different input.

Please can you update your profile with country and mains voltage

Re: Lg w2253vp

Sorry, profile updated (US & 120VAC 60Hz), contacts have been cleaned, and you are correct in your assumption. DVI, VGA (different sources), or just system menu all have the same result.

Re: Lg w2253vp

If all monitors are the same type is there any chance of borrowing another one to swap boards - that is the quickest way- to confirm a faulty board.As it stays on it doesnt look like a power supply problem. Its not the backlights nor the inverter. Can you post a picture of the panelboard/tcon may be fixed to the panel and needs careful handling.

Just to check you did do the cable where it fits to the panel

Re: Lg w2253vp

Although I could swap board with another one, I would rather not if possible since people are using them during work. And I did clean/check the signal cable going to the panel.

I believe that here's the pics (though I still don't know what a tcon is )

Re: Lg w2253vp

Ok Great pictures! That is a panel board or Tcon ( I just found out today that
if its on a monitor its called a panel board and if its on a tv its a Tcon)
Anyway in pic 2 near the connector there is a little white rectangle smd with a "k" on it - That is a fuse - can you test it.

Re: Lg w2253vp

Ah, thanks for the explanation, and the fuse seems to be good still at least according to my cheap multimeter.

Re: Lg w2253vp

The fuse should read the same as touching the probes together.



Next time its together something to try - dont think for a minute it will work

Switch on press the menu button and hold it for 10 secs
Release it
Press Engine and Source buttons at the same time for 5 secs.

It may perform a factory reset.

Or try this blindfold as it were- Perhaps do a dummy run on a working set just to check the fields are where expected.


1 Press the "Menu" button on the right side of the monitor. This will bring up the On Screen Display. If nothing happens when the "Menu" button is pressed, press and hold it for several seconds to unlock the On Screen Display.

2Scroll through the menu options by using the up and down arrow buttons located just under the "Menu" button. Scroll down to the "Setup" icon, which looks like a big cog. Press the "Auto/Set" button to access the Setup menu.

3Scroll, using the down arrow, to "Factory Reset." This setting is located at the bottom of the Setup menu.
4 Press the "Auto/Set" button to choose "Factory Reset" and then press the down arrow to reset the monitor.

Re: Lg w2253vp

Have you verified you're getting 5V output from the power supply? If yes, then try measuring the output of the voltage regulators IC602 and IC603 on the logic board (last photo in post #1) .

Re: Lg w2253vp

Do you still have the old caps, if you have the pictures of the board (both sides) then I may be able to tell you what location they should be in, just make sure the pictures are clear enough for me to trace out the connections.
