Won't power up, LED flashes with a clicking noise from the speakers when plugged in

The title basically says it all.

If I have the unit plugged in, the power LED flashes and the speakers click every few seconds pretty regularly. Seems it is a fairly common problem. I found another solution where you reset a similar monitor it by plugging in the DVI connector right after click, but I was unsuccessful after a number of tries.

I disassembled the unit and got into the PS and disconnected ALL the connectors. I measured 5V and 12V on the PS and they remained stable.

However, if I connect the control board and connect the power led or the speakers or both, it still does the flashing and/or clicking (respectively, of course).

I peaked at the digital board, but thought I would write something up here before I do anything TOO stupid. I am wondering if there is any way to mimic that resetting of the digital board through the DVI on the board itself (maybe some way more reliable. . . like maybe I can hold/short a reset circuit or something).

Thanks

    First of all, thanks for the speedy response.

    But I am still a bit confused as to what you want me to do.

    I found a datasheet for the ROM and it seems that pin 5 for the chip is the serial data. Does this make sense? Are you suggesting that I lift that pin off the board (it is a surface mount IC)? Will just shorting it to ground work? Or is the no 5 pin on something else?

The major problem with this system is memory deletion.I mean the programmable rom ic bordering the ps.What you need to do is unplug the no. 5 pin and plug it back immediately after switching on i a sure you it will be working.

Headphone plug is not working


The plug on the headphone itself can easily be tested with a ohm meter at the plug end--if two black bands it is stereo, check with the meter from the section at the tip of the jack to each of the other two segments to see if continuity with each speaker in the head phone.

About the only way the socket it plugs into goes bad is one speaker will not work or it does not cut the sound out when inserted to a internal speaker if the unit has one.

No Sound LGW234T-PF


The LG W2343T does not have speakers. So you can't plug in a 3.5 mm audio patch cable between the computer's line out or headphone jack and the monitor. (Similarly, other devices can't provide sound to the monitor.)

Are you using a desktop or a laptop? If you have a laptop, make sure that the correct audio drivers are loaded for your OS and make sure that the audio isn't muted (look in the lower right on a Windows system in the tray for the speaker icon). On an HP laptop, we had to use the Component Services (Control Panel > System and Security > Administrative tools > Component Services > Services in Windows 7) and stop all audio services and restart them. Then reboot the computer to use the internal speakers at a reasonable volume.

For any unit with external speakers (required for a desktop, optional for a laptop) , connect the speakers to the audio out port (green for 3.5 mm for single connection speakers, see the manual for other speakers) or the headset port. Next make sure that the device drivers are loaded and correct for your sound card (or motherboard audio). (Control Panel > Hardware and Sound > Device Manager). If your sound isn't active, look at the Sound header. Then choose Manage Audio Devices and the Playback tab to select the desired speaker option. (Again these are for Windows 7).

If you still have no audio, make sure that the speakers have power (USB cord or AC adapter plugged in depending on the speakers). If it is USB powered, try a different port or a powered hub. If you have an AC adapter, check if it is warm. Some speakers have power/volume knobs. So check if they are on (if there is an LED, that is an easy check). If still no audio, try a different audio patch cable, if possible. Otherwise, try different speakers. There may be a damaged wire preventing the speakers from working. Depending on the problem and if your speakers are under warranty, it may be worth fixing or not.

Documentation for the monitor is available here: http://www.lg.com/us/computer-products/monitors/LG-lcd-monitor-W2343T-PF.jsp . Click on the Support tab.

If you want to use a stereo receiver with RCA audio inputs, you'll need an adapter or a 3.5 mm to RCA m/m audio cable.

I hope this helps.

Damn Blinking!


You can buy a used monitor about $50.00 in the US. or You should take the monitor to an authorized repairman. IT IS NOT recommended to fiddle by banging a defective unit WHICH has HIGH voltage running through it.

Sir Help me with my Compaq monitor MV520 it won't turn the power led flashing orange to green continously


it could be th epower supply and it could be the monitor.
power ON button should not flash orange regardless what you do. it should stay green. then orange. not orange to green to orange.
try the monitor on another PC if you can fine one.
the other thing is are the 2 monitor similar (CRT to CRT and LCD to LCD), you can't mix the the two, they will work but need different video driver to function correctly.

Edwards,

What you mean by replaced the fuse? Are you replaced the capacitors on the AC Adapter. If so, Then it's not the only problems. The main problems is the backlight inverter needed to be replaced. Go check out my website @ www.3rd-rocks.com

Tv does not turn on


When TV does not start, and sometimes you hear a clicking noise, that means that the TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.
