LG Studioworks 700E

My monitor is 3 years old. But recently it has started to give a minor problem which is quite irritating. Whenever I start my computer after a few hours, the monitor starts with a dark color as if I had set the brightness setting to minimum and the picture is a bit hazy, even the letters appear slightly hazy as if the monitor is decades old. However, after some time,the brightness & contrast return to normal & the picture & letters are CRISP as ever. Please help. my black LG Monitor 700E is about 3 years old. now the problem with it is that when i start my pc the brightness of monitor goes to 0 and it remains for about 1 hour . when i hit the monitor after 1 hour then it becomes normal , brightness comes.. it is so irritating that i have to wait for 1 hour before i could do anything on my pc.. please assist me regarding this problem. thanks..

Re: LG Studioworks 700E

It sounds like one of the capacitators inside the monitor is malfunctioning, these little things store a certain amount of necessary power and then discharge it when it is needed.  If it is malfunctioning, it could explain why it takes so long to charge, and why when you hit it, it suddenly comes on.

This is fault within the main mother board, can be related to the power supply or the processor secttion but is sure a lowering of value in capacitors.
If you are able to open the monitor and use a Hair dryer, the spot will be identified immediately as a heating in sections of the power or the board will switch on the monitor and thus confirm the area which can be pinpointed with a closer heating.
replace the suspected capacitors with the correct value , insert into the PCB with the correct polarity.

Hi i have a LG 700E CRT monitor i am using this monitor for last 5 years but now i am facing a problem that red color in the monitor is not coming . please assist me regarding this.

The most likely cause is a broken red signal wire in the monitor cable. The next possibility is a bad connection at one end of the cable going to the CRT board inside the monitor. It could also be a thermal-fatigued solder connection in the red cathode driver circuit on the CRT board (this can often be found by visual inspection after removing the CRT board shield).

If you don't find one of those three problems, you'll need to use an oscilloscope to trace the signal from the input cable up to the red cathode terminal. (Caution - high voltage here!)

High pitch sound coming from my old LG 700E monitor

High pitch sound maybe an indicator of a defective monitor or a wrong or incompatible resolution setting of your display properties. The usual is that you have set the resolution higher than that the monitor can hold. Boot the pc in a safe mode. This will give you an option to set the resolution to that resolution accepted by your monitor, the usual is 1024 x 600 or so, avoid higher resolution than this.

LG Studioworks 552V monitor incompatibility problem.

Right, well, IF your TV has a DB15 Female Plug on it then you CAN, connect it up and it will work, as a second "Monitor". OR If the laptop, has a "Composite Video" a Yellow RCA socket, then you can, connect to the TV's Composite IN. & it will be a second monitor. Otherwise you cannot, the VGA signal is NOT compatible with a TV's input. SOME cards have a connector that plugs into the DB15 and to the TV, but they are "Special". In saying that though you can "Micky Mouse" things together and get an output, but it real poor quality, and disappointing results, there are various posts on the net about doing this if you wish.
Remember DRIVERS, you also need the drivers installed & setup correctly in order for the hardware to work. As a tip, When connecting to a TV, always connect like this......First, plug all cables into TV's correct Video input(s). Connect up the Sound, plug all cables into laptop, turn TV ON. NOW, start the laptop, you should now soon see the an image.
NOTE: Some laptops & other devices, have HDMI out, sometimes, the AUDIO is not passed through, the HDMI cable, & the Audio must be run from Audio/Line OUT on laptop to AV IN on TV.Also some laptops have a socket that a multi-way 4/5/6/7 pins. A connector plugs into this, you then can connect to these connections, as you would normally. Connecting this up will be easy. What you do is get a yourself a set of the right, for your setup, cables. That uses EITHER one of the formats, of these described, below. You will need, either, a THREE way Cable, or three separate " Coaxial Cored" Cables with RCA PLUGS on them. ColoredYellow, (Video) Red, & White. (Audio) AV. OR If you have SCARTConnection Sockets, it's a big Black Socket at rear of unit(s), you get aSCART Cable.& It's all inside. Now some units, use a standard calledComponent Video, that uses, a Green, Red, & Blue Plugs. Now, with the Component setup, you will also ,need, Two more Cables, for the AV Audio. these are, Red & White.(So with Component Video there are 5 Cables/Plugs in all). In any event ALL Cables go Color to Color, at each end, plugging into the corresponding Colored RCA Jacks, on either machine, or VCR or TV. Now if you have SCART, then it simply plugs in only one way. It is that simple. So connect up with the leads your set uses, and select the correct "Input" from TV/Remote, it is NOT on a "Channel" it will be on AV, AUX, and Press "Play" on VCR/DVD whatever.... should be all go.
