Question about LG Studioworks 700S 17" CRT Monitor

1 Answer

Can't get LG CRT monitor to work at all.

I am piecing together a desktop system for my daughter for christmas. I have an LG CPU and am trying to connect an LG CRT monitor which i got from somewhere else. On the motherboard, there is a monitor connection but it is male and so is the connector on the monitor. There has been a graphics card added to the computer and presumably this has been set up with a monitor before but although the CRT fits the connection perfectly, it is not being recognised on bootup and stays black.

I'm presuming that the monitor is alot older than the CPU. is it possible to get a male/male adaptor cable so i can plug it directly into the CPU's motherboard and if i do this, will it be sufficient to make it work?

apprently there is windows XP on the CPU. i can't see that though obviously LOL!!!

If the computer has DVI male, you simply need a VGA to DVI adapter.
However, the plugs on the computer should all be male, and cables coming from the monitor female. It seems you may be trying the wrong port.

Try a different CRT monitor on your computer.
Try your CRT monitor on a different computer.
See if the problem "moves" to the other computer,
or whether your computer has problems with *ANY* monitor.

LG 700E CRT 17" monitor,
problem with the monitor Display cable. it is damaged.

Normally monitor will receive 3 colors red, green, Blue signals from CPU. If one cable i.e Red wire connection is missing in display cable which is connected to monitor, Red color image on monitor wil be replaced with other fade color.
So, need the replace the display cable or display connector!

Power is on but self display & cpu display not
probably itz either minor case of improper ground/cpu fan/faulty power cable..
or major case of faulty or defective main board/ram/daughter or addon card(s)..

..plz do check the following as in order:..
the Hardware part:..
1)a)in power on mode, open/unplug the data/vga cable of the monitor from cabinet..see if raster or 'osd' is appearing on the monitor screen..if so monitor is ok..else replace the monitor and see..[not applicable in case of laptop]..
b) in case of laptop try to get output from external display unit/monitor using vga port..if there's proper display in there..the problem is probably with either the 'lcd'or 'ccfl' or 'inverter circuit'..

2) if u hv a graphics card, replace with a standby or onboard and see..[not applicable in case of laptop]..

3) unplug mains supply..pick open/remove the cmos battery..check (above +3v)..resit..

4)see if the ram(s) is loose/faulty..open clean/remove carbon & or oxide formed on the teeth with an eraser n resit it..or replace with a standby n see..

5) a) see if ur hdd is noisy or emitting any 'ticking' noise (like 'tuk tuk' or 'kirr kirr')..
b) or if the system is not supporting either the newly installed device or itz software/driver /firmware
if so, u need either a fresh os installation or ur hdd is likely to b replaced..

6)remove/clean dust neatly..dust is non-uniform in nature n may cause jam/short circuitry/excess resistance n many more..resulting an increase in heat..

7)open the CPU Heat-Sink with fan out of the socket..put some "Heat Sink Compound" (available in local electronics chip level spare market)between the cpu/processor and the CPU Heat Sink *** fan..resit/fit it tightly in position..

8)on main/mother board..see with a debug card for mb error..may b short..look for defective capacitors(espabove1000mfd)/mosfets..go through the mb's south bridge n the circuit lie around atx connector..the crystal clock generator (if cpu isn't heating up)..

9) [in case of desktop] the smps itself may b defective/faulty..check the outputs of smps viz. 0v (black~ground); +12v(yellow); +5v (red, green~ps-on, violet~pg& grey~sb); -12v (blue);-5v(white); +3.3v(orange)..the 'oscillator and error amplifier ic',or pwm switching regulator circuit..look for defective protector-transformer/resistance (esp 4.7k)/mosfet..
check the battery n adapter [main power], in case of laptops..

if u r not a professional, always better to seek advise from ur system admin/vendor....

Possibly, the CRT monitor was set to a frequency which is too high for the LCD monitor.

Try booting in Safe Mode (press F8 at boot), then set the video for a lower resolution.

Reboot with the new, lower, resolution.

In Control Panel choose Hardware, then Scan for New Hardware and get the LCD monitor recognized.

Then, from the Desktop properties, you will be able to see all resolutions supported by the monitor.

L1932TQ Fails on Desktop, works on Notebook
it simply means that your cpu is not giving back signal to your monitor to process, in fact, it is a cpu problem that is why there is nothing to display in your monitor.

Your cpu froze because of that usb thing. the only way to unfreeze it is to manually reset your hardware in this order.

1. RAM modules. If you can unplug your RAM (memory modules) connected in your motherboard, please do it. Just unplug the modules and then plug it back in. if you have 2 rams, then interchange them when plugging it back. this will force your mobo to refresh its resources.

2. CPU. if you can pull out your cpu chip, then do it. this will refresh your cpu setting in your mobo. (mobo = motherboard)

Regards!

if another monitor is available check it on your system and check yours on another. this is the simplest way to eliminate possibilities. could be your video card all together, just not kicking out a signal

No display and LED green blinking, the same problem happened with my LG 700E 17" monitor too. By these solution I changed 2 capacitors of 1000uF 10V, & 16V with same ratings. After this relay and display started with the message check cable, BUT WHEN CONNECTED TO CPU IT AGAIN IN THE SAME STATE WITH NO DISPLAY AND LED BLINKING....next what, should I change 220uF 450V capacitor also or something else is there to do. Thanks for this place for good Ideas.
