20 Most Recent LG Studioworks 563N 15" CRT Monitor Questions & Answers

Have you tried another monitor to see if the computer is working?

Here's some tricks I would try. Something here, might help... 1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor. 2. Verify the monitor cable is firmly connected to the computer and the monitor. 3. Verify that you have turned the monitor power switch on. 4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works). 5. If the power light on the monitor is not on, try a different power cord. 6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced. 7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers. Good luck.

Id try a different monitor to start with. What program are you using when it blanks out?

Make sure that all of your cables are plugged in properly. Sounds stupid but I suggest unplugging every cable you can see, plug them back in firmly and try again. Also make sure that there are no USB's plugged in, or discs in the disc drive as your computer may be attempting to boot from these and failing.

Posibile the flyback is spoilt. It is not worth to fix it since it is aging. Buy a new one.

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....

shoot it with a shot gun. get a new one.

first disconnect the path of EHT then check voltages if present then open H o/p transistor check it if faulty then replace it if not then EHT is faulty replace it also check IRF630 mosfet if faulty replace it

manage your frequency upto 60 Hz.....
and do not interfere with graphic properties

may be the problem with the output transistor

Hi, It could be you need a new V-card. or your monitor is on its way out. My bets are on the monitor. Good luck.
