SHUTS OFF AS SOON AS YOU SWITCH ON


Possible short in the main board, possible in the display drive power. The set triggers ON but the error makes it trip off due to the fault. So disconnect the main power to the driver IC -and check, make sure that all the leads on the board are having good contact- NO DRY SOLDER.

Apple Cinema HD Display 30'' black screen, power light blinking


I don't know what might have happened, but a number of years ago I had an apple monitor and the power light on it started blinking, so I got in touch with apple and they told me that it's flashing an error code, so they told me what the blinking indicated and fixed it.

So I think the blinking of the power light on your monitor could be indicating an error code so I suggest you call apple and they will identify what the error is indicating.

Monitor will not power up. was working fine last night, and now is not working at all. Just black screen.


very incomplete thread..i gotta know 1st what is ur system configuration..is all ur system is getting power on..is there any light on cabinet glowing (the power n hdd)..is there is power light coming on ur monitor..is there any sound coming out of the system..or the set is dead..??..

considering that the system gets on but u get no display and assuming that the bios has not been flashed in a wrong way & u r a professional..

however, before u proceed to complex checkups..check the mains power supply- the fuse/switch/wirings/power cords/other associate circuits..

probably itz either minor case of loose ram/improper ground/cmos battery..
or major case of faulty or defective smps/cpu/main board short/display adapter or card/monitor

..plz do check the following as in order:..

1) 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..

2) if u hv a graphics card, replace with a standby or onboard and see..

3) 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..

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

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

6) 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..

7) 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..

8) if itz not the smps, then it must b ur main/mother board..see with a debug card for mb error..may b short..look for defective capacitors(esp above 1000mfd)/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)....

always better to seek advise from ur system admin/vendor....
