Question about ViewSonic VG150 15" LCD Monitor
Hi, For a while, we had to press the tactile switch many times and soon or late, the logic turned on. Then, to avoid this, we left the monitor on all the time. When the computer was turned off, the monitor was turning off but was not really turned off by its switch, the led I think was switching to an idle color, so when turning the computer on, we did not have to face any problem because the monitor was turning on. Now, it is dead. that workaround does not work any more. At a service shop, they told us an IC has to be changed. We do not know which one. Can anybody help on that? Tanks.
Kbzaloka: That is not a solutiom you posted. If you can't help, then don't post anything.
russolini: I'm having the same problem with a monitor on my bench right now. I did fix another problem it had. It seems some of the surface-mount electrolytic capacitors are going bad. I will let you know if I solve this fault too. If anyone has lines going through their display, and the sides look ripped or torn, your pixel clock is not working correctly. Try replacing the 22uF capacitor C46 right above the pixel clock generator IC09. This should smooth out the 3.3V supply for this IC and correct the problem.
