My LCD broke down and I decided to do something on it myself. The problem is that I have no idea how to fix it. So I searched on the internet and luckily found this helpful forum. I believe there is somebody who knows well about this matter.
Symptom : 1. At the first stage, the monitor's power light LED kept changing from orange to green and then green to orange while my computer was in 'sleep mode'. It showed me a color adjustment screen(stripes of Red, Cyan and Green) when the LED turned green. Normally it used to stay in orange when it got no signal from computer although its power was on. And the problem started when I woke up my computer by shaking the mouse.
2. The power LED started to blink rapidly. The color was green. And I couldn't see anything on my monitor. Sometimes the LED stayed in green not blinking but I could see it slowly gets to blink dimmly again.
I thought there's a problem on capacitors, so I checked everyone of them after buying an analogue tester. From some caps I got no reaction on my tester.
Question :
I tried to order caps. One question I still don't have an answer to is whether the ceramic capacitor on the board is for AC or DC. I know the home electricity is AC but I'm not sure if all the parts on LCD board are for AC.
Since I cannot be sure if it will revive after I change all the suspicous parts, I would like to consult somebody. Will there be anywhere I should consider checking also?
Thank you very much for reading.
