    Monitor repair

    Anyone here ever fixed LCD monitors? I have an Acer P244w, and the image just turns off for a second or two periodically. Recently, I've started having a problem where I can't turn the thing on at all. I have to wait a little bit, and then it will turn on again. I was wondering if it's a simple matter of replacing something like a backlight.

    Somehow I didn't see this thread. Yes I have fixed them. I don't know how tell if its the cold cathode tube or the voltage inverter other than by swapping parts out. The inverters are device specific(each with their special plugs etc) but the tubes can be moved around if they fit.

    Though monitor can be had for $5 at garage sales so prolly not worth it these days.
    Stand clear of the closing doors, please.

    LCD screens have cathode tubes?

    Yeah are on the edges mostly on the top and bottom but sometimes on the sides- if they're not a wide screen. They are about an eighth of an inch thick or 3 mm. They use acrylic, diffusers and bright white plastic to make the light uniform on the screen. Occasionally only one tube will go bad and you can see the only the top is lit or one of the sides. I would think if the whole back-light is going bad then it would be the inverter that is to blame.
