    That's what i thought. I'm going to leave your request open to see if one of the t.v. or electronics guys pick it up. a monitor is closer to a tv than a computer

    Did you replace it yourself or did a repair shop do it?

Invertor problem bm49xx


It is easy to replace the inverter, unfortunately it is not easy to replace the back light. It is time to replace the whole screen.

My acer Aspire 3500 wont turn on. It was fine a few hours ago but now wont boot. I keep getting the acer picture featurning the f2 set up and then the screen turns blank with a white flashing - in the left...


if you activity lights on, try connecting to an external monitor or modern flat screen tv. if the screen is flashing then it is probably a screen issue. eg the invertor r screen has failed.

Cracked screen, dented top


I would say just the screen. You may have to bend the metal a little on the edges if needed.

Laptop screen not working


Hi, I'm a laptop technician and if the screen is blank as in there is nothing showing on the screen at all (even when the laptop first starts up), but the laptop sounds like it is starting normally then the backlight or invertor for the laptop screen has probably failed. This is very common.

The easy way to check this is to plug the laptop into a normal PC monitor (if you can) via the monitor out port on the laptop - you may have to press Ctrl + F5 to get a display on the PC screen. If you can get the laptop to show an image on the PC screen then the main laptop itself is fine, and the problem is almost certainly a failed invertor or backlight.

Assuming you *could* see an image on the PC screen, you should then press Ctrl + F5 so that you *can't* see an image on the PC screen any more (this is very important). Next unplug the laptop from the PC monitor (if you did the above) and look VERY closely at the laptop screen. You will hopefully *just* make out a very, very feint and very dark image on the laptop screen. Bear in mind that you may need to re-boot the laptop to get a moving image that you can detect (like the Windows boot up screen for example). If you *can* see a very, very dark and feint image on the screen then the backlight has failed. If the screen is plain bright white or there is no image then the invertor has gone.

The invertor (or inverter as it is sometimes spelt) is a smaller circuit board that sits in the screen housing, the backlight is a very thin "flourescent" kind of tube light that is built into the screen itself. The invertor can be removed and replaced pretty easily by most competent people without much trouble (takes maybe 30-45 minutes to do). The backlight on the other hand is very hard to remove without damaging the screen itself and should only be attempted by a specialist laptop repair company.

Both the invertor and backlight parts are specific to the screen so you must get exactly the same to replace the faulty one with. Online auctions are a good place to get s/hand or new spares, just tap in the *exact* part number or laptop model number and you will usually find someone who has the bit you need.

I hope this helps.

Still having the problem with the LCD screen


Most likely it is the inverter and or the back plain lamps that are failing. In screens where these are replaceable, I always replaced both the lamps and the inverters at the same time. A bad lamp can damage an inverter.
