Hi, my toahiba satellite m305d s4828 backlight isn't working, i already replaced the lcd inverter but it still didn't work, i dont know what to do anymore

The problem might not be with the LCD inverter. There is a possibility that you have a faulty LCD screen cable. The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board.
Please check this possibility.

My toshiba laptop screen goes white on startup. However, it does work OK with an external monitor. I replaced the lcd screen and still get a white screen. Could the inverter be the problem?

Had same issue, i replaced both the cable and the screen with 2 new screen and cables but still had the issue. my guess is its the connector on the motherboard where you plug in the LCD cable because my webcam dont even work (dont see it in device manager and my cam gets its power from the lcd cable)..

You can probably fix this. Ask someone who can unsolder and solder. You have three bad capacitors in the power supply!

Toshiba P105, backlight dont turn on in my lap

If the LCD, inverter etc works in anothe laptop but not in the original laptop then it looks like a motherboard problem, possibly the power supply to the inverter.

Acer al1716 dont work

When the LCD monitor display flickers and or has a black screen then the fault is usually a faulty inverter or the CCFL lamp. When you look at the screen at a sharp angle and you see a dim image then it is a backlight problem and it is caused by a faulty inverter or a CCFL lamp.

Power problem

Can you do a simple copy and can you do a simple print job? For that you dont need the lcd info.

If yes, you need a new lcd display as a spare part (brother service partner).

If not, the main circuit board needs replacement (This spare part will cost more than a new mfc!)
