Toshiba lcd screen really dark

Since the picture died slowly i suspect a capacitor on the powersupply board,if the screen flashes then goes black and sound is ok
could be the inverter board that drives the lamps.

Replace it with a new LCD Inverter, you can address the following issues:
Screen image, but the power light stays in
Dark display, but still readable
Flashing on and off of the screen between 1/2 to several seconds
The power indicator stays on, but no display and sound
Screen images, but LCD TV still has sound
Picture cycle on and off, as well as high-power LED lights

Hi,

Hello,

I believe the power led button is still on while the screen goes dark, if yes, it means the picture board of your monitor is bad that is why it appears for a second and goes dark after that

Since the power led button is on, It means the picture board on your monitor is faulty that is why it appears for a second and goes dark.

The best thing for you to do now is to take the monitor to a local repairer or any service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself in other to complicate issues.

Take care.

Sounds like an LCD backlight failure, looks like you'll need to replace the LCD about $100 on EBay

Holding the power button down for 10 seconds fixed this problem on my Regza 47"

Hi MG86,

Most PS2 games are dark and auto brightness controls will casue your LCD tv to brighten up automatically in response the dark video coming from PS2 games. I suggest you get into the menu settings of your TV and find a setting that will shut off the auto picture controls.

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

Next time it goes dark do a flash light test to see if your inverter board is fubar.
