Audio, no video, black screen but can see with flashlight in dark room. The input will show for a second before it goes black when turned on.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced.

My home screen comes on then it goes to a white screen


It means the screen inverter and or the screen itself (is) are dying. The inverter's price is cheap, so you can buy a screen replacement and an inverter board at the same time. eBay.com is a good source.

Toshiba Regza 47wlt66 has sound but no picture


Hi.

If you have picture but no sound and problem is not cable settings or source selection, then the faulty part is usually the inverter.

Firs test the TV. Check if there is on screen display (the menu). If OSD is displayed, then the problem is either cable/source settings or a defective input circuit. Try also disconnecting power cord for ten minutes and then up to one hour. Power drain may fix temporary faults.

If all that does not work, then the problem is either inverter or power board. In some case the main controller board may also be responsible.

The inverter is a power board that converts DC voltage from PSU into AC high voltage, powering the whole backlight system. When there is a problem with the inverter the whole screen will be completely dark, while the sound keeps going on.
A problem with the inverter will mean that either inverter is bad, power supply is bad and does not power the inverter, or main board is bad and does not turn inverter on. Those are the three parts that must be tested when the inverter does not fire up ( sound and dark screen). Here broad description of how to test the three parts: Before proceeding...

From a user level point of view, all you should do is disconnecting power cord for fifteen minutes, and testing the TV with different connected devices and different cables (e.g. with a DVD, a receiver box, using a SCART and using HDMI).
Disconnecting power will allow a power reset that sometimes can fix temporary problems (usually not sound but no picture).
Testing different cables and devices excludes the chance of the problem being given by a bad connection.

If that does not work, call the manufacturer at the number listed in the owners manual. Verify warranty status (warranty may have expired 09/10). Make present to the operator that the TV is just out of warranty, and that the fault occurred without you making any wrong use of the TV. Some manufacturer in some case apply special condition.

I cant see any thing in my display but all are working starting sound of windows xp brightness function working but some time its works


1. Test using an external monitor. If it works, then either the screen bulb or the inverter board might be defective.
2. Test the inverter. Easiest way to do it if you have a good screen with a good bulb. Connect the good screen to the inverter board & test it. If it lights up, then the inverter board is good. If it did not, then the inverter board is bad & needs to be replaced.
3. If the inverter board is good, then we are left with the possibility that the screen bulb is bad. To fix this, we will need to replace the LCD screen.

I turn on my computer but the screen is still black


think you might have a failed screen inverter (FL inverter); this problem is very common with laptops. The inverter board acts as a power supply for the LCD screen backlight bulb, it converts low voltage DC power into high voltage AC. On most laptops the inverter board is located inside the display assembly below the LCD screen and you can get access to it if you remove the screen bezel (LCD mask). When the screen inverter goes bad the backlight will not turn on anymore or it turns on for a short time and then goes off, but you still can see a faint image on the screen and the external monitor works just fine. First of all I would make sure it’s not just a loose connection and reseat connectors on the inverter (it looks like you already done this part). Next, I would try replacing the inverter board. It might fix your problem with the backlight. It’s possible that you have a faulty cable, bad motherboard or even bad LCD screen, but I would try replacing the screen inverter first.

My laptop picture will work for a while then the picture wont come back on when you turn it back on sometimes its fine fir days and sometimes it takes days weeks for it to show


Sounds like a loose connection between the backlight and the inverter - or a faulty inverter. Inverters generate and store high voltage (even when off), so be careful if you try to replace it yourself.

If you have already tried the usual brightness and contrast controls, the problem most likely is a bad inverter. You can find an inverter for around 10.00 on ebay.
