Yes. It is the fault with its back light inverter. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

My toshiba 22cv100u screen is black when I have tv on, i have sound but no picture


your backlight may be out....I working on one with same problem...the transformer on the backlight inverter board went bad, its about 12 dollars on ebay....but in your case, would require some troubleshooting to determine if you have the same problem. there is an access panel on the back of the tv, under that is 4 connectors, they are high voltage out to the backlight lamps. you would need a volt meter to determine if the lamps are bad or the board

When you turn it on tv screen turns blue then black


If it stays black and you have sound I would guess your backlight is bad and needs replacing.

Had the LCD TV For 5 Years, no problems, then just before going to bed i was about to turn off the tv when the screen went black but sound was fine. I switched channels and you could hear the channels...


Your problem can be related to either LCD backlight inverter failure or T-con board failure. Please turn on your tv, darken the room and see if you notice a dull glow on the screen. If you see a dull glow then backlight is functional and the t-con is dead. Otherwise it can be a backlight inverter failure(in some cases the backlight itself). In that case I would try replacing the backlight inverter board and hope its not the backlight as the backlight is embedded into the the panel and the only way to replace it is to replace the panel.

My LCD HDTV screen keeps going black.


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
