Hello Cathy, for what you describe, there could be a fault with the LEDs, which illuminate the screen from the back of the LCD panel (backlighting), as the screen does not light up, it seems to you that it does not work, but you do not really see or you do not know in what entrance is the television
I sent a link to a video that explains the problem of the Leds, I also sent you the link to download the user manual
I hope you can solve the problem and you can enjoy your TV
Greetings Franco Dosil
Hola Cathy, por lo que describes, podria haber una falla con los Leds, que iluminan la patalla desde atras del panel LCD(retroiluminacion), al no iluminarse la pantalla, te parece que no funciona, pero realmente no ves o no sabes en que entrada esta el televisor
te envio un link de un video que explica el problema de los Leds, tambien te envio el link para que descargues el manual de usuario
espero que puedas resolver el problema y puedas disfrutar de tu TV
Saludos Franco Dosil

¿C?mo puedo sacar mi modelo Toshiba 52HMX95 del modo de grabaci?n con temporizador? No puedo obtener una imagen en el televisor para el men? de configuraci?n.
¿Hay alguna pieza de repuesto para el n?mero de pieza 4708-K49WDR-A1213K11 - tiras de retroiluminaci?n LED en el modelo de Toshiba TV - 49L621U? ¿D?nde puedo comprarlo en l?nea? Sus aportaciones, sugerencias son muy apreciadas.
Sounds like you have either a bad video card or a bad connection between the laptop and monitor. Hook up an external monitor and if the problem persists, then it is most likely a bad video card.
Suena como que tiene una tarjeta de v?deo malo o una mala conexi?n entre el ordenador port?til y el monitor. Conectar un monitor externo y si el problema persiste, entonces es m?s probable una tarjeta de video mala.
Back-light inverter board fault. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. Surf the site with patience. http://electronicshelponline.blogspot.com/ Pull up older posts there.
ustede debe abril el chasis del TV, y ver el numero del Flyback. o ver el catalogo de repuesto. o llamar a Toshiba de USA, y tenga el numero de parte. Dios le bendiga.
