If the model is not listed correctly let me know with the make a comment button on this page---KDL-40S2400 IS A LCD SET---usually on that model on turn on you may hear a high pitched buzz which is a issue with something on the power board making a sound---

If model is a KV type it is another issue.

Good day!

That problem is called close caption..

please go to the menu using your remote then go to the settings and find close caption text..

after you find the close caption please turn it off after go back to the TV mode then see if the problem is still there..

If the problem is still there just add a comment to give you another solution..]

NOTE: this solution is based on my actual experience before on my TV...

thank you and good luck.

Tv turn on now,have picture flashes only a few sec. than dies than sound left only?Yes,than those 2 long board call the LCD inverter boards are dead.These 2 long LCD inverter boards job are to help the LCD screen panel to have a backlight to produce a picture.Tries websites like Shopjimmy.com,Ebay.com to buy those 2 long refurbishes LCD inverter boards for the replacement.

Sony BRAVIA... | Answered on Dec 08, 2010

The backlighting is composed of 2 elements : the inverter boards that take the low voltage from the power source and transform it in the high tension , and the CCFL tubes that convert that tension into light. The tubes extremely rarely fail, so you must refer to the inverter boards.
To replace then you do just like for every other board: you take the back cover off, you locate the board, unhook all the wires and connectors, unscrew the supports and take it out. The fitting is the opposite.
Unfortunately Sony refuses to allow other companies or sites to sell new replacement parts for its products so either you look for it on sites like Ebay for second-hand/used ones or you order anew one directly to them
It will cost you around $400, shipping included

this appears to be an LCD if the model is right. If so then i hope u have extended warranty because what you have is a bad screen. something has caused the layers to separate, either a cleaning solution you used of just a plain unlucky. but to get rid of it replace the LCD Panel which is not cheap. Good luck. PS dont use any kind of cleaning solution it ruins the screens

Just respect the colors. Green output from the dvd to green input tv, Red output from the dvd to red input tv and the same with blue. All 3 cables (green , red, blue) are for the picture, so you got to plug another 2 for the sound.

Hi Sherry, you can test your remote control to see if all the keys work correctly
Take your cell phone, put in camera mode and point the emitting LED of the remote control towards the camera,
press the keys, one at a time and see if the emitting LED is illuminated, if so, try the volume up key, if the light does not turn on, you could carefully disassemble the remote control and clean the contacts and the keyboard internally rubber,
Do not use alcohol to clean
the rubber keyboard, you can clean it with warm water and detergent then let it dry very well,
the contact plate, you can use a cloth with some liquid to clean the glass,
the idea is to remove the rubber residue on the contacts
then arm again and test, but you have results consult a specialized technical service
I hope you find the suggestion useful
Greetings Franco Dosil

Hola Sherry, puedes probar tu control remoto para saber si todas la teclas funcionan correctamente
Toma tu celular, pon en modo camara y apunta el Led emisor del control remoto hacia la camara,
presiona las teclas, una por vez y fijate si se ilumina el Led emisor, si es asi, prueba la tecla de subir el volumen, si no se prende la luz, podrias desarmar con cuidado el control remoto y limpiar internamente los contacto y el teclado de goma,
No Uses Alcohol para limpiar
el teclado de goma, lo puedes limpiar con agua tibia y detergente luego dejalo secar muy bien,
la placa de los contactos, puedes usar un pa?o con un poco de liquido para limpiar los vidrios,
la idea es sacar el residuo de goma que hay sobre los contactos
luego arma nuevamente y prueba, sino tienes resultados consulta a un servicio tecnico especializado
Espero te resulte util la sugerencia
Saludos Franco Dosil
