HI ITS TUCH SWITCHES ARE DOING PROBLUM PLEASE REMOVE THE JACK FROM TUCH SWITCH BOARD AND THEN TRY IT WILL WORKING FINE M NASIR

Hi dear its main board problem and some time LVDS FFC cable problem . thanks M Nasir

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. https://homenol.blogspot.com/ https://elektrotricks.blogspot.com/ http://electronicshelponline.blogspot.com/ Blinking codes details to many popular brand TVs are given. If blinks continue without any pause, the main board is faulty. Search the sites by type in the brand name of your set, in its search box at the right column. View it on a desktop or in web View by mobile. Mobile view has no search box.

THe antenna came of. Did you use it and is it giving troubles now? If not, then don't mind and leave it.

hello after factory resetting remove all your personal and you can re setting there. thanks M Nasir

It sounds that the fault is with its main digital board. A start signal should come to the P/S board, from the main board, after the set is powered ON. Check whether this voltage comes to it. Refer to its repair manual for details. To get some details, http://electronicshelponline.blogspot.com/Pull up older posts.

Look very like the screen fault. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ https://elektrotricks.blogspot.com/ Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.

You can unplug it for a while, but probably worn out and cheaper to buy new at walmart.

Wi-Fi Protected Setup (WPS) is a standard for easy and secure wireless network set up and connections. Some of NETGEAR's products use the name Push 'n' Connect for WPS. To use WPS, your product must support WPS and be compatible with WPA security. WPS can automatically set up a random network name (SSID) and strong WPA wireless security for wireless routers, access points, computers, adapters, Wi-Fi phones, and other electronic devices. WPS lets you use a push button or enter a personal identification number (PIN) instead of manually entering a network name (SSID) and password:

• Push button. The WPS button is either a button on the product or a an option on the wizard or utility screen.

No signal is being detected at the air/cable input terminal.

backlight problem

Hi!

First let's be sure that video signal is coming out of your laptop. You did nor mention your laptop make/model and the connection cable type you are using between laptop and TV (VGA or HDMI or S-Video ). I'll assume it is a common VGA cable.
Now, on every laptop the user can choose where the image is displayed: on the laptop only, on the external monitor/TV/projector or on both displays. This can be done by pressing the Fn key toghether with one of the F1 to F12 keys. Usualy it is Fn and F5, but other laptops use other key instead of F5. (please check the icons on your Fx keys, there must be something like two displays side by side). Each time the keys combination is pressed, the image switches between the 3 positions: only laptop, only external, or both displays.

Please let me know if it helped.

If you are using something else than VGA cable, please post again also mentioning what type of laptop you have.


Regards,

Bogdan

Try this website, they rebuild Printed circuit boards: http://www.moduslinkptstvboards.com/tv-parts-repair-and-return/

Hi Darryl mclellan, because of the amount of flashes, it is very possible failure in the system of LEDs of back lighting or the circuit that feeds it

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

the capacitors on the power supply are bad they mushroom out at the top of the capacitor replace all caps with gold rated or silver rated high speed capacitors that can discharge at the much higher frequency generated by the power supply I use a higher voltage and I have noticed caps that have 12 volts applied to them and the caps are rated for 10 volts, because of the caps being under rated voltage wise the caps will work for a time then from over heating of the caps they will mushroom the top of the caps I have been repairing televisions for 47 years of my life since they had tubes in them, the caps with a black stripe or white stripe are not rated for 15,000 khz these caps sold at Radio Shack are only rated for 30 cycles the frequency of all switch mode power supplies is much much higher than that of a capacitor run by a power transformer, thank GOD that transformer has been replaced by switch mode power supplies that use the PWM technology much more efficient and effective Only use the gold or silver rated high speed caps to replace all caps throughout the HD TV and you can then sign your name to the invoice as being "repaired" I know exactly how PWM switch mode power supplies work you have to work with them from the secondary to the primary and I have repaired 1000'2 of these units not only for TV but printers, UPS, audio power amps, any thing with a PWM switch mode power supplies.. And I am a Certified Electronics Technician/Engineer.

moved you out of PC to TV ok? go to sony.com and buy the service manual>? ?

In most of the case, the main board is defective.
