SOURCE: tv will not power up

no reset button ,sorry. The problem you describe is pretty common with this model as its a fault in the horizontal drive circuit or in the main power supply and without the proper service manual as well as the prober tools and equipment this set its not gonna get fixed. there are no panels or user changable boards as it is a solid state set. ptscorp.com could repair this board or exchange it with a referbished board but it would still requir some adjustment that a user may not be able to handle. time to call the pro.. Sorry couldnet help ya more.. Good Luck.

SOURCE: Moved Sony Bravia TV, now will not turn on at all

The warranty on this set should be for 1 year. Return it for warranty service. Unless the set was dropped, moving it should not have effected anything. DO NOT open the set sas that would void the warranty.

SOURCE: my sony bravia tv is flashing red stand by light

Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Sony bravia 46


Switch ON the TV, at least two times, and make sure about how many times do this front LED blinks, at one time switch ON. These blinks are fault indications. From the number of blinks occur, you can get an idea about the faulty section circuit inside the TV. If you wish to know more about the blinking codes and other details http://electronicshelponline.blogspot.com/ try this link. Pull up older posts there by its left side bar. Blinking codes to many brand TVs are given in detail.

My Sony Bravia will play for less than a minute and then reverts to standy. Any suggestions?


Please unplug tv from wall socket for minute or so,, replug back in and turn it On.
If tv still goes to standby itself than its standby light would blink to show an error in somewhere inside tv circuits.
Let me know how many times standby red light blinking? There would be 3 seconds long pause in blinking so count pause to pause to determine problem section.
Thanks.

Hi,
Its fixable problem like power supply board replacement will solve the problem.
Unplug tv from wall socket for couple of minutes, replug back in and turn it On.

My sony bravia tv will not turn on, the light on the bottom comes on but the screen is completely blank. i was watching it two hours earlier and i turned it off myself. than it didnt work when i tried...


Do you have...a dvd player a ps3 a box?

Becouse if you have, you need to change the input and maybe you forget to put it right back.

Imagine you have a ps3, you have to change the input from tv to HDMI right..well if stop play or watcha movie and torn off the LCD...when you came again the next day the LCD starts as HDMI and not as TV.

You need to change the input...

Hope it helps, if the problem persists it´s a malfuncion...

If TV does not remain in standby and turns on itself then power switch on top of it could be defective and power supply board is also suspected. Take off its back cover and unplug top switch connector just to confirm is that cause of On-Off its own. If problem still exist then power supply board has problem and will be replaced. Let me know the results to move forward.
