Sony BRAVIA KDL-46XBR3 46 in. LCD HDTV Questions & Answers
Loses picture and shuts off and on
I once had an HDTV with a similar problem. If I turned it back on, it would make a loud BUZZ-BUZZ-Buzz noise for about twenty seconds before coming back on.
I can only guess that the problem is the TV drawing too much power from a circuit that can't support it. Do you have many electronics plugged into the same socket? Is the TV going into a splitter? Try isolating the connection and the TV might have better luck. No guarantees however.
If it's the same problem I had, then it will do this no matter what you hook up to it, as you seem to have at least partially discovered.
My BRAVIA KDL-46XBR3 shows like a mirror image
many bad lcd panels will show issues like this
check the menus and if theyre bad its likely a bad lcd panel
i'd complain to sony and see if they are extending the warranty for this issue as some xbr panels were defective

Try this and also read my guide to understand what it takes to make the screen lights up with pictures.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Sony Bravia 46 XBR has the input bar stuck at the top of screen.
Unplug the TV for a while and hopefully, that should reset the circuity. If you're using the original remote control, check for the display button and press it.
I would also suggest doing a factory reset if your TV has that feature and if the TV allows you to do it after unplugging it.
I need to remove the back off a Sony Bravia KD-48X81J
The front and back pieces are like a clam shell and are compression fit with tabs into one another. You need to use something like a guitar pick or spudger to separate the pieces. Dont use metal objects due to damage that will happen to the plastic .
How can I watch Netflix on a tv Sony wega that isn’t hooked to the internet. It’s wirelessly connected to Vizio ( smart tv Netflix built in) but I want to be able to watch in a different room
netflix is a 100% internet web site , streaming site.
thus the net in flix.
what did you mean by hooked?\
do you have internet at home at all?
do other things in home work to the internet, like PC or cell phones.
what I can not under stand is (different room) this phase
implies some rooms do work (netflex)
and wifi gets weak if my move any TV farther from the home router
and will fail past 25 feet or more. wifi is super weak through walls
for sure brick, or 2 walls.
if home is small one wifi access point is all you need
if huge home more.
distance matter, TV to router.
no TV model # told. (tells me wifi spec)
if you said my TV works in room 1 but not room 2, wifi;.
it be super more easy to answer.. is this true?
if true , get a tech to upgrade your wifi.
or go wired, Ethernet.(a better home upgrade)
