We are having issues with the screen. The display

Sounds like a defective T-Con board, but it is better to test it before replacement. Also there is a possibility to repair it at a lower price. You can find a company that is testing this kind of T-Con boards and repair them here: http://www.coppelltvrepair.com/p/540/repair-service-for-auo-t400hw01-v5-40to2-c06-40t02-c06-lcd-timing-controller-t-con-causing-bad-tv-picture

Blank screen

The fault is with its main power supply regulator section itself. One or more voltage rail is missing. Your TV need a through checkup. Seek tech assistance.

Kdl-40v4150 turn on only 1 min then going black

That's either bad power board or bad main board.

Given the description it is very hard to say which of the two it is.

Frankly, considering you can get a new power board for $25 I think you should just go ahead and do it - it will cost less than bringing the TV to a repairman and as a repairman I can tell you they wouldn't have much better chance than you do...just shoot for a try and this will narrow it down to a single board.

I am not anyhow associated with the above seller. it is just the lowest I could find on eBay.

Hope this helps!

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)
