How do i set convergence of red,green ,blue through service mode

Most common cause for this on the Sony KDL 40EX520 is that the connections to the screen across the top edge of the panel become loose causing blurred picture, mis-aligned colors etc. The Fix requires dis-assembly (Removal of the entire case) and re-seating/resecuring the connection across the top of the LCD Panel. There is a pretty detailed video of the process (less the disassembly) here: https://www.youtube.com/watch?v=80PfZXFGDvQ

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)
