20 Most Recent Sony Bravia Z KDL40Z4100 TV Questions & Answers

If you get this result from multiple inputs (IE HDMI, composite etc) it is likely a defect/failure in the screen. This is not something you will likely be able to fix yourself.
I recommend contacting Sony on how to proceed on getting it fixed. If it is still under warranty they will likely send a tech to look at it or may even send you a replacement.

Bottom line for the extra connectivity and DLNA certification i would go with the
Bravia Z-Series KDL-40Z4100/B 40-Inch 1080pBecause if you connect this to your in home network you can stream music videos and music off you PC onto your TV without the need for extra wired or memory cards etc.

Otherwise if you don't need this feature the other options are identical on the other TV so it is just as good a choice.

Question edited for clarity. Full 'make model (what it is)'. Question moved from Computers to Sony Bravia Television. Sony says is it the same television, just with a larger screen https://www.google.com/search?q=32ex650+vs+40ex650 You could ask Jimmy which is where your parts come from https://www.shopjimmy.com/

KDL-40HX75A / 40EX650 / 32HX75A / 32EX650 / 32EX550 ...

https://www.sony.com > support > res > manuals PDF You can switch between the i-Manual screen and the TV screen. This feature allows you to refer to the instructions in the i-Manual while using your BRAVIA TV.

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.

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 .

Do you get voltage with the main board unhooked?

what plug not told./PC is dead?no it is not a PC it is a television posted to wrong forumnow corrected.is TV set to sleep mode, RTM read the manual on TVare the clicker remote batteries fresh>?

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)

Hello !! what do you mean by you replaced the video card ? mainboard or t-con ? , we need more information

They are usually M6 or M8. You can get them from Home Depot or Sainsbury Homebase..

Sounds like a bad main board, or more specific the EEPROM is bad on the main

Check power supply caps

You can try but I don't think that will help, sounds like power supply issues, open the back and look for bulged caps
