SOURCE: i have sony klv-46ex400, the voume is maximum, it cant reduce either by the remote nor by the buttons, what should i do?

I have a standard answer here for this--read it carefully.

Keyboard issues and answers:A problem that is more common than most people think is an issue with buttons on thecontrol keyboards of modern TV sets.Recently for whatever reason I have seen more questions about this so I have composed this answer and solution for these kinds of problems.It can be any button on the set-channel up/down or volume up down-you name it.The symptoms are the same: channel will scan up or down and will not stop-remote control has no effect on this---It can be channel, volume, or even input or menu if the set has those up front or on the side of the set.All these push controls have something in common-beneath each is a tiny momentary push switch-when pushed with the plastic button it performs a specific task (vol up or down etc.).What happens is the afflicted switch beneath the plastic button is bad-when released it issupposed to stop its function but does not.Keyboard or button controlled features have PRIORITY over the remote control, hence the remote will not stop this from happening. Both the remote and the keyboard go to the microprocessor in the se t but the keyboard is first in line.How to resolve this issue?Someone needs to get at the tiny pc board with the buttons and locate the one associated with the issue (ie sound or channel etc) and unsolder that switch from the board-usually just two pins (may be more for mounting only purposes) and then see if set does not have the issue withswitch out of the circuit.For the TECH minded with the board out test here the switches with a ohm meter set to highresistance-any reading with button not pressed means a bad switch-seen ones that read 5,000 plus ohms-it may be necessary to unsolder more than one switch to locate the offender here but an open reading with switch not pressed is the rule.I have taken the time to compose this answer as some do not understand what is happening in these types of situations---No magic wand or smoke and mirrors here-have to disable the offending switch to know.The beauty (in my view) of this kind of problem is if found, you really do not have to replaceany part-just operate the set with the remote with one button that no longer functions on theset itself-who could ask for more?

How do you turn off TV?

Press the Power button on the remote control once, when the set it powered up. It will power OFF. If you want to power down totally, just switch off the main power at its panel.

Sony bravia lcd won't power on after lightning strike

I am sure the tv is shot from the surge but you can check a few things. I would take the tv apart and test the power supply first. Look for obvious burn damage throughout the boards. If there is a blackened one (prob video board) then you can try to replace that. Don't worry about taking this apart and breaking it further. In this case it can only get better for you.

Hello, I have a Sony Bravia KDL-46EX400 and after an incident the HDMI ports doesn't work anymore. I have checked the other ports (D-Sub / AV / Component) and they work OK, even the USB can reproduce 1080p...

There will be a damaged interface IC on the input board. It may be worth taking a look and ordering one if you are competant with desoldering etc or just order a complete input board.
Hope that helps.
