LED driver is the most common cause. You should be able to get replacement parts from www.tvcircuitboards.com they can assist with troubleshooting why the LEDs are not lighting

SOURCE: Dark horizontal lines on Sony KLV-26HG2 LCD TV screen

Hello,

If you can fix it by yourself, there is a problem in horizontal circuit panel, you need to check that in series because the part appear visbly good but when tested by the exact tester you register busted. that should be replaced immediately. Check also the vertical panel parts of the circuit. but if hard you do the job you may consult the service center of your TV or the vendor of the TV.

ps. please don't rate me if you are not convince of my suggestion.

best regards, melnavz

SOURCE: Sony Bravia - picture don't fit the screen

I have a Scientific Atlanta cable box w/ Time Warner. I followed the instructions below for the cable box. Somehow it reset my picture and I can now read the ticker at the bottom of the screen and the different picture sizes seem to work properly. Good Luck.

Sony klv-42ex410 blink 6 times


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. Viewing it in "Mosaic" or "Magazine" will make surf easy.

That sounds like a defective LCD panel tab, Sony's and Samsungs are notorious for this problem. Does the problem go away when the set warms up or when you tap the screen?

Hi, i have replaced the faulty power supply but now the leds don't do anything anymore. The screen is active but stays black. The backlights are on. When i plug the tv into the mains i also can hear...


If the T-CON board is dead,you will see black screen (no picture) but you will see slight glow due the backlights is still on. Check the fuse and voltage on the T-CON board, dead main board will not be sending the voltage to the T-CON board.

But you are saying taht you cannot get any button on the TV to work, that will point the problem to be in the main board.

You will need service manual to really go in-depth troubleshooting.

Sony KLV-40U100M Screen replacement


If this were just about any other brand, you'd likely be able to find another brand of TV with the same size screen and swap the inverter boards and the LVDS board. The problem with Sony is that the company uses internal designations. If you have homeowner's or renter's insurance, it might cover some of the cost. Otherwise, put the damaged set on eBay (you'll get a couple hundred dollars plus shipping) and go buy a new set. Likely, any larger set for sale with a good screen is going to go for more on eBay and finding one is rare.

It was working fine then no picture dark sceen sound work fine


More information is required. Your backlight is lit (screen not dark) but I need to know what you have connected to the TV (your sources) and how they are connected. Does the menu/OSD (on screen display) work?

OK SOUND NO PICTURE


More information is required. What do you have hooked up to the TV and how is it connected? Do you have a menu/OSD (on screen display)?

TV SWITCHES OFF


Very likely a power supply problem.
Most modern sets monitor power supply performance continuously and if a higher drain circuit is drawing excessive juice, they are designed to shut down to avoid burning down your house.
After all, no house, no new TV needed -

I would be sniffing around the top vents on the set to detect possible 'hot' odors coming from it.
