Sony BRAVIA KDL-40S2000 40 in. LCD HDTV - Answered Questions & Fixed issues

Replaced circuit board under warranty.

If the line is present in all inputs and modes, there is a problem with the LCD Panel. The only way to fix it is to replace the whole LCD Panel which is very expensive (usually around $1000+ for 40" Sony). Unless the TV in under warranty, it is usually around the same price for a new TV.

You have a problem with power supply take it to a television engineer

check to be sure your remote is sending IR signal, with a smart phone camera hold remote IR eye in front of camera and click any buttons on remote, you should see a light coming from IR eye. If no light emitting, remote needs to be replaced.

Check your cables first to see if they are causing it. Faulty cables can cause all sorts of problems. If that doesn't solve it it could either be that the colour settings are wrong, for example NTSC instead of PAL or vice versa. Sometimes it is something to do with copy protection. In some cases counterfeit discs, or faulty discs. And in some cases a fault on the DVD player.

To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset.

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board.

Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

If your TV seems to be darker than you think it should be, it is possible that the problem is with the light sensor. The light sensor will automatically adjust the picture brightness based on the ambient light that is in the room, (i.e. if the room is bright the picture will also be bright, if it is dark the picture will also be dark). To turn this feature off go to Settings > General Setup > Light Sensor.

Had the same problem. The infrared receiver quit working. Could not use the factory remote or the cable remote. Simple fix- I just cleaned the infrared receiver. Both remotes now working.

Yes, as long as the source material has subtitles. Roku Closed Captioning Help

Thats a pixel data problem, there's no data being sent to that row of pixels so they don't change color. This is a pixel address registry (PAR) issue and the PAR circuits need to be serviced its usually due to open or shorted SMT components on the PAR circuits. PAR also sends data, voltage, and control to each pixel, the green line you see are pixels that have voltage but because there's no data sent too them their all green because there's no control. If the pixels have voltage but no data or control they show up as green red, blue, yellow, or whit line vertically down the LCD panel. The vertical-horizontal section of PAR are controlled by 16 to 32 bit micro-controllers which may need replacing. If its under warranty take it back if not have your local repair center fix the tv for you...

The T-CON is the first thing I'd repair/replace. Well, maybe after checking the inverters, but that's a bit harder to do than to replace and see if it works.

Hello, There are 2 small 1.5" fans that are located on the top right and left sides of the screen. These fans are of the non ball bearing type, so the bearings may be wearing out. You can either replace the fan or add a couple drops of oil to it. Remove the label on the back of the fan and put the oil there, it should quiet down. This will work for a while but eventually the fan will need to be replaced. Good Luck! Rich Lilja
