Connected to "Y"? That is for the rgb cables for a high def connection method. You need to find the video in connection plug, usually yellow to get a color picture for the games. Hope this helps.

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

The backlight is problem is caused by either a faulty inverter board or a faulty CCFL lamp.

81@hI have a LA32B550KIF LCD TV by Samsung. Just recently the picture has gone but we still have sound. Is there a step by step manual that I can follow online to reset the settings? I have currently...

Hello destinee81, let me help you.
I often see things like that, mostly occurs because the problem panel.
To ensure it, first turn tv on than wait a minute until you hear a sound from a channel tv.
After you hear a sound and still no pict, knock gently the panel with your hand ( not too hard but not too soft). If you see a flashing light (on area you knocked) , that mean back light panel is OK. Open rear cover , there are 2 boards (Power board and Main board) and 2 board attached on panel (inverter and T-con) , "beware with high voltage on power an inverter board". Check connection on t-con and main board, clean it with brush to remove dusts on it. if still make no changes , replace the t-con board.

Second, repeat first step above. If there are no flashing light on knocking area,. that problem from inverter board. Replace it. If any problem and questions, please let me know.
I hope that will help you. Thanks.

Samsung LTN226W 22 in....

I'll go through the basics that you can try yourself. It might be a problem with the backlighting, which usualy is very cheap to fix - take a flash light, dim the lights in the room and flash the light into the screen to see if theres any picture visible. If so then you're looking at a backlight or backlight inverter failure, like I said, cheap. second(or first) thing to try is changing the cables you have the TV connected with, they might not be seated well, or have some other problem. For a tutorial on changing the inverter click here: http://www.lcdpart.com/doc/inverter_installation.html BUT - have a warranty? don't touch it and take it back to the shop. Good luck
