Question about Samsung HCN4226W 42" Rear Projection HDTV-Ready Television

Open Question

I have a samsung 32 inch flat panel TV that is about 1 year old. While we were watching TV tonight, the screen just went black. We could still hear the audio, but there was no picture. I checked to see if it was the cable signal by trying to play a DVD, but the same result - we could hear the audio, but just a black screen. All cable hook ups in the rear seem ok.

The screen has colored vertical lines and becomes to a dark black band about 6 inches of width.The tv is exactly two years old by today.


My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display problem (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further solution updates will be on my Facebook page.

Lines down screen


We have a Samsung LE32A457, whilst we were watching T.V tonight the top halve of the screen suddenly appeared with green lines halfway down the screen and that half of the picture was unwatchable, T.V is 2 years old. We have removed all scart leads but this did not help and the problem still exists, when shutting down a white horizontal line across the centre of the screen appears from this line upwards the picture is faulty. Any help or advice would be grateful.

My 32 inch samsung lcd tv has got faint black lines running down the screen ,its nearly 4 years old but i expected it to last longer than that,and ive had sky hd box recently would that have anything todo...


Are these lines on both side of the screen or what location are they in? They can be caused by watching 4:3 television with the black bars on both sides. Watching 16:9 full screen HD wont cause issues with that. If only on the sides there is not much you can do except put a pure white screen on the TV and leave that on for at least 6 hours. This will age the panel a little but in theroy wil even the pixel burn you have to make the lines less noticable. Please take a few moments to rate my answer. Thank you

32" flat screen that went black


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

My 46-inch Samsung LCD TV screen went black. Audio works.


If you are seeing light then the back light is working. Can you get a menu?Do any of the other video inputs work? If no video but has backlight and no men or any on screen display replace main board.

Blue screen


Did you see the back light at the back. If yes, the problem may come from T-Con board. Try other source like playing DVD AND If THE SAME PROBLEM HAPPEN, you may think of the main board defective.

I had a problem with a Samsung 46 inch LCD and it had audio and dim light but no picture and found out that the logic board toward the top (inside tv) was bad and was no longer available and the only way to fix it was to get the entire display panel (the logic board came with it) It was not costwise to repair. Hope this helps.
