Question about Sanyo CLT2054 20 in. EDTV-Ready LCD Television

1 Answer

CLT2054 I have had my TV for about two years. Two days ago a yellow band about 3/4 inch in height has appeared at the bottom of the screen. What would cause this? Can it be corrected?

    Do you think this condition will worsen? I will probably have to buy a new TV wondering how long this one will last.

This set has a history of problems that seem to occur around the two year mark. My own experience with this model is with a defective "Ball Grid Array" IC which has balls of solder under each contact point where the device is surface mounted to the Printed Circuit Board. The disadvantage of BGAs is that they do not have the flexibility that a leaded package has under extreme temperatures and mechanical stress, which means that the solder joints can crack over time, creating oddball symptoms like you are experiencing. The short answer is that the board is not field repairable and a replacement board is not available that I know of.

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.

I have a 2 inch black band which appears intermittently dwon the full height of a 22inch JVC lcd television can anyone explain it for me? thanks


If it is black vertical band from the top all the way down to the bottom of the screen, your LCD panel is going bad and you will see more bands and it will get worst.
