replace the power supply board

hi:
this problem may be due to a faulty T-Con board, replace the board and the issue should be resolved.

Check its back light inverter board for the fault. This is a skilled work. Contact any experienced service technician to get this set repaired.

You may have to reset the ribbon cables betwen the LCD panel and the T-CON board, very delicate operation if you have never done one and you can easily damage them.
Please read my guide and look at the picture and learn about the symptom of bad T-CON and LCD panel here (apply to any LCD TV):

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.

Toshiba seems to be not supplying it, back-ordered. Sometimes available on eBay.

It can be T-CON board, ribbon cables between the T-CON board and the LCD panel.
