Polaroid tda 03211c problem

[cue]

I have a polaroid TDA-03211c LCD TV with an IPOS 150 REV. 1.8 Power Supply board, the LCD is black, the power turns on but I have no backlight, I have checked the capcitors on the power board, all of them look good except for the big filter cap (150uf 450v) which I have just noticed is domed pretty good. The LED in the lower left corner of the board is flashing red when the power is turned on and stays off when the power is off. Anyone have any ideas?
Here's how the 150uf 450v looks like

The 'Net is full of spare parts for your TV. You can get major ones for under $100. Does your TV costs that much? You can get similar new one for $150, probably.
