LG 42PC1D-EC Plasma TV wont switch on

[rolyh]

Hi, I have a fault with a LG 42PC1D-EC Plasma TV.
The TV won’t switch on. At switch on the front Led display will change from red to flashing blue then returns to red and there is a click sound when the led turns from red to blue.
I have replaced all bulging capacitors 9 3300uf and 2 680uf. But the problem is still the same.
I work in electronics so and a PSU circuit would be helpful, the PSU p/n is 68719PT299.
But any body experienced this fault.
