Philips 60pp9202 power issue

We have a 60" Philips 60PP9202 that about 3-4 months ago we had the red convergence chips replaced, I think that is part # STK392-120. At that time the red wouldn't align, we had them fixed and everything was fine.

 The other day the TV wouldn't power on, Philips said to unplugg it hold down the power button and plug it back in, it worked for about two days.

 Yesterday went to turn it on and it trys to power up, you can hear it clicking and the power ligt illuminates.

I was told the chips on the red converegence could be bad again....is this possible?

 Is there a heavier duty chip I can replace them with?

 How hard are these to repair? Is there much sodering? I am am electro/mechanical engineer and would like to save some money this time, but don't want to screw it up anymore.

 Thanks for your help
