Philips 37PF7320A/37 won't turn on. Error code 14

Philips 37PF7320A/37 won't turn on. Error code 1 long, 4 short (code 14 according to some users on Fixya). The set clicks on then clicks off a second later, and the red LED displays the error code. I replaced the Audio Standboy board, which some users on Fixya suggested was the problem indicated by that code, but that didn't work. The set remains unchanged with the same error code. The new board was from a 37PF7320A/37b with a cracked LCD screen.

My next attack is at the PSU, but that's an expensive part to replace. I have the knowledge and expertise to replace individual components, but I do not have the equipment to test them. There are no leaky or bulging capacitors or obvious burn marks - there is a little bit of carbon buildup on the RCA connectors for the side audio input, but no burnt or blackened components on any of the PCBs.

My question is whether or not the failed componenets are predictable. This post: http://www.fixya.com/support/t2930430-tv_will_not_stay_powers_up and this one: http://www.fixya.com/support/t1738135-philips_lcd both suggest yes. If the failed components are predictable (ie this capacator and that IC), can someone tell me which ones they are so I can replace them?
