zenith z50pj240 problem

[KevinCro]

Hello, I have a zenith z50pj240 that I cannot get to power up. I replaced the power supply and y sustain board. When I plugged it up with the new y sustain board, something caused an arc in the power connector to the z sustain board. Now the tv goes back to the original clicking noise from the power supply and a red light on the front. I thought I had the problem narrowed down to the y sustain board but apparently the actual cause of the problem is what fried the y sustain to begin with. Any ideas?

Also, the power surge did not blow any fuses anywhere in the system.

I tested them and they check good. No meter beeps indicating shorts.
