This is a common problem on these plasma TV's. The problem resides in the high voltage boards known as the X and Y Sustain boards.. You can purchase them here for a very reasonable price:

The above link is to a Y-SUS board. The X-Sus board is often the 2nd cause of failure and can be found here:

To test which board is failing, you need to check voltage input to the YSUS board first... Input should be 120V from Power supply, output should be above 250V.. Do this test with XSUS disconnected. IF 250+V exists, then XSUS is damaged. If not, then the YSUS is the faulty part.

I know it's rather late to post this but just thought I'd post anyway, maybe you still need the help. If you get no sound and no picture but yet an amber light (yellow) also if you heard a pop sound from one of the fuses, there is a good chance that you YSUS board has take a turn for the worst. There are kits that you can purchase for $200+/- that will get you back up and going....for 5 more years.

On my Zenith Plasma model #Z42PX2D, when we turn the power on (via remote or manually), a yellow light flashes then stays a solid yellow. No sound, no picture, no green solid light like we used to get. ...

i am going to make a guess here , so if i am wrong please do not rate me low . it will hurt me . : my guess is you do not have electronic tools or electronic training ? if not theres not a lot you can do , the light on yellow says when the set checked itself out something is wrong . it will need a board or two .but you need the test equipment to go through the set and find out why . i never guess . if you guess your wrong more than your right and the boards in this set are big bucks rangeing from 80.00 to over 700.00 . so i never guess , and you should not eather . if you have a scope and trvm and know how to use them , great , i can help you troubleshoot . just let me know
