Black screen on Zenith plasma tv's

Zenith 42''model P42W34: The main power board is producing the correct power, the Z SUS board #6871QZH030A has 2 bad 250v 680uf electrolytic radial 105 deg C capacitors and the Y SUS board #6871QYH027A has 2 of the same value caps that are bad. I priced the 4 caps for $20, they have a 2000 hr rating(seems short). Has anyone benn successful replacing these caps?
Zenith 50'' model Z50PX2D: The main board #E247691 has 3 bad capacitors. Two are 450v 330uf and the other is a 250v 820uf electrolytic radial 105 deg capacitor.I priced these at $18.
Is it the short cap life that causes failures? These tv's are only a few(1.5 &3) years old. All 3 boards are $500.

    Stays on for uncertain short period then powers off. Have replaced all electrolytic caps. Cannot access engineer mode to reset lamp fault if one exists.

My 42" Zenith plasma flat panel television model


You can check the va, vs adjustment, but alot of plasmas does this, my first thought would be the y sus board, it also could be the panel which is not worth fixing, if it is really bad, check voltage and if this isn't out then Y- board is the next thing to check.

I have 3 black stripes on my Zenith 42


Turn off the TV then unplug it. Disconnect the cable connection and clean the terminals. If the stripes still exist, you have a bad TCP (tape carrier package). It is responsible in transmitting color information to the display panel from the X-Drive (A-Bus) Board. This is not an easy repair. Service of an experienced or a qualified technician is recommended.

Zenith p42w34 will not turn on


Before Opening, double check something for me and post a follow up. I have this tv and I believe it has dual power buttons. One main and one secondary. A remote can't turn it on unless the main power button on the bottom left is on. 
Please post follow up.
