I got a TV with black screen but I can listen the sound I fixed the TV thanks to plainbill the last time I put a thread with a Vizio 42" black screen pdp42x3 and bill help me to detect the problem and I did the same with this TV ((I bought a new Zenith 6871qzh053b board)). The board has two fuses an one was blow .Bill told me A blown fuse confirms it. A common failure of these boards is the hybrid (under the big heat sink). A new hybrid can be had for about $40 if you are skilled at desoldering. For those of us with lesser abilities, replacement boards are available for under $80, including shipping
Thank you plainbill
