Re: tv went black

I've owned this unit since Dec 2005. It appears there are two Video Amp boards Z & Y-SUS boards, that have failure problems.

After 10 months, my ZSUS board went out and was replaced under warranty. And... Just a month ago, the same problem occured again, so I've complained to Zenith (LG) and they are extending my warranty to repair the unit.

Something short circuit with its circuit board. you must have through knowledge in electronics, and work experience to do repair work to this Plasma TV. As you know, plasma TVs are the latest technology devices, and a mere knowledge in electronics will not help. It will be best to get this set repaired by any experienced service technician or by the authorized service center for Zenith at your town.

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.

The problem is from the menu control board inside the TV. A Ic or transistor might be faulty on the board.

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.
