The set will need to be properly diagnosed to narrow down the problem. You could be looking at a bad inverter, bad CCFL lamp, fault in power supply or main board.

hi, since your TV is under warranty,It is better to ask for a replacement a new one ..the problem is factory defect.

It probably has dying power supply due to bad DC filter caps, see pictures of fails VIEWSONIC due to bad caps at my Photobucket.com.

Hi, Mary with Dish Network Customer Service. When the picture alternately goes from normal to a black screen, it is an indication of an intermitten signal issue. You can attempt to reset the receiver box by unplugging it from the power for 10 seconds and letting it reboot. Hopefully this will resolve your issue.

check your capacitors cp150 114 120 if any of them is puffed up on top it is bad replace all 3 cap. 2200uf 1`6v and two 220uf 35v. also resolder FBT pinns.

You need to get this tv service asap.i beleive that the problem is in the inverter board or yb board.


good luck

I had a similar problem, mine was a bad earth connection on the main (tv input) board. it earths through the screw mountings so check they are screwed in nice and tight, probably best to remove and then refit it.

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
