Same issue as previous poster...
I was watching tv then all of a sudden, a sound simalar to something being "electricuted" and the tv screen went blank. Now when I press the power button, all u hear is a rapid clicking sound in the back and the tv wont turn on.
My TV is 2 years and 6 months old.
Please advise as to what can be done to fix this.

Re:
It sounds like the Power transistor that drives the High Voltage Transformer shorted out. The rapid clicking sound you are hearing when pressing the power button now is that of the power supply starting to come up, detecting a short circuit and shutting back off again, preventing further damage. It is likely that the HV Transformer is shorted as well which usually causes the Output transistor to fail. Since the set is only 2 1/2 years old, it is probably worthwhile getting it to a repair shop as long as you have been very satisfied with the picture quality up to this point. If the picture size was larger than you needed, you might consider going down to a 37" LCD HDTV set. Toshiba is tops in this category IMHO.

see a tech,sounds like your tv is in need of repair if its under warranty send it back,if not be prepared to spend some cash.sounds to me your transformer and/or the capacitors have failed,its a common problem for these units, easy fix if you have some electrical experience. but once theses tv's reach this point its time to see a tech or get a new tv.
I have a similar problem with HULUplus - I think I'll return the TV to WalMart and try another brand. It's the second VIZIO I bought in the last 5 mos. that has had issues. The first TV had popping (sounded electrical) sounds, also cut out sometimes. Would U-Verse have something to do with it? That may be a dumb question, but who knows?
Hello Check its power supply regulator board. The pop sound you heard may be due to an explosion to any electrolytic capcitors on it. If the line voltage exceeds, this fault will happen. just repalce the damaged component. It is best to replace this board as card basis.
Sounds like either something went pop on the main pcb or in the power supply. Will need a repairman to take a look. & Just a caution if you're feeling adventurous, don't do it yourself unless you know what you're doing!!
no really, I am just a smart a$$ --- but the loud pop sounds like it may have been one of the capacitors in the power supply board. check for a POPPED cap (rare) and if there is one, test the components in the related circuit - as SOMETHING had to happen to make a cap fail like that - maybe a voltage regulator? give it a look..
Try 2 different signal sources, such as cable and DVD or Dish and DVD or Cable and vcr. If the same problem exists on both sources then the TV needs a circuit board.
I would like a discription of "posterized" to help you more.
