Loud electrical sounds

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.

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.

TV shuts off after watching netflix or it starts to reboot

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?

Watching TV and all of a sudden a loud pop came from the back of the set. Doesn't turn back on after unplugging.

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.

While watching the tv, there was a sudden loud, sharp pop, sounding like a gun shot, and the picture went blank

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 Picutre

someone shot your tv.

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.

While watching tv, the tv all sudden goes snowy, no sound, and have to turn it off and back on to make it work again

Connect up another set right next to that set thats going out to make sure the cable or that line is not bad. It soukds as though you may have an intermittant tuner assembly inside the TV set. Its also a possablity that there could be a bad solder connectiuon in or around the tuner assembley. Not really a job for the user, as this set has hot and cold chassis, and can give a mean shock if you do not have the know how to work on these monsters. good Luck PS Please do not forget to rate this thread.
