It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done. It is that sound that gives it away, this is a typical switchmode Power Supply problem.

Loud popping noise tv


EHT arcing takes place. Never switch the TV on, until this fault has been rectified. Doing so, will make too many other faults to occur. Contact any service technician.

Last night our TV made a loud popping noise then the picture went out. We still have sound but have trouble turning the TV off. What could this be and is it fixable? Thanks, Anne Marie Orcutt


Hi,
Question shows it is Vizio L32 lcd tv and symptom shows back light inverter board for defective for some reason and loud noise would be popping of any chip on inverter board.
Shopjimmy..com has replacement boards of that model on reasonable price and local tv repairman will replace defective board after checking/ testing the tv.
Hope these info will help.
Thanks.

My Toshiba Regza 32 inch lcd tv has a serious problem, on occasion the screnn will turn a fuzzy green color and turn itself off, usually a few loud popping noises also occur after it shuts off then the...


Model number means EVERYTHING to a real technician...
As a guess the popping noise could be arcing to ground - maybe from the inverter or one of the transformers on the inverter. The fuzzy green could be decoding the t-con board is attempting as this ground fault happens and shuts the unit off... I' would clearly have this checked before it does some serious damage. An ounce of prevention could save you pounds of cure....

My W3201C 32" LCD TV made a loud popping noise when I turned it off. Now it will not turn on. No power. No LED light.


That would be your transformer popping and dieing. Usually the popping is followed by a burning smell which is a good indicator that the part is unrecoverable. The cost of the part is variable based on the make and model TV and is usually not too labor intensive to replace. If not under warranty, let the repair gut know that you know what the problem is. Then, ask them to quote the cost of the replacement part and part number. Then ask them to quote you their hourly rate and get a time estimate. Then, google the part number and see if the cost is reasonable.

Loud popping noise


The 23" CRT set may have a high voltage breakdown in the flyback transformer or focus divider. Take the back off and operate the set in a dark room. Look for anything that has a blue glow around it or sparks flying when the pop occurs. I won't guarantee this will find your problem, but it is definitive if you see these!

I once had a set with these symptoms. I stopped the blue glow and arcing by covering the focus divider with epoxy. It worked for a couple of months before the divider literally broke apart.

Olevia LT27HVX 27 just blue screen


I just had this same problem over the weekend. Is your TV hooked up via HDMI?? Mine was and i've been having problems with the tv image shrinking whenever i turn on the tv, so i would have to change the channel 1 or 2 times for the image to come up normally. On Saturday I went to change the channel and then all of a sudden I hearld this loud pop and when the image came on it was just a sky blue screen, I couldnt see anything, but I could hear the channel. So I disconnected the HDMI and hooked up the tv with component cables I had and now it works fine. I ordered a new HDMI cable just to see if it will work again. If not, i'm calling Olevia.
