The popping noise is not a good sign. You definitely have a shorted horizontal IC and probably a bad flyback transformer. You will find several bad capacitors that contributed to this problem. The cost of repair will be more than your depreciated TV is worth. Sorry..look for a new one. Thanks for asking and show a few hands of support!

Just changed build yesterday. Today tv has a dark shadow in the upper left corner. Reset tv. Checked inside for any blockage. Nothing noticeably wrong.

    Is this TV a newer flat screen or the old big and heavy tube type TV?

Our jvc tv made a popping sound and now has no picture. It also buzzes 3 times and the red and blue lights flash fast on front.


Something went bye bye. Check out your power supply for bad, burned components and/or blown caps - the latter often explode in their death throes.

The power comes on and then turns off and the front green power light blinks.


There is a small IC in the power supply section,
not the IC regulator that's the problem.

TV was on and had a picture, and then nothing w/flashing power


Your lamp has blown. Time to get a new one.

the hyperlink button doesn't seem to be working, but just copy and paste this link into your browser. It is linked directly to your tv's replacement bulb.

Jvc i art pro doe not turn on


The clicking sound is the TV trying to restart itself. It generally attempts this several times before giving up. The blinking code indicates the type of error (error codes are documented in the manual for the TV). The most likely cause is a burned out bulb, but could be something else.
If it is a bulb, it is usually replaceable without a service technician, and at a cost far less than $450.
Good luck.

Loud popping on jvc av56wp74


if the noise is from inside the tv in the back,the high voltage transformer that feeds the anode for the rgb tubes,28000volts probably is arcing.

TV wont power on, clicking noise and flashing standby led


Sounds pretty bad to me, I had a computer monitor that did a similar thing when plugged in after blowing, it's not a good thing. I didn't even bother to mess with it. You may have to replace the whole power board or at least have a whole handful of pieces to re-solder. It most likely isn't worth it unless your other tv's are under 30" and you don't have a lot of money ;)
