This may be caused by the high voltage arcing inside the set. This is most commonly caused by dust buildup on the electronics. A thorough vacuuming, with the set off & unplugged, may cure the problem. Use care not to disturb any of the components inside, as many are delicate. Compressed air(30PSI max.) may also be used.

I have an lg ru42px11 plasma tv and the sound works but there was just a pop and the picture just went out. What boards would I try to trouble shoot with?


Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

The tv was giving as a gift in 2012. So I believe that I put the right model in. I was watching the tv and went to change the channel, when I noticed that the box with the channel number looked differ


Your symptoms point to the main board [the board with all the input connections], no simple fix, you must replace the board. Less likely the keypad is bad, just unplug the keypad and see if channel display stops popping up.

2010 VW CC factory stereo amp popping sound


If the amplifier itself is making the popping sound I suggest you disconnect it immediately, as it could be an electrical short within the amp. If the popping sound is actually coming from the speakers, it could be due to a crossed wire, blown amp channel, or blown speaker. If you posses the technical know-how, you can test the amp channel and speaker by connecting a different speaker to the channel responsible for the popping sound. If the new speaker makes the same popping noise then it is most likely a blown channel. I hope this helps =)

When i play dvd i hear background music really clearly and voices are hardly audible - this happens on channel 5.1. if i swap to channel 2. i hear the filmmaker commentary! dvd was working fine until...


sounds like the speakers are out of order and/or maybe 1 or 2 not connected. use a AA battery and "pop" each speaker wire. it's low voltage and amperage so it won't damage your speakers. but the pop will allow you to know exactly what speaker you have and if it's connected. now make sure to put it in the correct spot. i would start with the center channel. sounds like this one's not connected.
please rate if this was helpful!

While playing, my Roland KC-550 will make a loud pop and the sound will stop for a moment. It then starts right back playing. Sounds almost like a short???


Sounds like some solder / component connections have failed
Have a tech check solder joints on the power supply and output amp
I see this on a reg basis

HD channels look terrible


You may not have the resolution set to hd even though you are on the channel. Confirm that you are using hd cable and your set is displaying 720p or greater. This will sometimes pop up on the screen when you tune to a hd channel. it sounds like you are on 480 i or p. good luck

Popping and fading of sound


The "popping" sound could be electricity jumping from one place to another.An internal SHORT in a transistor, an internal OPEN in a resistor.Intermittent [sometimes it does,sometimes it dose not] arcing electronic parts.
Dust [metal filings,very fine hair that burns like a fuse] & dirt [anything metal], arcing (shorted) capacitors.Bad connections on ANY ground connector.
Possible:: your surround sound MASKED the popping sounds by acting like a FILTER.Which lets me to think that your problem is in the audio section.
