Re: Static or popping sound

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems, to activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source.

JVC HD-56G886 tuner stopped working

My (unfortunate) guess would be the Tuner received a static discharge when you were changing the antennas... this time of the year is bad for static - if you're in a "Winter" climate.

Receivers have a very sensitive FET or MMIC amplifier right inside from the antenna connection to make it better for picking up distant stations.

However, this same "sensitive" amplifier is also prone to being destroyed by even a small static discharge... especially if the tuner had its power turned ON.

Sad to say, it's likely toasted... :-(
(I hope I'm wrong... but you have already tried all other possible solutions)

Static on Powering on

You can start out by resoldering all poor solder connections and look for bad capacitors they will be puffed up on Top.

My 50 inch dlp makes a crackling and popping sound, then starts to fade out and eventually makes a loud beeping sound. how do i fix this?

Look to see if this happens at all inputs--tuner and rear first.

This issue is not clear to me---sound is popping or you are hearing a sound from inside the set?

Tv speakers are not picking up audio from tv

Try unplugging the unit for 15 or 20 minutes. Sometimes the microprocessor needs to be reset in these units. Thanks

Loud audio pop

This is the type of problem that can drive a repair person or shop mad! The reason is that alot of times when a set is moved, the snapping from the High voltage does not occour. Your problem is one that deals with alot of dust and dirt in or around the High voltage block assy. And or a problem with one of the Picture tubes and or the High voltage leads going to the tubes, or a high voltage transformer that is going bad and is cracked. If you do not know the high voltage safety factors, you should not attempt to repair this set, as there is enough High voltage in this set to grab hold of you and shake you and to toss you to the other side of the room OR KILL you. My friend, this is a repair job for a pro to do! The longer you wait, though, to get the problem corrected, the more it will most likly cost you to repair. Good luck and if you get the set fixed or even if you do not , Please post back and let us know what you did to fix your problem?
