SOURCE: High Pitch buzz noise when plugged in and it doesn't turn on

The tv has a shorted component and that is why is making the noise,call a qualified technician to find it and dont try to use it anymore.Is not a fuse.

before any attempt to deep cause of problem, unsolder first all the tack switches in the front panel of tv.then turn on the tv using remote control observe? cuz maybe one of the switches is stock.if not,proceed to eeprom servicing which is u have to look for service mode of ur tv model to unlock it and reset it to factory value.

SOURCE: TV Turned itself off, and won't turn on...makes a chirping noise

Sounds like the power supply. That's what the local place told me with the same symptoms.

SOURCE: Sharp Aquos turns itself off

How many times per second does the POWER led blink? (dont worry about the OPC).

1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board

You can buy the parts online and fix if yourself!!

CAMPORT STUCK on???


I had ot go online to buy a remote control to use with my zenith concierge tv. It is the same model # as yours. I ended up paying almost 40 dollars for a remote made by lg who I believe bought out zenith. I believe you could problably just get a universal remote and get the same thing accomplished. I can do everything with the remote I ordered except the one thing I wanted it for and that is to turn up the volume. It says on the menu, custom, not preset, but it still will only go up halfway no matter what I do. I heard that you could program the tv to factory settings but I tried that with another remote and all it did was reprogram the remote so that it didn't work anymore. If you have any suggestions as to how I can get the volume to work on my tv, I would appreciate it as well

Tries unplug,replug the tv back like an hour later.The tv,now will reset itself back to the factory setting.The tv should work now.If not,this problems,usally the cause it by the power supply board not responing and giving the the right voltages to the tv anymore.Tries websites like Shopjimy.com,Ebay.com to buy a refurbish power supply board for the replacement.

I have a 32 in insignia and a universal remote was used to try and turn channel..it turned the channel once and now its frozen on that channel even the tv remote wont work and the manual buttons on the tv...


Turn your TV off and unplug it for several minutes. Remove the batteries from any remote controls that you use for the TV, press all of their buttons, and install fresh batteries. Reset the TV to factory defaults. The universal remote control should not have caused any damage to the TV. If the problem persists, we recommend that you seek service by calling 1-888-237-8289 in the U.S or 1-866-237-8289 in Canada.

Universal remote locked out TV


I was able to get back to using the TV after several frustrating tries at finding the right combination of searches and pressing buttons. The function I was able access was not a function I could get to with the remote suppilied with the TV. And once stuck in this mode nothing would clear it Turns out that the power button gave me channel 8 and the #1 button gave me this display calibration? function. Obviously not using the right code. Never the less all is well with the TV and I got my VCR working with the $2.99 remote and I will attempt the other units TV and Magnasonic DVD later when I have regained my composure.

Tv wont turn on


take your tv to technician who can check your power supply, if your power is coming on and off, than a problem is not as big. firstly let him check a ht of a supply constantly, your supply is cutting.
