Everytime I change a channel on my LCD Tv Hi Sense 32

It has a faulty processor. Unfortunately this TV won't be worth fixing. Put up with it for as long as you can .

Tries tv and the box unplug,replug it back like about an hour later.For the tv to do a resetting itself back to the factory setting.The box to upgraded it softwares.Tv should be working again.If still have the same problems.Take ur tv backcover aparts and disconnection of the tv side manual control board PCB wire connection plug in that have like Power,Channel - +,Volme - + and Menu so on buttons switches.Turn the tv on and see if tv funtions correctly If yes than the tv manual cotrol buttons PCB board have to be change.If the manual contol board is diconnected from the tv Tuner signal board and have the same problems.Than ur tv have a bigger problems,the tv Tuner signal board is the causes and the problems.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish manual control PCB board or the tv Tuner signal boards for the replacement.

The problem is more likely to be with the wireless headphone set rather than the TV. It makes no sense that the signal changes channels. The only difference betweent he fixed and variable output is whether or not the volume changes the output signal amplitude. The channel selection process is not handled there. The distortion is likely due to the input of the wireless being overdriven. If available, turn down the input gain on the wireless and try again. Please update this with the results.

Thanks,

I have the same problem, did you ever get this fixed?

Unplug TV set from the outlet, wait 30 seconds, plug it back in, select right input with your remote if you using cable box or Punch the channel that you want to watch if you have cable service connected directly to the TV.

this meens no signal is being recived.
tv might have problems.

The black box is a text box for closed captioning. Some stations send the signal which turns on the box while not actually broadcasting any text. Go into your setup menu and turn off closed captioning, or at least change it to a different mode. The easiest option is to restore factory presets.

call 909-974-2859, they have the parts and tech support for this TV.

Hi,

The Tv needs to be serviced by a technician.Probably there is a problem with the circuits inside.

I have one in my shop with the same problem. Power is the only function that works. I repaired the power supply six monts ago. Now it looks like a bad digital processor board which is non-repairable. I can't believe what's happened to the tv business. Absolutely disgusting!
