Please try this Press the 'Input/Source' Button > Press '2, 5, 8, 0' on the keypad of the remote > Scroll down to "Reset All" and press "OK" > Select "Yes" and press "OK". and let us know.
i just tried doing a reset and it worked.  all hd channels are working.  thanks. Find and push the "reset button" only thing i can think of is to maybe reflash the firmware. re-flash bios using usb stick if you can get that far.
if not reset option and steps like clearing cmos and pins.?
new mobo or try manufacturer.. send it to electronics recycling. why annoy yourself with bad performance. please delete the app and reinstall! it should work please extract the files and open the l1c product vial file > import > optical > sentinel-2 > l1c 
and then run again. Go to Settings->System->Advanced system settings->Factory reset

From the error message, it seems that the VRP software in the flash has been lost. I think you should download the firmware and upload it to the flash manually.  
You can download the firmware from here: [https://support.huawei.com/enter ... id-6691602/software](https://support.huawei.com/enterprise/en/switches/s2700-pid-6691602/software).  
  
You can upload the VRP software into the device via BootROM, please refer to: [http://support.huawei.com/hedex/ ... Startup&lang=en](http://support.huawei.com/hedex/hdx.do?docid=EDOC1000017232&id=dc_cfg_cfgm_0001&text=Configuring%2520System%2520Startup&lang=en). problem is a bad capacitor on the power board. caution if repairing yourself as capacitors in tv's hold a charge long after set is powered off and can be lethal. 
  
 when looking at your power board for a bad cap look at the top of the capacitors. a bad cap will have a noticable "bulging" on the top of it compared to others. be sure to note polarity of capacitor (will have a "-" on one side indicating negative. to fix on/off issue simply unsoldered bad capacitor and solder in a new one with same voltage and capacitance rating being sure the new capacitor is oriented the same as the old one was before it was removed.
