Question about Televison & Video
Battery Fully charged and inverter terminated the charging by it self. I turned off main and checked inverter output directly from inverter AC out let and the reading was 176 Voltage while there was no load on inverter. However, LCD indicator on inverter screen was showing 220 V output. I connected the phase wire in inverter out put socket and turned on two 23 Watts bulbs and inverter showed 184V output voltage in another socket of the room. Gradually volts increased to 192V. When I tuned of the both bulbs (when there was no load on the inverter it once again shows 179 V in the same socket). Three 23 Watts bulbs load on inverter, reading in socket showed 195V. Four 23 watts bulbs load on inverter, reading in same socket increased to 198 V and then I turned on a 40 Watts tube light and volts increased to 205V. Four bulbs and two tube lights, voltage in socket 202V. Then turned every thing off, meaning there was no load on the inverter and reading in socket gradually reduced to 179V. I repeated these steps three times and readings were strange. However, voltage output of inverter seemed to fluctuate while increasing the load or decreasing it. When there is some load on inverter during power outage then output voltage is better as compared with the inverter running without any load. 3rd Step Two 23 watts bulbs load on inverter, reading in socket was 191V. Three 23 watts bulbs load on inverter, reading in socket was 195V. Four bulbs and one 40 watt tube light, reading in socket was 202V. Four bulbs and two 40 watts tube lights, reading in socket was 199V. Four bulbs load on inverter and when I turned off both tube lights reading in socket was 212V. Turned off all loads and reading from socket was once again 179V. Meanwhile, when main is restored the LCD indicator on inverter shows the voltage which precisely corresponds with the voltage readings in the socket, inverter LCD indicator shows 129V as well as regarding on socket shows 128 V or 127V. (12 V 200 AH) Lead acid battery's output remained 12.1 V throughout this time. Kindly guide me that what is the issue. one other thing is that my cyberpower inverter some times takes so long to charge the batteries.

SOURCE: Volume and menu does not display
I had this problem on my Aquos (LC-46D62U). It was NOT a hardware problem. I recommend turning off the television. Next unplug the television for 5 to 10 seconds. This resets something for the television. Plug it back in and turn on the television. You should now be able to get your volume and other on-screen displays.

You should check the 12 volts capacitors on your power supply for dry or leaky, bulging conditions.
Replacing those capacitors will restore the functionality of your TV.

SOURCE: Low voltage output from inverter
I am thinking this a high impediance device problem and this is normal operation - the user manual of my inverter warns about use with high impediance devices - if not I am interested also...
