32 inch astar 1080i lcd keeps having invalid input pop up which then leads to the tv switching to standard mode (channel 8 for example). Then I have the hd button to go back to whatever channel I was watching at the time. This problem occurs every 5-20mins and is also accompanied by the volume bar popping up right before the problem occurs.
I have the same problem in the office, but, not at home. I believe the IR sensor is confused by office florescent lighting, which has an unperseptible 60-cycle flicker not charactoristic of home incandescent lighting. Energy saving compact florescent probably have the same effect.
I have attached a dark tube over the sensor with relative success. This cluge is an unfortunate compensation for poor engineering because of the reduced angle of reception (the remote has to be directly in front of the sensor).

You need to use the TV remote, and change the input to video, or DVR ...or something. Run through the various input channels, and you will find it. Invalid format is like if my TV is set to RGB/PC input, but the screen has timed out and is in sleep mode (no display) ...it puts invalid format on the screen. Or if you go to straight TV instead the channel that's connected to the box, same thing. You have to have the right input selected. You usually need the remote for it.
It sounds as if the output resolution of your cable box is too high for the TV to accept.
If you are using HDMI, you might need to change the output of your cable box to a lower resolution (ie 1080p down to 720p)
To do this, connect a standard composite cable from your cable box to another input on the TV. Switch your TV over to that input and go through the display settings on your cable box. Lower the resolution, and then swap back over to your other cable.
If you are using HDMI, the source resolution could be too high. Your TV is only 720p so if your equipment is set for 1080p, it will not display. Connect the composite (yellow) video lead to the TV and change to that input. Use the equipment's menu function and verify the resolution. Make sure it is set for 720p. Also try a different HDMI cable, yours may have a bad lead inside.
If you get that across all inputs or channels then your digital board is bad. If you get it only on one input such as HD cable box, HD satelitte receiver or Blu_Ray player then they are set for the wrong output on that connector. The TV most likely will only accept up to 720p or 1080i....
This model TV has specs for DVI, VGA, component video and S-video inputs. Are you using a DVI-HDMI cable? In that case, check your cable specs. DVI-I and DVI-D (single link and dual link) are not interchangeable and I would guess you have the wrong one connected to the HDMI for your unit.
My nephew had exact same problem, I fixed it by changing 8 puffed up capacitors in the power supply. They went out of business because they copied philips tv design and were sued by them.. The model was ltv-2601(canadian model) but all including ltv-2701, used cheap capacitors. Has been good for 4 months now.
Hello, According what you saying not recognize any iput. Then your main board is defective.
The HDMI and the YPbPr are the same connection according the main board build. Any other question please call 323-767-6030.
