Excel spreadsheet, 48.2 KB, about blind mode on some Videocon LED televisions. The name does not list models, so check the contents for the sets covered. Blind mode usually refers to entering service or factory settings, or reloading software, without a working picture, using a remote key sequence. A table like this helps a technician reset or configure a set when the panel shows nothing. Open it with Microsoft Excel, LibreOffice Calc or another spreadsheet program, and confirm the model and main board before applying any sequence.
