Flashing blue red


Switch off the TV manually, switch off the power outlet, remove plug and retry after 48 hours. Then if the problem persists, this might need attention by a qualified service technician.

LG 26LG30 screen suddently went blank. Light flashing blue/red


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
