    Thanks for model number info.
    Please unplug tv from wall socket for minute to get it reset, replug back in and turn it On, if this does not solve the problem then tv got problem with either back light inverter boards or power supply board as power supply board has standby power supply and main power supply sections. Standby power section is working that you see blue light but main power section seems defective and become unable to provide power to entire circuit boards to work.
    Board replacement is job of Professional so contact local tv repair shop to get tv fixed.
    Thanks.

Bush IDLCD26TV16HD blue flashing light?


It is on protection mode due to some defects on the board. Switch off the TV manually, remove the plug and cool it off for 48 hours and retry. If nothing works, better refer it to a qualified service technician.
