Sorry about multi q's so frustrated.
Q- My Hitachi TV flashes red and blue before eventually turning on

PAULA, July 2016

Hitachi won’t come on . Just blue flashing light. Is it worth repairing. Or buy new one £300.

I see you mean the power light is flashing red / blue, rather than the screen is flashing red / blue. Thank you for that much.

Once again:

These may provide some clue - if you go looking for spares make sure you know the exact model number!
