Question about Hitachi 43FDX15B 43" Rear Projection Television
First check Pico Fuse 05 they look like resistors but will be Green or Yellow and Check Q777 which is Transistor.
Another thing that can cause this is the STK ICs if everything is on pc05 and Q777 then replace both STK ICs they are big black ICs and will have PN# on them STK392-110s
Mats Electronics has them 1-800-628-1118 also CK RK42 3.3ohm resistor, RK46 1.5 ohm resistor they are near the STK ICs.

When you turn it on, does the red light sort of pulsate on and off?
Do you hear any odd sounds (a squeal, perhaps, as the red light flashes) coming from inside the set?
How old the unit is?
Let me know,so that we could proceed.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
