Hitachi LE55A6R9A picture out but sound works. Menu there with flash light test. No lights in back when rear panel is removed. Which should I replace? Power Supply Board? Main Board? T-Con Board?

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Hitachi LE55A6R9A audio no picture(can hold light near screen and see picture)


Test LED output voltage, if its missing look at the power board as being bad, also test the PWM voltage and make sure its between 2 and 4 volts, if its not correct the main board may be bad.
