Re: hitachi 46ex3bc

I have the same problem with mine. i,m pretty sure that it is the built in surge protector is bad. Try unplugging the tv for 30 seconds then plug it back in and turn it on. If your surge protector has not completely gone bad this might work a few times. mine won't turn on at all anymore.

Picture is black. sound went out a few weeks ago and now all that seems to work is the red power lamp turns on and I hear a click but that's all. I am not concerned about the picture since it is c

The click is a power relay on the main board and if the red light is on I would suggest looking inside to see if it has more than one relay--follow the power cord into the set----some of these sets have one relay but others have up to 3.

They are know for sticking open or shut. A tap on them can free them..A look inside even by a novice may also reveal something burnt or unplugged etc.

Hi catfishbob,
You're lamp came to its peak burning life and now its dead that's why you can't power up the unit and the led light keeps flashing. Once the lamp replace with new one your unit will back to normal again. Click this link for the replacement

Hitachi 53uwx10ba turns on & off when off red flashing light/clic

Same problem. Replaced both convergence ICs about 5 months ago. Worked fince since then and just recently no sound, no video, blinking red on front panel and clicking sound. I suspect that the ICs went bad again and blew a resistor or two. I used cheap Chinese ICs instead of the Sanyo ones and thing this is why. I'll be looking at it again and post solution.

No picture or sound

Remove the rear panel. With the TV on you should see a red LED near the center of the PCB. There should also be 5 green leds, 3 to the left a 2 behind. If there is no red leds, check the fuses. If there are no green leds or maybe 1 or 2, disconect PSD5. It's a connector on the left side of the power board that connects to the audio board. It's the 3rd on fro the back. It's labled. With that disconected, turn on the set and look for the green leds. If all 5 light, the power supply is OK and you have a problem beyond that. If they don't all light you have a bad power supply.
